## **Safet Precautions y** 

## ! **CAUTION** 

## **Installation and Installation Environment** 

- Be sure to conduct wiring with the power supply turned OFF, and always attach the terminal cover after completing wiring. Touching the terminals when they are charged may occasionally result in minor electric shock. 

- The G3NB may rupture if a short-circuit is applied to it. To protect against short-circuit accidents, install a protective device, such as a quick-burning fuse, on the power supply line. 

## **Maintenance** 

- The internal snubber circuit is charged and may occasionally cause minor electric shock. Do not touch the G3NB’s main circuit terminals immediately after the power is turned OFF. 

- The G3NB and heat sink will be hot and may occasionally cause minor burns. Do not touch the G3NB or the heat sink either while the power supply is ON, or immediately after the power is turned OFF. 

**==> picture [36 x 121] intentionally omitted <==**

## **Use and Storage** 

Do not use or store the G3NB in the following locations. Doing so may result in damage, malfunction, or deterioration of performance characteristics. 

- Do not use or store in locations subject to rain or water drops. 

- Do not use or store in locations subject to exposure to water, oil, or chemicals. 

- Do not use or store in locations subject to high temperatures or high humidity. 

- Do not store in locations subject to ambient temperatures outside the range –30 to 100°C. 

- Do not use in locations subject to relative humidity outside the range 45% to 85%. 

- Do not use in locations subject to condensation as the result of severe changes in temperature. 

- Do not use or store in locations subject to corrosive or flammable gases. 

- Do not use or store in locations subject to dust (especially iron dust) or salts or in locations subject to salt damage. 

- Do not use or store in locations subject to direct sunlight. 

- Do not use or store in locations subject to shock or vibration. 

## ■ **Important Notice** 

**1. The standard G3NB models are equipped with a varistor as a surge absorber.**

**2. All G3NB-1 models are equipped a terminal cover. (Except G3NB-240B)** 

**3. The reliability of the output device of the G3NA-240B is better than that of the G3NB. The output device of the G3NB is different from that of the G3NA-240B.** 

   - **If you need higher reliability, we recommend using the G3NA240B.**

## ■ **Precautions for Safe Use** 

## **Transport** 

Do not transport the G3NB under the following conditions. Failure, malfunction, or deterioration of performance characteristics may occur. 

- Conditions under which the G3NB will be exposed to water or oil 

- High temperatures or high humidity 

- Without proper packing 

- Conditions under which rapid temperature changes may occur, resulting in the formation of condensation. 

## **Use and Handling** 

- Do not obstruct the airflow to the G3NB or heat sink. Heat generated from an G3NB error may occasionally cause the output element to short, or cause fire damage. 

- Do not mount the G3NB when your hands are oily or dirty, e.g., with metal powder. These may cause G3NB failure. 

## **Use and Installation** 

- Mount the G3NB in the specified orientation. If the G3NB is mounted in any other orientation, abnormal heat generation may cause output elements to short or may cause burning. 

- Be sure to prevent the ambient temperature from rising due to the heat radiation of the G3NB. If the G3NB is mounted inside a panel, install a fan so that the interior of the panel is fully ventilated. 

- When mounting the G3NB to a heat sink or radiator, apply a thin layer of Momentive Performance Materials Inc.’s YG6260 or Sinetsu Silicone’s G746, or a similar product, to the mounting surfaces prior to mounting. 

- If a material with high thermal resistance, such as wood, is used, heat generated by the G3NB may occasionally cause fire or burning. When installing the G3NB directly into a control panel so that the panel can be used as a heat sink, use a panel material with low thermal resistance, such as aluminum or steel. 

- Use the specified heat sink or one with equivalent or better characteristics. Failure to do so may result in short-circuiting or burning of the output elements due to abnormal heating. 

- Tighten the G3NB screws securely when mounting the G3NB. Tightening torque: 0.78 to 0.98 N·m 

- Tighten the heat sink screws securely when mounting the G3NB. Tightening torque: 0.98 to 1.47 N·m 

## **Use and Wiring** 

- Abnormal heat generated by wires may occasionally result in burning damage or melting of the wire sheath, leading to electric shock. Use wires suitable for the load current. 

- Do not use any wires with damaged sheaths. These may cause electric shock or leakage. 

- Do not place wiring in the same conduit or duct as high-voltage lines. Induction may cause malfunction or damage. 

- Use wires of an appropriate length, otherwise improper operation, malfunction and burning may result due to induction. 

- Heat generated by a terminal error may occasionally result in fire damage. Do not operate if the screws on the terminal are loose.

## **Screw terminal’s Tightening Torque** 

|**Screw size **|**Tightening torque**|
|---|---|
|M4|0.98 to 1.47 N·m|
|M5|1.57 to 2.45 N·m|



- Abnormal heat generated by terminals may occasionally result in fire damage. When tightening terminal screws, be sure that no nonconductive foreign matter is caught in screw. 

- Turn OFF the power before doing any wiring work. Failure to do so may cause electric shock. 

## **Use** 

- Only use the G3NB with loads that are within the rated values. Using the G3NB with loads outside the rated values may result in malfunction, damage, or burning. 

- Use a power supply within the rated frequency range. Using a power supply outside the rated frequency range may result in malfunction, damage, or burning. 

- Use crimp terminals of an appropriate size for the wire diameter. Failure to do so may occasionally result in burning damage or melting of the wire sheath, leading to electric shock. 

- G3NB malfunction or fire damage may occasionally occur. Do not apply excessive voltage or current to the G3NB terminals. 

## ■ **Precautions for Correct Use** 

- Do not drop the G3NB or subject it to strong vibration during transport or installation, or this may adversely affect the characteristics or cause improper operation or malfunction. 

- Do not transport the G3NB in an unpackaged condition, or this may cause damage or malfunction. 

- Do not allow solvents, such as thinner or gasoline, to come into contact with any resin parts on the G3NB, or this may cause the markings on the G3NB to rub off. 

- Do not allow oil to come into contact with the cover of the terminal block on the G3NB, or this may cause the cover to turn whitish or crack. 

## **Mounting Orientation** 

When mounting the G3NB to a flat surface, refer to _Load Current vs. Ambient Temperature_ to reduce the load current by 30%. 

## **Output Noise Surges for AC Switching SSRs** 

Connect a surge absorber (varistor) to both ends of the SSR load, and in parallel with the load. Use varistors with the following elements. 

|**Line Voltage**|**Varistor Voltage**|**Surge Capacity**|
|---|---|---|
|<br>100 to 120 VAC|<br>240 to 270 V|<br>1,000 A min.|
|200 to 240 VAC|430 to 470 V|1,000 A min.|



## **Control Panel Installation** 

Installing an SSR in a closed control panel will cause the heat that is generated by the SSR to accumulate inside the panel, which may lessen the SSR’s flow of current or possibly have adverse effects on other electronic components inside the panel. 

Be sure to provide ventilation holes at the top and bottom of the control panel. The use of fans is recommended as a more effective means of ventilation.

   **2.** Do not locate any objects around the air inlet or air outlet, otherwise the objects may obstruct the proper ventilation of the control panel. 

   **3.** A heat exchanger, if used, should be located in front of the SSRs to ensure the efficiency of the heat exchanger. 

Solid State Relays **G3NB-1**

## **SSR Ambient Temperature** 

The rated load current of an SSR is measured at an ambient temperature of 40°C. 

An SSR uses a semiconductor in the output element. This causes the temperature inside the control panel to increase due to heating resulting from the passage of electrical current through the load. To restrict heating, attach a fan to the ventilation outlet or air inlet of the control panel to ventilate the panel. This will reduce the ambient temperature of the SSRs and thus increase reliability. (Generally, each 10°C reduction in temperature will double the expected life, according to the Arrhenius Equation.) 

**SSR rated current (A) 5 A 10 A 20 A 25 A 40 A 75 A 90 A Required number of fans per SSR** 0.08 0.16 0.31 0.4 0.62 1.2 1.44 

Example: For ten SSRs with load currents of 40 A, 0.62 × 10 = 6.2 Thus, seven fans would be required. 

- **Note: 1.** Size of fans: 92 mm[2] , Air volume: 0.7 m[3] /min, Ambient temperature of control panel: 30°C 

   **2.** If there are other instruments that generate heat in the control panel other than SSRs, additional ventilation will be required. 

## **Operating Conditions** 

- As protection against accidents due to short-circuiting, be sure to install protective devices, such as fuses and no-fuse breakers, on the power supply side. 

- Do not apply overvoltages to the input circuit or output circuit. Failure or burning may result. 

- Keep the cooling system running continuously during the ON/OFF operation of the SSR. This is to allow residual heat to dissipate while the SSR is OFF. 

## **Operating Ambient Temperature** 

The rated value for the ambient operating temperature of the G3NB is for when there is no heat build-up. For this reason, under conditions where heat dissipation is not good due to poor ventilation, and where heat may build up easily, the actual temperature of the G3NB may exceed the rated value resulting in malfunction or burning. 

When using the G3NB, design the system to allow heat dissipation sufficient to stay below the _Load Current vs. Ambient Temperature_ characteristic curve. Note also that the ambient temperature of the G3NB may increase as a result of environmental conditions (e.g., climate or air-conditioning) and operating conditions (e.g., mounting in an airtight panel). 

## **< For use in class I equipment >** 

Metal mounting supports must be sufficiently bonded to the PEconductor. 

If a mounting rail is used, the rail must be provided with an individual connection to the PE conductor. 

This can be achieved by using Protective Conductor Terminal Blocks in accordance with IEC 60947-7-2 or other means providing equivalent reliability. 

## **EMC Directive Compliance** 

EMC direcives can be complied with under the following conditions. 

- A capacitor must be connected to the input power supply. 

- A capacitor and varistor  must be connected to the load power supply. 

- The input cable must be less than 3 m. 

~~LOAD~~ INPUT G3NB OUTPUT 3 m Max. Recommended Capacitor (Film Capacitor) Load: 0.1 µF, 275 VAC Input: 1.0 µF, 275 VAC Varistor : 390 V, 25000 A 

## **EMI** 

This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference. 

## **Loss Time** 

The loss time will increase when the G3NB is used at a low applied voltage or current. Be sure that this does not cause any problems.

- Use a commercial power supply (50/60 Hz) for the Fan. 

- Be sure to turn OFF the power supply and wait for the blades to stop before inspecting the Fan. 

- High-precision ball bearings are used in the fan and these may be damaged if the Fan is dropped or otherwise subjected to shock. The life and characteristics of the Fan will be reduced if the bearings are damaged. Do not subject the Fan to shock. 

- The life of the Fan depends on the ambient temperature, As a guideline, the Fan life is 40,000 hours for continuous usage at 40°C. 

- Be sure there are no objects near the air vents that would restrict air flow and no loose objects, such as electrical lines. 

- The Fan is an OMRON R87F-A4A-93HP (200 VAC) Fan. Use the same model of Fan for replacement. 

- The recommended tightening torque for the Fan is 0.44 N⋅m. 

- Terminals equivalent to Faston #110 are used for the Fan power supply terminals. 

- Refer to the following table for the OMRON Fan power supply plug cables (order separately). 

|**Cable**<br>**length**|**UL certified**|**Complies with Electrical Appliance**<br>**and Material Safety Law (Japan)**|

- Connect the ground screw hole on the fan to **PE** . 

## **- Preventing Overheating with a High - capacity Heat Sink (Y92B P250NF)** 

- When the High-capacity Heat Sink is used, high-capacity switching at 75 A or 90 A requires forced cooling with a fan. Connect the Fan to a power supply according to its ratings specifications. 

- If the Fan stops due to a power supply error, due to foreign matter in the power supply connection, or due to aging, the Heat Sink will heat to high temperatures, possibly resulting in failure of the SSR or adverse affects on other devices. Implement an overheating prevention measure, such as turning OFF the load current, if the Heat Sink overheats. 

- A thermostat is provided to detect overheating. The thermostat uses a NC contact, i.e., the circuit will be opened for overheating. This thermostat can be used to stop the operation of the SSR. Implement an overheating prevention measure by using this signal to output an alarm or perform another response applicable to the system. Also, confirm that there is no problem with the overall system. 

- Do not connect the thermostat directly to the load power supply. Connect it to a contactor or other shutoff device connected above the SSR. 

- Terminals equivalent to Faston #187 are used for the thermostat terminals. 

- Do not place heat-dissipating silicon grease on the thermostat. 

- Do not solder the thermostat terminals. 

- The following diagram shows a protective circuit example.

## **- Ventilating a High capacity Heat Sink - (Y92B P250NF)** 

- Refer to _Ventilation Outside the Control Panel_ . 

## **Operating Conditions** 

- Do not apply currents exceeding the rated current otherwise, the temperature of the G3NB may rise excessively. 

- As protection against accidents due to short-circuiting, be sure to install protective devices, such as fuses and no-fuse breakers, on the power supply side. 

- Do not apply overvoltages to the input circuit or output circuit. Failure or burning may result. 

- Do not drop the G3NB or otherwise subject it to abnormal shock. Malfunction or failure may result. 

- Keep the cooling system running continuously during the ON/OFF operation of the SSR. This is to allow residual heat to dissipate while the SSR is OFF. (load current 75 A, 90 A models) 

- The Y92B-P250NF is a Class 1 device. 

- If compliance with EU standards is required, ground the Y92B-P250NF.
