## **Safet Precautions y** 

**Refer to Safety Precautions for All Solid State Relays.** ! **CAUTION •** | ~~P~~ **Minor electrical shock may occasionally occur.** ~~o~~ **Do not touch the G3PE terminal section (i.e., currentcarrying parts) while the power is being supplied. • Also, always attach the cover terminal.** ~~A~~ **The G3PE may rupture if short-circuit current flows. • As protection against accidents due to shortcircuiting, be sure to install protective devices, such • as fuses and no-fuse breakers, on the power supply side.** 

## **Installation and Handling** 

- Do not block the movement of the air surrounding the G3PE or heat sink. Abnormal heating of the G3PE may result in shorting failures of the output elements or burn damage. 

- Do not use the G3PE if the heat radiation fins have been bent by being dropped. Doing so may result in malfunction due to a reduction in the heat radiation performance. 

- Do not handle the G3PE with oily or dusty (especially iron dust) hands. Doing so may result in malfunction. 

- Attach a heat sink or radiator when using an SSR. Not doing so may result in malfunction due to a reduction in the heat radiation performance. 

## **Installation and Mounting** 

**Minor electrical shock may occasionally occur. Do not touch the main circuit terminals on the SSR immediately after the power supply has been turned OFF. Shock may result due to the electrical charge stored in the built-in snubber circuit.** 

- Mount the G3PE in the specified direction. Otherwise excessive heat generated by the G3PE may cause short-circuit failures of the output elements or burn damage. 

- Make sure that there is no excess ambient temperature rise due to the heat generation of the G3PE. If the G3PE is mounted inside a panel, install a fan so that the interior of the panel is fully ventilated. 

**Minor burns may occasionally occur. Do not touch the SSR or the heatsink while the power is being supplied or immediately after the power supply has been turned OFF. The SSR and heatsink become extremely hot.** 

- Make sure the DIN track is securely mounted. Otherwise, the G3PE may fall. 

- When mounting the heat sink, do not allow any foreign matter between the heat sink and the mounting surface. Foreign matter may cause malfunction due to a reduction in the heat radiation performance. 

- If the G3PE is mounted directly in a control panel, use aluminum, steel plating, or similar material with a low heat resistance as a substitute for a heat sink. Using the G3PE mounted in wood or other material with a high heat resistance may result in fire or burning due to heat generated by the G3PE. 

## ~~PT~~ **Precautions for Safe Use** 

OMRON constantly strives to improve quality and reliability. SSRs, however, use semiconductors, and semiconductors may commonly malfunction or fail. In particular, it may not be possible to ensure safety if the SSRs are used outside the rated ranges. Therefore, always use the SSRs within the ratings. When using an SSR, always design the system to ensure safety and prevent human accidents, fires, and social harm in the event of SSR failure. System design must include measures such as system redundancy, measures to prevent fires from spreading, and designs to prevent malfunction. 

## **Installation and Wiring** 

- Use wires that are suited to the load current. Otherwise, excessive heat generated by the wires may cause burning. 

- Do not use wires with a damaged outer covering. Otherwise, it may result in electric shock or ground leakage. 

- Do not wire any wiring in the same duct or conduit as power or high-tension lines. Otherwise, inductive noise may damage the G3PE or cause it to malfunction. 

## **Transport** 

- When tightening terminal screws, prevent any non-conducting material from becoming caught between the screws and the tightening surface. Otherwise, excessive heat generated by the terminal may cause burning. 

Do not transport the G3PE under the following conditions. Doing so may result in damage, malfunction, or deterioration of performance characteristics. 

   - Do not use the G3PE with loose terminal screws. Otherwise, excessive heat generated by the wire may cause burning. 

- Conditions in which the G3PE may be subject to water. 

- Conditions in which the G3PE may be subject to high temperature or high humidity. 

   - For the G3PE models with a carry current of 35 A or larger, use M5 crimp terminals that are an appropriate size for the diameter of the wire. 

- Conditions in which the G3PE is not packaged. 

- Always turn OFF the power supply before performing wiring. Not doing so may cause electrical shock. 

## **Operating and Storage Environments** 

Do not use or store the G3PE in the following locations. Doing so may result in damage, malfunction, or deterioration of performance characteristics. 

## **Installation and Usage** 

   - Select a load within the rated values. Not doing so may result in malfunction, failure, or burning. 

- Locations subject to rainwater or water splashes. 

   - Select a power supply within the rated frequencies. Not doing so may result in malfunction, failure, or burning. 

- Locations subject to exposure to water, oil, or chemicals. 

- Locations subject to high temperature or high humidity. 

   - The G3PE provides a circuit to prevent photocoupler damage by forcibly arcing the output element for surge voltages applied to the load. The G3PE therefore cannot be used for motor loads. Doing so may result in load motor malfunction. 

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

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

- Locations subject to corrosive gases. 

- Locations subject to dust (especially iron dust) or salts. 

- Locations subject to direct sunlight. 

- Locations subject to shock or vibration.

## **Precautions for Correct Use** 

The SSR in operation may cause an unexpected accident. Therefore it is necessary to test the SSR under the variety of conditions that are possible. As for the characteristics of the SSR, it is necessary to consider differences in characteristics between individual SSRs. 

The ratings in this catalog are tested values in a temperature range between 15°C and 30°C, a relative humidity range between 25% and 85%, and an atmospheric pressure range between 86 and 106 kPa. It will be necessary to provide the above conditions as well as the load conditions if the user wants to confirm the ratings of specific SSRs. 

## **Causes of Failure** 

- Do not drop the G3PE or subject it to abnormal vibration or shock during transportation or mounting. Doing so may result in deterioration of performance, malfunction, or failure. 

- Tighten each terminal to the torque specified below. Improper tightening may result in abnormal heat generation at the terminal, which may cause burning. 

**Terminals Screw terminal diameter Tightening torque** Input terminals M3.5 0.59 to 1.18 N·m Output M4 0.98 to 1.47 N·m terminals M5 1.57 to 2.45 N·m **•** Do not supply overvoltage to the input circuits or output circuits. ~~——~~ Doing so may result in failure or burning. 

- Do not supply overvoltage to the input circuits or output circuits. Doing so may result in failure or burning. 

- Do not use or store the G3PE in the following conditions. Doing so may result in deterioration of performance. 

   - Locations subject to static electricity or noise 

   - Locations subject to strong electric or magnetic fields 

   - Locations subject to radioactivity 

## **Mounting** 

- The G3PE is heavy. Firmly mount the DIN Track and secure both ends with End Plates for DIN Track mounting models. When mounting the G3PE directly to a panel, firmly secure it to the panel. 

- Screw diameter: M4 

Tightening torque: 0.98 to 1.47 N·m

- Make sure that all lead wires are thick enough for the current. 

- For three-element and two-element models, the output terminal will be charged even when the Relay is OFF. Touching the terminal may result in electric shock. To isolate the Relay from the power supply, install an appropriate circuit breaker between the power supply and the Relay. 

- Always turn OFF the power supply before wiring the Unit. 

- Terminal L2 and terminal T2 of a 2-element model are internally connected to each other. Connect terminal L2 to the ground terminal of the power supply. 

- If terminal L2 is connected to a terminal other than the ground terminal, cover all the charged terminals, such as heater terminals, to prevent electric shock and ground faults. 

## **Fuses** 

- Use a quick-burning fuse on the output terminals to prevent accidents due to short-circuiting. Use a fuse with equal or greater performance than those given in the following table. 

## **Recommended Fuse Capacity** 

|**Rated G3PE output**<br>**current**|**Applicable SSR**|**Fuse**<br>**(IEC 60269-4)**|

   **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 G3PE to ensure the efficiency of the heat exchanger. 

## **G3PE Ambient Temperature** 

15A and 25A models have ambient temperature of 40°C, while 35A and 45A models have 25°C ambient Temperature. The G3PE uses a semiconductor to switch the load. This causes the temperature inside the control panel to increase due to heating resulting from the flow of electrical current through the load. The G3PE reliability can be increased by adding a ventilation fan to the control panel to dispel this heat, thus lowering the ambient temperature of the G3PE. (Arrhenius's law suggests that life expectancy is doubled by each 10°C reduction in ambient temperature.) 

|**SSR rated current (A)**<br>15 A|15 A<br>25 A|35 A|45 A|
|---|---|---|---|
|**Required number of**<br>**fans per SSR**<br>0.23|0.23<br>0.39|0.54|0.70|



Example: For 10 G3PE SSRs with load currents of 15 A, 

0.23 × 10 = 2.3 

Thus, 3 fans would be required. 

- **Note: 1.** Size of fans: 92 mm × 92 mm, 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 in addition to SSRs, more ventilation will be required. 

   **3.** Ambient temperature: The temperature that will allow the SSR to cool by convection or other means.
