## **Safety Precautions** 

**Be sure to read the** _**Common Precautions for Safety Warning**_ **at the following URL: http://www.ia.omron.com/.** 

## **Safety Precautions** 

## **Meanings of Signal Words** 

|**WARNING**|Indicates a potentially hazardous situation<br>which, if not avoided, will result in minor or<br>moderate injury, or may result in serious<br>injury or death. Additionally, there may be<br>significant property damage.|
|---|---|
|**Precautions for**<br>**Safe Use**|Supplementary comments on what to do or<br>avoid doing, to use the product safely.|
|**Precautions for**<br>**Correct Use**|Supplementary comments on what to do or<br>avoid doing, to prevent failure to operate,<br>malfunction, or undesirable effects on<br>product performance.|



## **Meaning of Alert Symbols** 

**==> picture [32 x 32] intentionally omitted <==**

● Indicates prohibited actions Indicates a general prohibited action that cannot be specifically identified. 

● Indicates mandatory actions Indicates a mandatory action that cannot be specifically identified. 

## ! **WARNING** 

**==> picture [32 x 32] intentionally omitted <==**

Serious injury may possibly occur due to breakdown of safety outputs. Do not connect loads beyond the rated value to the safety outputs. 

The safety function may be impaired and cause serious injury. Connect the wiring properly to prevent the safety output from shorting the power supply or the load power supply. 

## **Precautions for Safe Use** 

- (1) Use the G9SB Unit within an enclosure with IP54 (IEC/EN60529) or higher rating. 

- (2) Be sure to turn OFF the Unit before wiring. Do not touch the terminals while the Unit is powered. Doing so may result in an electrical shock. 

- (3) Do not perform wiring work when there is a risk of lightning strikes. Doing so may result in electric shock. 

- (4) Do not apply any excessive voltage or current to the input or output circuit the G9SB. Doing so may result in damage to the G9SB or cause a fire. 

- (5) Use the specified power supply voltage. Do not use the Unit with a power supply having a large ripple, or a power supply in which an abnormal voltage is generated intermittently. 

- (6) Do not use the Unit for loads that exceed the contact rating values, such as the switching capacity (contact voltage, contact current). This will not only result in the loss of the stipulated performance, such as faulty insulation, contact welding, and improper contact, but can also cause damage or burnout. 

- (7) Durability varies greatly depending on switching conditions. When using the product, check its operation using real equipment under actual use conditions. Use it with a switching count that provides proper performance. Continuous use of the product with degraded performance will eventually cause a dielectric breakdown between circuits and may cause the product itself to burn out. 

- (8) Do not use the Unit in an atmosphere with inflammable or explosive gases. Electric arcs from switches and heat generated from relays may cause a fire or explosion. 

- (9) Do not use the product if it has been dropped or if the inside of the product has been disassembled.  Such a product will not only fail to produce the proper characteristics, it may also break or burn out. 

- (10) Connect an appropriate protective device (Fuse of 5 A current rating etc), if necessary, to protect against load short-circuiting and ground faults. Failure to do so could result in damage to the Unit or a burnout. 

## **Precautions for Correct Use** 

## **When using the Unit with a power supply that has a long startup time** 

When using the Unit with a power supply that has a long startup time, if the power is turned ON while  input circuit is still closed, the internal circuit detects a power supply voltage abnormality, and the product does not operate. Apply the power supply voltage to the product after it has reached the rated voltage. 

## **Handling** 

Do not drop the G9SB or shock or vibrate the G9SB excessively. Doing so may result in damage to the G9SB or cause G9SB to malfunction. 

## **Installation** 

The G9SB can be installed in any direction. 

## **Adherence of solvents** 

Take care to avoid the adherence of solvents, such as alcohol, thinner, trichloroethane, gasoline, etc. on the product. Adherence of solvents may cause the marking to be erased, and may degrade the product. 

## **Storage and installation location** 

Do not storage or install the Unit at the following locations as it may damage it or cause it to malfunction. 

1. In direct sunlight 

2. Where the ambient temperature is outside the -25 to 55 ° C range 

3. Where the relative humidity is outside the 35 to 85% RH range or where drastic temperature changes cause condensation to form 

4. Where the ambient atmospheric pressure is outside the 86 to 106 kPa range 

5. Where there is corrosive or inflammable gas 

6. Where vibrations or shocks exceeding the specified ratings are applied to the product 

7. Where water, oil, or chemicals may splash 

8. Locations with high amounts of dust, salinity, or metal powder 

## **Mounting multiple Units** 

- Installing multiple Units close to each other will cause the rated current to be limited to 3 A. Use the Unit at 3 A or less. 

- Keep a minimum distance of 10 mm between the adjacent G9SB Units if a current of 3 A or more is flowing through the output terminal. 

## **Mounting DIN track** 

Use an end plate (PFP-M, sold separately) on both ends of the G9SB Unit. 

## **Wiring** 

- Use the following to wire the G9SB. Stranded wire (Flexible wire): 0.2 to 2.5 mm[2] Solid wire: 0.2 to 2.5 mm[2] 

- Maximam stripping length: 7 mm Max. 

- Tighten the terminal screws to the stipulated torque to prevent them from resulting in malfunctioning of the Unit or heat generation. 

- Terminal screws tightening torque: 0.5 to 0.6 N ⋅ m 

- Make sure the inputs connected to T11 and T12 (T21 and T22) are no-voltage contact inputs. 

- Connect the (-) side of the power supply to the ground. You cannot use the G9SB Unit with a machine in which the (+) side is connected to the ground. 

**9** 

**G9SB** 

## **Feedback contacts** 

Use a device with feedback contacts capable of switching micro loads of 24 VDC, 5 mA. 

## **Connecting Inputs** 

If using multiple G9SB models, inputs cannot be made using the same switch. This is also true for other input terminals.

## **Ground Shorts** 

A positive thermistor (TH) is built into the G9SB internal circuit to detect ground shorts and shorts between channels 1 and 2. When such faults are detected, the safety outputs are interrupted. (Only G9SB-2002- @ /3012- @ is able to detect shorts between channels 1 and 2.) 

## **Resetting Inputs** 

When only channel 1 of the 2-channel input turns OFF, the safety output is interrupted. In order to restart when this happens, it is necessary to turn OFF and ON both input channels. It is not possible to restart by resetting only channel 1. 

## **Durability of Contact Outputs** 

Relay with Forcibly Guided Contact durability depends greatly on the switching condition. Confirm the actual conditions of operation in which the Relay will be used in order to make sure the permissible number of switching operations. 

When the accumulated number of operation exceeds its permissible range, it can cause failure of reset of safety control circuit. In such case, please replace the Relay immediately. If the Relay is used continuously without replacing, then it can lead to loss of safety function. 

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. 

If the short breakdown is repaired, the G9SB automatically recovers. 

**Note:** In order to detect earth short breakdowns, connect the minus side of the power supply to ground. 

## **Applicable Safety Category (EN ISO13849-1)** 

G9SB-200 @ - @ /301 @ - @ Safety Relay Units can be applied to PLe/ Safety Category 4. 

G9SB-3010 Safety Relay Units can be applied to Safety Category 3 if double breaking is used. The above is provided according to circuit examples presented by OMRON. Therefore, the above may not apply to all operating environments. 

The applicable safety category is determined from the whole safety control system. Make sure that the whole safety control system meets ISO 13849-1 requirements. 

## **Certified Standards** 

The G9SB-200 @ - @ /3010/301 @ - @ conforms to the following standards. 

- EN standards, certified by TÜV Rheinland: EN60204-1 EN60947-1 EN60947-5-1 EN ISO13849-1 EN62061 EN61496-1 EN 81-20, EN 81-50
