**G9SB** 

## **Safety Precautions** 

**Be sure to read the precautions** _**“Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”**_ **in the website at:http://www.ia.omron.com/.** 

## ! **CAUTION** 

Turn OFF the G9SB before wiring the G9SB. Do not touch the terminals of the G9SB while the power is turned ON, because the terminals are charged and may cause an electric shock. 

## **Precautions for Correct Use** 

## **Failure Detection for Slow-starting Power Supply** 

When using a power supply with a long start-up time, if power is switched on while input has been closed the internal circuits will detect a power voltage error and the product will not operate. Apply the voltage to the product once the voltage has reached its rated level. 

## **Installation** 

The G9SB can be installed in any direction. 

## **Wiring** 

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

- Tighten each screw to a torque of 0.5 to 0.6 N·m, or the G9SB may malfunction or generate heat. 

- External inputs connected to T11 and T12 or T21 and T22 of the G9SB must be no-voltage contact inputs. 

- Strip the wires by 7 mm max. 

## **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.) 

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. 

## **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. 

## **Mounting Multiple Units** 

When mounting multiple Units close to each other, the rated current will be 3 A. Do not apply a current higher than 3 A. 

## **Connecting Inputs** 

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

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

G9SB-200 @ - @ /301 @ - @ meet the requirements of Safety Category 4 of EN ISO13849-1 when they are used as shown in the examples provided by OMRON. Relays may not meet the standards in some operating conditions. The G9SB-3010 can be applied to Safety Category 3 of EN ISO 13849-1 using double breaking. 

The applicable safety category is determined from the whole safety control system. Make sure that the whole safety control system meets EN 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 IEC61496-1 EN81-1, EN81-2 

- UL standards: UL508 (Industrial Control Equipment) 

- CSA standards: CSA C22.2 No. 14 (Industrial Control Equipment) 

- CCC Certification: GB14048.5
