> Note 1. Relay is delivered as "reset" status unless specified otherwise. However, the status may change due to the shock from transportation or mounting operations. Therefore, it is recommended the relay should be set to the expected status via a power supply before being used. Note 2. In order to maintain "set" or "reset" status, the energizing voltage to coil & the pulse width shouldn't lower then the rated value. Note 3. Do not energize both of set and reset coil simultaneously. 

Note 4. Energizing time longer than 1,000 ms should be avoided.

## **Safety Precautions** 

- **Please refer to "PCB Relays Common Precautions" for correct use.** 

## Correct Use 

##  **Installation** 

- The relay contacts are polarized. Incorrect wiring may cause a failure to break the circuit. Wire the Relay with care. 

- Install the Relays in locations that are as dry as possible and have as little dust, dirt, and harmful gas. 

- Using the Relay under high temperature, high humidity, or harmful gas may deteriorate its performance characteristics due to condensation or corrosive materials, resulting in failure or burn damage to the Relay. 

##  **Relay Service Life** 

- The electrical durability of these Relays is specified as the number of load switching operations under a resistive load and OMRON-specified standard testing conditions. The coil drive circuit, ambient environment, switching frequency, or load conditions (e.g., inductive load or capacitor load) may reduce the service life and possibly lead to failure to break. Always confirm the service life in the actual equipment. 

##  **Wiring** 

- Be sure to tighten all screws to the appropriate torque given below. 

- Loose screws may result in burning due to abnormal heat generation during energization. 

- M5 screws: 1.57 to 2.35 N·m 

- Use a spring washer in order to prevent deformation and looseness. 

- Allow suitable slack on leads when wiring, and do not apply excessive force to the terminals. 

Please check each region's Terms & Conditions by region website.
