## ● **Mounting** - Make sure that sufficient space is provided between relays when installing two or more relays side by side to facilitate heat dissipation. Insufficient heat dissipation may result in the relay malfunctioning. **==> picture [118 x 74] intentionally omitted <==** **----- Start of picture text -----**

## ● **Quick-connect Terminal Connections** - Do not pass current through the PCB of the load contact terminals (quick-connect terminals). • The terminals are compatible with Faston receptacle #187 and are suitable for positive-lock mounting. Use only Faston terminals with the specified numbers. Select leads for connecting Faston receptacles with wire diameters that are within the allowable range for the load current. Do not apply excessive force to the terminals when mounting or dismounting the Faston receptacle. Insert and remove terminals carefully one at a time. Do not insert terminals on an angle, or insert/remove multiple terminals at the same time. The following positive-lock connectors made by AMP are recommended. Contact the manufacturer directly for details on connectors including availability. |Type|Receptacle

## ● **Other Precautions** - The G5CA is a power relay designed for applications switching power loads such as heaters in electric household appliances. Do not use the G5CA to switch micro loads less than 100 mA, such as in signal applications. - Use fully sealed models if the relays will require washing. Flux-protection models may malfunction or the relay's performance may be otherwise adversely affected if cleaning fluid enters the relay. - Application examples provided in this document are for reference only. In actual applications, confirm equipment functions and safety before using the product. - Consult your OMRON representative before using the product under conditions which are not described in the manual or applying the product to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment, and other systems or equipment that may have a serious influence on lives and property if used improperly. Make sure that the ratings and performance characteristics of the product provide a margin of safety for the system or equipment, and be sure to provide the system or equipment with double safety mechanisms. **Note: Do not use this document to operate the Unit.** **OMRON Corporation Electronic and Mechanical Components Company** **Contact: www.omron.com/ecb** **Cat.
