Correct Use

●Installation

Make sure that sufficient space is provided between relays when installing two or more relays side by side to facilitate heat dissipa- tion. Insufficient heat dissipation may result in the relay malfunc- tioning.

●Quick-connect Terminal Connections

·Do not pass current through the PCB of the load contact termi- nals (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 recom- mended. Contact the manufacturer directly for details on con- nectors including availability.

●Charged Terminals

The section marked with dotted circles (indicated by arrows) in the following diagram includes the charged terminals of the relay. When the relay is mounted on a PCB, make sure that there are no metal patterns on the section of the PCB facing the portion of the relay shaded in the following diagram..

●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.
