Precautions

Precautions for Correct Use
Installation
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.
.
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.

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 exces-
sive force to the terminals when mounting or dismounting the Fas-
ton 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 connec-
tors including availability.

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-pro-
tection models may malfunction or the relay's performance may be
otherwise adversely affected if cleaning fluid enters the relay.
