SECTION 5 • TESTING
GENERAL
In the event the relay is not to be installed immediately, store the relay in its original shipping carton.
When the relay is to be placed into service, it is recommended that the operational test procedure in this
section be performed prior to installation.
RELAY OPERATING PRECAUTIONS
Before installation or operation of the relay, note the following precautions:
1. A minimum of 0.2 ampere in the output circuit is required to ensure operation of current operated
targets.
2. The relay is a solid-state device. If a wiring insulation test is required, remove the connection
plugs and withdraw the cradle from its case.
3. When the connection plugs are removed the relay is disconnected from the operating circuit and
will not provide system protection. Always be sure that external operating (monitored) conditions
are stable before removing a relay for inspection, test, or service.
4. Be sure the relay case is hard wired to earth ground using the ground terminal on the rear of the
unit. It is recommended to use a separate ground lead to the ground bus for each relay.
