GFCI MODULE TESTING AND RESETTING
PROCEDURE
The GFCI module should be properly tested at least
once every month or whenever it is tripped. To proper-
ly test and reset the GFCI module:
• If the module has tripped, first carefully remove any
load and check it for damage.
• If the equipment has been shut down, it must be
restarted.
• The equipment needs to be operating at high idle
speed and any necessary adjustments made on the
control panel so that the equipment is providing at
least 80 volts to the receptacle input terminals.
• The circuit breaker for this receptacle must not be
tripped. Reset if necessary.
• Push the "Reset" button located on the GFCI mod-
ule. This will assure normal GFCI operation.
• Plug a night-light (with an "ON/OFF" switch) or other
product (such as a lamp) into the Duplex receptacle
and turn the product "ON".
• Push the "Test" button located on the GFCI module.
The night-light or other product should go "OFF".
• Push the "Reset" button, again. The light or other
product should go "ON" again.
If the light or other product remains "ON" when the
"Test" button is pushed, the GFCI module is not work-
ing properly or has been incorrectly installed (mis-
wired). If your GFCI module is not working properly,
contact a qualified, certified electrician who can
assess the situation, rewire the GFCI module if neces-
sary or replace the device.
