OPERATING INSTRUCTIONS
Turn all load equipment ON.
Turn the Isolation Transformer circuit breaker ON.
Observe that the front-panel green LED is illuminated.
Observe that the red LED (marked
) is not illuminated
(place the Isolation Transformer on a non-grounded
surface such as a carpet, wooden table, or magazine for
this test).
CAUTION:
If the red LED is continuously flashing, the wall receptacle
(powering the Isolation Transformer) is not connected to
the system safety ground. Immediately contact an electri-
cian to correct the wiring discrepancy.
IMPORTANT NOTE:
The red LED is not intended to test general wiring integ-
rity. Hot-neutral reversal, neutral-ground reversal, and/or
other wiring errors will not illuminate the red LED.
Once the Isolation Transformer has been properly in-
stalled per the installation instructions, the Isolation
Transformer and load equipment can be turned ON/OFF
via the Isolation Transformer circuit breaker (and if not
externally circuit breaker equipped, via the panel circuit
breaker).
