Verify that the feeders have been
connected to the proper lugs.

Use extreme caution when using a meter
to measure voltages in the following
steps. Do not touch power terminals;

Perform steps 1 through 6 at the right. Observe the status
lights. See Figure 1–8.
● Black circle means light is on.
❍ White circle means light is off.
* If necessary, adjust voltage regulator on the generator
according to the manufacturer’s recommendations. The
Automatic Transfer Switch will respond only to the rated
voltage specified on the Transfer Switch nameplate.
1
Close the normal source circuit
breaker. The Transfer Switch
Connected To Normal and the
Normal Source Available lights
should come on.

3
Close the emergency source
circuit breaker. (Start generator,
if necessary.) The Transfer
Switch Connected To Normal
and the Emergency Source
Available lights should come on.
