2–VoltageChecks
First check nameplate on transfer switching device;
rated voltagemust be the same as normal and
emergencyline voltages.

Use extreme caution when using a meter to

measure voltages in the following steps.

Do not touch power terminals; shock, burns, or

death could result !

Performsteps 1 through 6 at the right. Observethe status
lights. See Figure 1–7.
OBlack circlemeans light is on.
PWhite circle means light is off.
* If necessary, adjust voltage r egulator on the generator
according to the manufacturer’s recommendations. The
AutomaticTransfer Switching Equipment will respond
onlyto the rated voltage specified on the Transfer
Switchingdevice nameplate.
Alsose e page 4–1f ort he HI–LOWvoltage adjust
settingin the controller. The LOW setting shifts all
voltage settings down 4.2%; for example, 240 V to 230
V.
