DIP SWITCH SETTINGS
Before continuing, verify the DIP switch settings on the generator control board. These switches have
been factory set but may have been readjusted, particularly if this generator is a re-install.

2.10.0 INITIAL
RUN-UP
This section describes the procedure for auxiliary transformer line voltage tap selection, and for initial
power-on of the generator after it has first been installed.
PLEASE OBSERVE THE FOLLOWING POINTS REGARDING THE MAIN DISTRIBUTION
TRANSFORMER:
•
IF USING A DISTRIBUTION TRANSFORMER WITH AN ISOLATED SECONDARY, THE
SECONDARY WINDING MUST BE A WYE (STAR) CONFIGURATION WITH THE CENTER
POINT GROUND-REFERENCED. DO NOT USE A DELTA-CONFIGURED SECONDARY, AS
THERE IS NO GROUND REFERENCE IN THIS CONFIGURATION.
•
IF USING AN AUTOTRANSFORMER TYPE DISTRIBUTION TRANSFORMER, THE A.C.
INPUT TO THE TRANSFORMER MUST BE GROUND-REFERENCED.
2.10.1 Auxiliary Transformer Line Voltage Tap Selection
For 208 / 230 V generators, the line voltage taps on the auxiliary transformer must be checked before
powering up the generator.
For 400 / 480 V generators, the auxiliary transformer line voltage tap is factory set to match the line
voltage that was specified at the time of the order. If these units are to be operated from other than the
rated line voltage (i.e. if a 400 V generator is to be operated from 480 V mains), the line voltage tap on
the auxiliary transformer must be changed as described below.
For 208 / 230 VAC generators:
1.
Verify that the mains voltage and current capacity is correct for the generator installation per
Generator Power Requirements
in chapter 1.
2.
Locate the auxiliary transformer inside the generator cabinet. Refer to chapter 1.
