2.10.1 Auxiliary Transformer Line Voltage Tap Selection (Cont)
3.
Note the line-voltage tap position on this transformer as determined by the location of the wire on
the 208V or the 240V tap on the transformer primary. This is normally set to the 240V tap. Refer
to figure 2-11.
4.
Based on the nominal line voltage, set the transformer primary voltage tap as follows:
•
Loosen the clamping screws for the current line-voltage tap, and for the required line-voltage
tap.
•
Connect to the 208 V tap if the line voltage is 215 VAC or less.
•
Connect to the 240 V tap if the line voltage is 216 VAC or higher.
•
Retighten both of the clamping screws.

For 400 / 480 VAC generators:
The 400 / 480 V tap setting only needs to be changed if a 400 V generator is to be operated from 480 V
mains, or if a 480 V generator is to be operated from 400 V.
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.
3.
Note the line-voltage tap position on this transformer as determined by the location of the wire on
the 400V or the 480V tap on the transformer primary. This is set to the 400 or 480V tap to match
the line voltage specified at the time of the order. Refer to figure 2-11.
