TRANSFORMER SECONDARY
The output voltage of the transformer may be adjusted +5% from nominal using the taps shown above. First
disconnect the power and all load equipment. After removing the side panels, move the wire from the
"nominal" transformer tap to the desired adjustment tap to adjust output voltage up or down. Replace side
panels. Then energize the transformer and check for proper desired voltage at output before reconnecting
and energizing the load.
IMPORTANT NOTE: BE SURE TO ADJUST THE TAPS ON ALL THREE PHASES.
