460V 60Hz Operation
For 460V operation, install a #4 AWG jumper wire from 0V to 230V on each primary
winding (total of 3 wires). Now install a #4 AWG jumper wires from 0V on the first
primary winding to 0V on the second primary winding and another #4 AWG jumper wire
from 0V on the second primary winding to 0V on the third primary winding. Connect the
three phase primary power from the main contactor to each of the 230V connections that
are
without
jumper wires. See Figure 5-2.
Note When the primary voltage of TR1 is changed,
the control transformer TR2 must also be rewired for the correct service voltage.
For 460V
operation, connect the white wire of control transformer TR2 to TB1-13 and the black
wire to TB1-14.
