3 Phase, 480 Volt
The following connection, with the voltage change-over
board set into the 480V set position (See Figure 23), can
offer THREE PHASE power at 480V. After hooking up the
hard wires to the lugs as shown in figure 24 below, 480V
will be the voltage output.
Single Phase, 480 Volt
The following connection, with the voltage change-over
board set into the 480V set position (See Figure 23), can
offer SINGLE PHASE power at 480V. After hooking up
the hard wires to the lugs as shown in figure 25 below,
480V will be the voltage output.

Single Phase, 277 Volt
The following connection, with the voltage change-over
board set into the 480V set position (See Figure 23), can
offer SINGLE PHASE power at 277V. After hooking up
the hard wires to the lugs as shown in figure 26 below,
277V will be the voltage output.
