Unit Control Voltage Wiring
230/208V 1 phase and 3 phase equipment use dual
primary voltage transformers. All equipment leaves the
factory wired on 240V tap.
It is very important that
the correct voltage tap is used.
For 208V operation,
reconnect from 240V to 208V tap (see Figure 15 on
page 18). The acceptable operating voltage range for
the 240 and 208V taps are: 240V Tap (253 – 216)
and 208 Tap (220 – 197).
NOTE:
The voltage should be measured at the field
power connection point in the unit and while
the unit is operating at full load (maximum
amperage operating condition.
breaker boot. This allows unit power to be disconnected
without panel removal.
Route all field wires in channel under the control panel
as shown in Figure 13.
See Figure 14 to reference VAC landing points.
When running wires to unit from shelter, be careful to
not place wiring and conduit where it will interfere with
opening filter access doors.
