All units except 208/230-v units are factory wired for the voltage
shown on the nameplate. If the 208/230-v unit is to be connected
to a 208-v power supply, the control transformer must be rewired
by moving the black wire with the

Field power wires are connected to the unit at line-side pressure
lugs at the main terminal block (TB1) or at factory-installed option
non-fused disconnect switch. (See Fig. 27). Max wire size is #2
AWG (copper only). See Fig. 26.
