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. The acceptable
operating voltage range for the 240 and 208V taps are:
240V tap (253 – 216) and 208 tap (220 – 197). To
verify voltage and adjust voltage tap (if necessary), see
Figure 17.
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.
