g. Connect power cable to a 208 VAC, 3 phase, 400 hertz power source
Apply power to power cable.
Use a multimeter set to AC voltage range of at least 250 volts for following tests.
Measure voltage between pin D of connector P1 and a good chassis ground.
Voltage must be zero (0). If more than zero voltage is observed, disconnect cable
and check power source. Correct problem at power source or at cable connection
With zero voltage on pin D of P1 connector, check voltages between remaining
pins as shown on Table 4-1. Voltages should be approximately as shown. If
voltages are not within ten volts of those indicated in Table 4-1, disconnect power.
Locate and correct problem.
Connecting power source with unit in operating position may
damage electrical components. Put mode selector switch to OFF.
Remove lower front panel.
After proper voltages are indicated on all pins of connector P1, connect P1 to
connector J1 on air conditioner.
Turn mode selector switch to COOL and immediately back to OFF.
Observe the condenser fan to determine the direction of rotation.
If fan rotation is clockwise, unit power cable is not wired properly. Exchange
wires connected to pins A and B at power source connection and repeat steps (7)
and (8) above.
Check unit operation in accordance with para. 2-6 through 2-12.
h. See air conditioner electrical schematic Figure 1-4, for additional wiring information.
