Check AC Power
Each CMC uses an auto-ranging 85 to 264 VAC power supply, 47 to 63 Hz, 330
Watts, 4.5 Amps (100-120 VAC) or 2.3 Amps (200 to 240 VAC), at 500 VoltAmps
(VA). The AC power source can be 1 phase of 120 VAC with neutral (100 VAC for
Japan) with 15 Amp circuit breaker, or 1 phase of 220 or 240 VAC (200 VAC for
Japan) with 10 Amp circuit breaker. The AC cord uses a NEMA 5-15P plug or an
IEC 320 plug.

1. Measure the AC voltage between the hot and neutral side of the
receptacle.
2. Depending on the AC power source, verify that the meter reads 90 to 132
VAC or 180 to 264 VAC. If not, have a qualified electrician correct the
problem.
