AC Power and Ground
!
CAUTION:
CAUTION:
The system requires a dedicated AC power circuit that is not shared with other 
equipment and is not controlled by a wall switch. The AC receptacle must not be 
located under the Main Distribution Frame and must be easily accessible.
!
CAUTION:
CAUTION:
The latch only removes DC power from the cabinet. Unseating the power supply 
removes AC power from the power supply, but not from the cabinet. To remove 
AC power from the cabinet, pull the AC power cord from the AC appliance 
connector on the rear of the cabinet.
!
CAUTION:
CAUTION:
System grounding must comply with the general rules for grounding provided in 
Article 250 of the National Electrical Code (NEC), National Fire Protection 
Agency (NFPA) 70, or the applicable electric code in the country of installation. 
!
CAUTION:
CAUTION:
AC mains wiring and testing must be performed by a qualified electrician and 
must conform to Article 250 of the National Electrical Code (NEC), National Fire 
Protection Agency (NFPA) 70, or the applicable electric code in the country of 
installation
Check AC Power
Each CMC uses an auto-ranging 85 to 264 VAC power supply, 47 to 63 Hz, 330 W, 4.5 amps 
(100-120 VAC) or 2.3 amps (200 to 240 VAC), at 500 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.
Before powering up the system, check the AC power in the equipment room using a KS-20599 
digital voltmeter (DVM) (or equivalent).
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.
3. Measure the voltage between the neutral and ground side of the receptacle.
4. Verify that the meter reads 0 VAC. If not, have a qualified electrician correct the problem.
5. When finished, set the AC mains circuit breakers to OFF
