AC Power Source
• Supply 100 to 120 or 200 to 240 VAC.
• Keep voltage fluctuations within the specified range
Supply voltage Allowable voltage fluctuations
100 to 120 VAC 85 to 132 VAC
200 to 240 VAC 170 to 264 VAC
• If one power supply phase of the equipment is grounded, connect the
grounded phase side to the L
2
/N (or L
1
/N if so indicated) terminal.
Voltage Selector Shorted: 100 to 120 VAC
Open: 200 to 240 VAC
Short-circuit the voltage selection terminals with the shorting bracket supplied
as an accessory to select 100 to 120 VAC supply voltage. For 200 to 240 VAC
leave them open.
Isolation Transformer Noise between the PC and ground can be significantly reduced by connecting a
1-to-1 isolation transformer. Do not ground the secondary coil of the transformer.
Current Consumption The current consumption will be 120 VA max. (180 VA max. with the C200HW-
PA209) per Rack, and there will be a surge current of at least 5 times the max.
current when power is turned on.
24-VDC Output Use these terminals as the power supply for 24-VDC Input Units. Never exter-
nally short these terminals; PC operation will stop if these terminals are shorted.
These terminals are available on the C200HW-PA204S only.
Although the 24-VDC output can supply up to 0.8 A, the combined power con-
sumption for both 5 V and 26 V must be 30 W or less, i.e., the capacity of the
24-VDC output will be reduced if the Units mounted to the Rack consume a lot of
current. Refer to Appendix C Unit Current and Power Consumption for the con-
sumption current of each Unit.
