Power Supply Units with Replacement Notification
Precautions when Replacing Earlier Units
The following precautions apply when replacing a C200HW-PA204/PA204S/PA204R with a C200HW-PA204C.
Terminal Wiring
• Be sure to wire the ground terminals correctly. Incorrect ground terminal wiring will adversely affect the
Unit's resistance to noise. (For details on terminal arrangements for each Power Supply Unit, refer to
Part Names and Functions on page 19.)
• The C200HW-PA204C is not provided with a service power supply and RUN output (RUN).
Startup Time
• The time from when the power is turned ON until the PC operation starts is approximately 1 second fast-
er. Make sure that the system will not be adversely affected by the change in timing.
Power Failure Detection Voltage
• The power failure detection voltage is 85 V. The PC will stop operating if the voltage drops below this
voltage level.
Note If the previously used Power Supply Unit was used with 200 to 240 VAC, power failures were detected when
the voltage dropped to 170 V or lower and the PC operation stopped. With C200HW-PA204C, however,
operation will not stop between 85 V and 170 V. Therefore, make sure that the system will not be adversely
affected by the change in detection voltage.
