8.5.2 Power Connection
Provide the CPD1 (IN) connector, shown below, with the power
necessary for printed circuit board operation and that for DI operation.
To facilitate power division, the power is output to CPD1 (OUT)
exactly as it is input from CPD1 (IN). When power division is
required, use CPD1 (OUT).
Up to 1.0 A can be supplied by branching.

(Contacts: Japan AMP 1-175218-5)
NOTE
The specification of the power supply connector
CPD1 (IN) is the same as that for CPD1 (OUT).
There are no indications on the printed circuit
board to distinguish between the IN and OUT
connectors. Do not turn off the +24 V supply to
the connector during operation. Turning off the
+24 V supply will cause a CNC communication
alarm. When turning on the power, the +24 V
supply to the I/O module must be turned on before
or at the same time as the power supply to the
CNC. When turning off the power, the +24 V
supply to the I/O module must be turned off after or
at the same time as the power supply to the CNC.
