4.2.3 Wiring for the Power Supply Part of the CPU Unit

 When the CPU unit is used with 24V DC power supply, perform wiring for power supply as
follows.
 Use the power supply cables (Part No.:AFPG805) that come with the unit to connect the
power supply.

24V DC
 When a programmable display GT series is connected to the GT power supply terminal
(24V) of the CPU unit, use it within the range of 21.6 to 26.4 V DC.
 Selection of a power supply
 Referring to Section 1.2, select a power supply larger than the capacity of the unit.
In the minimum configuration, select a power supply of 24 W or larger.
 In order to protect the unit against abnormal voltage from the power supply line, the power
supply should be an insulated type, and should be enclosed within a protective circuit. The
regulator on the unit is a non-insulated type.
 If using a power supply device without an internal protective circuit, always make sure power
is supplied to the unit through a protective element such as a fuse.
