5.3 Wiring of Input and Output

5.3.1 Precautions Common to Input and Output

■
Wiring arrangement
Arrange the wiring so that the input and output wiring are separated, and these wirings are
separated from the power wiring, as much as possible. Do not route them through the same
duct or tie them in a bundle. Separate the I/O wires from the power and high voltage wires by at
least 100 mm.
■
Selection of wires
Be sure to select the thickness (dia.) of the input and output wires while taking into
consideration the required current capacity.
■
Power supply
Wiring should be carried out after the power supply to the GM1 was turned OFF. Also turn OFF
the power supply when connecting the GM1 Controller to expansion units. If they are connected
during the power supply is on, it may cause the fault or malfunction.
