Wiring
(continued)
Before connecting the wiring, be sure to turn the circuit breaker off. After all wiring arrangements are complete, turn the circuit breaker on.
If the power supply wiring is mistakenly connected to a terminal board other than the power supply terminal board, the devices to
be connected to this controller or this controller will malfunction. After connecting the wiring, confi rm that the power supply wiring is
properly connected.

*: Functional Ground
• Do not run the inter-unit control wiring through the same conduit as the power supply

• Use different inter-unit control wiring and power supply wiring so they can be
differentiated visually.
