(4) For wiring of the inverter which has one front cover, route wires between the control circuit terminal
block and front cover. If cables can not be routed between the control circuit terminal block and front
cover (approx 7mm), remove a hook of the front cover, and use the space became available.
For wiring of the inverter which has front cover 1 and 2, use the space on the left side of the control
circuit terminal block.

REMARKS
⋅ When the hook of the inverter front cover is cut off for wiring, the protective structure (JEM1030) changes to open
type (IP00).
⋅ If the terminal block of the FR-A7NC is removed, built-in terminating resistor can not be used. (Refer to page 13.)
When performing wiring using the space between the inverter front cover and control circuit
terminal block, take care not to subject the cable to stress.
After wiring, wire offcuts must not be left in the inverter. They may cause an error, failure or
malfunction.
