INSTALLATION AND WIRING
(3)For wiring of the 30K(00620 (EC Version)) or less, 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 due to the increased number of cables, remove a hook of the front cover and use a space become available. For wiring of the 37K(00770 (EC Version)) or more, use the space on the left side of the control circuit terminal block.
Wiring can be also performed using a cable groove in the inverter side surface
Cut off with a nipper, etc.

REMARKS
When wires can not be connected to the terminal block due to parallel connection or will not fit in the wiring space due to large gauge or the increased number of cables, perform wiring by using a junction terminal block, etc.
CAUTION
Do not use empty terminals as junction terminals because they are used in the option unit. If they are used as the junction terminals, the option unit may be damaged.
When installing the inverter front cover, the cables to the inverter's control circuit terminals and option unit terminals should be routed properly in the wiring space to prevent them from being caught between the inverter and its cover.
After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or malfunction.
