INSTALLATION
2.3 Wiring
Route the wires so that they do not take up a lot of space in the control circuit terminal block of the option unit.
Wire the twisted pair shielded cable after stripping its sheath to make its cables loose. Also, protect the
shielded cable of the twisted pair shielded cable to ensure that it will not make contact with the conductive
area.
During wiring, do not leave wire off-cuts in the inverter. They may cause a fault, failure or malfunction.
REMARKS
The wires with large gaze may not be connected to the terminal block. When connected in parallel, all wires may not
fit in the wiring space due to the increased number of wires. In such cases, perform wiring by using a junction
terminal block.
When installing the inverter front cover, the cables to the inverter's control circuit terminals
and option terminals should be routed properly in the wiring space to prevent them from
being caught between the inverter and its cover.
