To peel the fi lm from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening
the screw. On the other hand, an undertightened screw can cause faulty contact, which
will lead to a communication failure.
6.4. Connection of wiring
(1) Remove the control box cover and install each connection cable.
(2) After wiring is complete, secure the remote controller cable, connection cable, and
power cable with the cable clamps.
