Tighten the terminal screws to the specifi ed torques, otherwise, abnormal overheating
may be produced and possibly cause heavy damage inside the unit.

(Remote controller/ Y1, Y2)
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.
