Electrical Wiring
!
CAUTION
•
When clamping the wiring, to prevent external pressure being exerted on the wiring connections, use the clamping material and
conduct fixing firmly.
•
When performing the wiring work, ensure that the wiring is proper and cannot cause the control box lid to open up, if so close the
cover firmly. When attaching the control lid, make sure that the wires are not affected.
• Outside the unit, keep the weak wiring (remote controller and transmission wiring) and strong wiring (earth and power supply
wiring) at least 50mm away so that they do not pass through the same place together. Proximity may cause electrical interference,
malfunction and breakage.
!
WARNING
If the fuses burn, please call the service dealer. Please do not replace by yourself, otherwise, it may lead to electric shock and other
injuries.
