f Connect the rated cables only.
f Connect using a driver which is able to apply the rated torque to the screws.
f If the terminal is loose, re may occur caused by arc. If the terminal is connected too rmly, the terminal may be damaged.

• When connecting cables, you can connect the cables to the electrical part or connect them through the holes
below depending on the spot.
• Run transmission wiring between the indoor and outdoor units through a conduit to protect against
external forces, and feed the conduit through the wall together with rergerant piping.
• Remove all burrs at the edge of the knock-out hole and secure the cable to the outdoor knock-out using lining
and bushing with an electrical insulation such as rubber and so on.
• Must keep the cable in a protection tube.
• Keep distances of 50mm or more between power cable and communication cable.
• When the cables are connected through the hole, remove the Plate bottom.
