Connect the rated cables only.
Connect using a driver which is able to apply the rated torque to the screws.
If the terminal is loose, fire may occur caused by arc. If the terminal is connected too firmly, 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.
CAUTION
• 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 refirgerant 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.
