Installation Procedure
• 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.
Tightening torque (N·m)
M4 0.8 to 1.2
M5 2.0 to 3.0
• 1 N·m = 10 kg·fcm
CAUTION
• When connecting cables, you can connect the cables to
the electrical part or connect them through the holes
below depending on the spot.
• Connect the communication cable between the indoor
and outdoor units through a conduit to protect against
external forces, and feed the conduit through the wall
together with refrigerant 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.
