CAUTION
• Ground the unit.
Do not connect the ground cable to a gas pipe, water
pipe, lightning rod, or a telephone ground cable.
Improper grounding may cause electric shock.
• Do not connect power supply cables to the transmission
or remote control terminals, as this will damage the
product.
• Never bundle the power supply cable and transmission
cable together. Bundling these cables together will cause
miss operation.
• When handling PCB, static electricity charged in the body
may cause malfunction of the PCB. Follow the cautions
below:
• Establish a ground for the indoor and outdoor units and
peripheral devices.
• Cut power (breaker) off.
• Touch metal part of the indoor and outdoor units for
more than 10 seconds to discharge static electricity
charged in the body.
• Do not touch terminals of parts and patterns
implemented on PCB.

A. For solid core wiring
(1) To connect the electrical terminal, follow the below
diagram and connect after looping it around the end of the
cable.
(2) Use the specified cables, connect them securely, and
fasten them so that there is no stress placed on the
terminals.
(3) Use an appropriate screwdriver to tighten the terminal
screws. Do not use a screwdriver that is too small,
otherwise, the screw heads may be damaged and prevent
the screws from being properly tightened.
(4) Do not tighten the terminal screws too much, otherwise,
the screws may break.
(5) See the table for the terminal screw tightening torques.
(6) Please do not fix two power supply cables with one screw.
