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specied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xtwopowersupplycableswithonescrew.
