Precautions for Electrical wiring 
•  Electrical wiring work should 
be 
conducted only by authorized personnel. 
• 
Do 
not connect more than three wires to the terminal block. Always use round type crimped terminal lugs with insulated 
grip 
on 
the ends 
of 
the wires. 
•  Use copper conductor only. 
Selection 
of 
size 
of 
power supply and interconnecting wires 
Select wire sizes and circuit protection from table below.  (This table shows 20  m length wires with less than 2% voltage 
drop.)

incorporation 
in 
the fixed wiring. 
•  The distance between its two terminal blocks 
of 
indoor unit and outdoor unit should not 
be 
over 5m.  If exceeded, the 
diameter 
of 
the wire should 
be 
enlarged according to the local wiring standard . 
• 
Wiring procedure 
1) Remove set screws on the side before taking off the front panel toward the direction. 
2) Connect wires to the terminal block correctly and fix the wires with a wire clamp equipped nearby the terminal block. 
3) Route the wires 
in 
a proper way and penetrate the wires through the opening for electrical wiring 
on 
the side panel.
