6 ELECTRICAL CONNECTION
WARNING
1.Using the specified wires, ensure to connect the wires, and fix wires securely so that the external tension to the wires do not affect the connecting part of the terminals.
Incomplete connection or fixation may cause a fire, etc.
2.Be sure to connect ground wire. (grounding work) Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
3.Appliance shall be installed in accordance with national wiring regulations.
Capacity shortage of circuit breaker or incomplete installation may cause an electric shock or a fire.
REQUIREMENT
•For power supply wiring, strictly conform to the Local Regulation in each country.
•For wiring of power supply of the outdoor units, follow the Installation Manual of each outdoor unit.
•Never connect 208/230 V power to the terminal blocks (A, B etc.) for control wiring. (Otherwise, the system will fail.)
•Perform the electric wiring so that it does not come to contact with the
The coating may melt resulting in an accident.
•Run the refrigerant piping line and control wiring line in the same line.
•Do not turn on the circuit breaker of the indoor unit until vacuuming of the refrigerant pipes completes.
CAUTION
•Consult local building codes, NEC (National Electrical Code) or CEC (Canadian Electrical Code) for special requirements.
•This indoor unit has no power cord.
•If incorrect/incomplete wiring is carried out, it will cause an electrical fire or smoke.
•Be sure to install circuit breaker is not tripped by shock waves.
If circuit breaker is not installed, an electric shock may be caused.
•Be sure to use the cord clamps attached to the product.
•Do not damage or scratch the conductive core and inner insulator of power and system interconnection wires when peeling them.
•Use the power cord and system interconnection wire of specified thickness, type, and protective devices required.
Remote control wiring
•For single system, use 2 x AWG20 non polarity wire is used for the remote control wiring.
Wiring
1.Connect the connecting wire to the terminal as identified with their respective numbers on the terminal block of indoor and outdoor unit.
(4 x AWG12)
2.Insulate the unsheathed redundant cords (conductors) with electrical insulation tape. Process them so that they do not touch any electrical or metal parts.
