Select the power cable in accordance with relevant local and national regulations.
Wire size must comply with local and national code.
CAUTION
Power Supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 57 / CENELEC: H05RN-F or IEC:60245 IEC 66/ CENELEC: H07RN-F)
You should connect the power cable into the power cable terminal and fasten it with a clamp.
The unbalanced power must be maintained within 10% of supply rating among all indoor units.
If the power is significantly unbalanced, it may shorten the life of the condenser. If the unbalanced power exceeds
10% of power rating, the indoor unit will stop operation due to its built-in protection and display an error code.
To protect the product from water and possible shock, you should properly protect the power cable and the
maintain the connection cord of the indoor and outdoor units in good protection.
Connect the power cable to the auxiliary circuit breaker. All disconnection points from the power supply must be
jointed as one single wire and its length should be over 0.12inch (3mm).
You must keep the cable in a protection tube.
Keep distances of 1.97inch (50mm) or more between power cable and communication cable.
The maximum length of power cables are decided within 10% of power drop. If it exceeds, you must consider
another power supplying method.
The circuit breaker (MCCB or ELCB) should be considered more capacity if many indoor units are connected from
one circuit breaker.
Use round pressure terminal for connections to the power terminal block.
For wiring, use the designated power cable and connect it firmly, then secure it to prevent outside pressure being
exerted on the terminal board.
Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the
head and make proper tightening impossible.
Over-tightening the terminal screws may break them.
See the table below for tightening torque for the terminal screws.
Tightening torque
M4
0.89~1.3 lbf·ft
In case of extending the electric wire, please DO NOT use a round-shaped pressing socket.
WARNING
- Incomplete wire connections can cause electric shock or a fire.
