In case of extending the electric wire, please DO NOT use a round-shaped pressing socket.
- Incomplete wire connections can cause electric shock or a fire.
WARNING
Select the power cable in accordance with relevant local and national regulations.
Wire size must comply with local and national code.
CAUTION
For the power cable, use the grade of H07RN-F or H05RN-F materials.
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 whole indoor units.
If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power is exceeded over
10% of supply rating, the indoor unit is protected, stopped and the error mode indicates.
To protect the product from water and possible shock, you should keep the power cable and the connection cord of the
indoor and outdoor units in the iron pipe.
Connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated in the fixed wiring[≥1/8"(3mm)].
You must keep the cable in a protection tube.
Keep distances of 2"(50mm) or more between power cable and communication cable.
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(ELCB or MCCB+ELB) should be considered more capacity if many indoor units are connected from
one 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 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.
