Select the power cable in accordance with relevant local and national regulations.
X
Wire size must comply with local and national code.
X
For the power cable, use the grade of H07RN-F or H05RN-F materials.
X
You should connect the power cable into the power cable terminal
and fasten it with a clamp.
X
The unbalanced power must be maintained within 10% of supply
rating among whole indoor units.
X
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.
X
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.
X
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)].
X
You must keep the cable in a protection tube.
X
Keep distances of 2"(50mm) or more between power cable and
communication cable.
X
Maximum length of power cables are decided within 10% of power drop. If it
exceeds, you must consider another power supplying
method.
X
The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many
indoor units are connected from one breaker.
X
Use round pressure terminal for connections to the power terminal block.
X
For wiring, use the designated power cable and connect it firmly,
then secure to prevent outside pressure being exerted on the terminal board.
X
Use an appropriate screwdriver for tightening the terminal screws. A screwdriver
with a small head will strip the head and make proper tightening impossible.
X
Over-tightening the terminal screws may break them.
X
See the table below for tightening torque for the terminal screws.
