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[≥3mm(1/8")].
X You must keep the cable in a protection tube.
X Keep distances of 50mm(2") 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(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.
