CAUTION
࡛
Select the power cable in accordance with relevant
local and national.
࡛
Wire size must comply with local and national code.
࡛
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
࡛
Connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be

࡛
You must keep the cable in a protection tube.
࡛
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, 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.
Step 13 Optional: Extending the power
