•
You must keep the cable in a protection tube.
•
Keep distances of 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 out-side
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.
