Wiring Work

Power and communication cable connection
1.
Before wiring work, you must turn off all power source.
2.
Indoor unit power should be supplied through the
breaker(ELCB or MCCB+ELB) separated by the outdoor
power.
ELCB: Earth Leakage Circuit Breaker
MCCB:Molded Case Circuit Breaker
ELB:Earth Leakage Breaker
3.
The power cable should be used only copper wires.
4.
Connect the power cable{1(L), 2(N)} among the units within
maximum length and communication cable(F1, F2) each.
5.
Connect V1, V2(for DC12V) and F3, F4(for communication)
when installing the wired remote Control.
