1. Before wiring work, you must turn off all power source.
2. Indoor unit power should be supplied through the
breaker(MCCB, ELB) separated by the outdoor power.
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 F3, F4(for communication) when installing
the wired remote Control.
