Step 4 Connecting the power and communication cables
Power and communication cable connection
• Before wiring work, you must turn off all power source.
• Connect the power and communication cable among the units within maximum length to set the voltage drop
under 10%.
• The auxiliary circuit breaker (ELCB, MCCB, ELB) should be considered more capacity if many indoor units are
connected from one breaker.
• Connect F3, F4(for communication) to the communication cable of the wired remote control.
• Tighten the electric wires with a proper tool within the torque limit to connect and fix them firmly, and then
organize the wires to prevent outside pressure being exerted on the covers and other parts. Failure to do so may
result in overheating, electric shock, and fire.
• To protect the product from water and possible shock, you should keep the power and the communication cables
of the indoor and outdoor units in the iron pipe.
• Connect the power cable to the auxiliary circuit breaker (ELCB, MCCB, ELB).
• Keep distances of 50mm or more between power cable and communication cables.
• Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 57 / CENELEC: H05RN-F or IEC:60245 IEC 66 / CENELEC: H07RN-F)
• Screws on terminal block must not be unscrewed with the torque less than 12 kgf•cm.
• When installing the indoor unit in a computer room, use the double shielded (tape aluminum / polyester braid +
copper) cable of FROHH2R type.
