6.5. Transmission line
CAUTION
Caution when wiring cable:
Whenstrippingoffthecoatingofleadwire,alwaysusetheexclusivetoolsuchasa
wirestripper.Ifthereisnoexclusivetoolavailablenecessarily,carefullystripthecoat-
ing by a cutter etc. so that the conductive wire is not damaged.
If it is damaged, it may lead to an open circuit and a communication error.
Pay attention to the following points while attaching wires on the terminal board.
• Do not attach 2 wires on one side.
• Do not twist wires.
• Do not cross the wires.
• Do not shorted at edge at root.
GOOD PROHIBITED
1 wire 2 pcs at one side Wires twisted
2 wires Shorted at edge Shorted at root
6.5.1 Transmission wiring specications

6.4. Selecting power supply cable and breaker
CAUTION
Obtain the distribution network operator's agreement about the power capacity of the
power supply system, specification of the cable and the harmonic current, and etc.
when you connect the outdoor unit with the power supply.
Regulation of wire size and circuit breaker differs from each locality, please refer in ac-
cordance with local rules.
Refer to the table for the wiring and breaker specifications of each installation condition.
