7. ELECTRIC WIRING WORK

7-1 GENERAL INSTRUCTIONS

• All wiring must be performed by an authorized electrician.

• All field supplied parts and materials, electric works must conform to local codes.

• Always ground wires. (In accordance with national regulations of the pertinent country.)

• Always turn off the power before performing the electric wire installation work.

• Follow the “WIRING DIAGRAM” attached to the unit body to wire the outside unit and indoor units.

• Properly connect wire of the specified wire type and copper thickness. Also use the included clamp to avoid

applying excessive force to the terminal (field wire, ground wire).

• Do no let the ground wire should come in contact with gas pipes, water pipes, lighting rods, or telephone

ground wires.

• Gas pipes: gas leaks can cause explosions and fire.

• Water pipes: cannot be grounded if hard vinyl pipes are used.

• Telephone ground and lightning rods: the ground potential when struck by lightning gets extremely high.

• A circuit breaker capable of shutting down the power supply to the entire system must be installed.

• This system consists of multiple BS units. Mark each BS unit as unit A, unit B . . . , and be sure the terminal

board wiring to the outside unit and indoor unit are properly matched. If wiring and piping between the out-

side unit, BS unit and an indoor unit are mismatched, the system may cause a malfunction.

• Do not turn on the power supply (branch switches, overload interrupters) until all other work is done.

7-2 EXAMPLE FOR THE WHOLE SYSTEM

7-3 POWER CIRCUIT, SAFETY DEVICE AND CABLE REQUIREMENTS

• A power circuit (Refer to Table 3) must be provided for connection of the unit. This circuit must be protected

with the required safety devices, i.e. a main switch, a slow blow fuse on each phase and the ground fault

circuit interrupter.

• When using residual current operated circuit breakers, be sure to use a high-speed type (0.1 second or

less) 30mA rated residual operating current.

• Use copper conductors only.

• Use insulated wire for the power cord.

• Select the power supply cable type and size in accordance with relevant local and national regulations.

• Use vinyl cord with sheath or cable (2 wire) of AWG 18-16 for transmission wiring.
