6 . ELECTRIC WIRING WORK

6-1 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 supply before performing the electric wiring work.
• Follow the "WIRING DIAGRAM" attached to the control box cover to wire the outdoor 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 not let the ground wire come in contact with gas pipes, water pipes, lightning 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 Branch Selector units. Mark each Branch Selector unit as unit A, unit
B . . . , and be sure the symbols on the terminal blocks to the outdoor unit and indoor unit are properly
matched. If wiring and piping between the outdoor unit, Branch Selector unit and indoor unit are mis-
matched, the system may cause a malfunction.
• Do not turn on the power supply (branch switches, overload interrupters) until all other work is done.
