2.3.4.3. Wiring of main power supply and equipment capacity
Thickness of wire for main power supply and on/off capacities
(1) Follow local regulations and ordinances for technical
standards related to electrical equipment, wiring, and
specifications of each electric power company.
(2) Wiring for control (hereinafter referred to as transmission line)
must be situated at least 5 cm from the power source wiring
so that it is not influenced by electrical noise. (Do not insert
transmission line and power source wire in the same conduit.)
(3) Be sure to provide designated grounded work to outdoor unit.
(4) Never connect the main power source to the terminal block of
a transmission line. If connected, electrical parts will be burnt
out.
(5) Use a 2-core shield cable for connecting a transmission line to
TB5 of the connection kit. If transmission of different systems
are wired with the same multiplecore cable, which can result
in poor transmission and receipt and can cause incorrect
operation.
(6) The system will not operate if connected improperly.
TB2 : Terminal block for power supply
TB : Terminal block for transmission line to indoor unit
TB5 : Terminal block for transmission line to outdoor unit
(7) Before turning the indoor unit and the connection kit on,
be sure to set the switches.
(8) To turn the power on, turn on the indoor unit, connection
kit, then the outdoor unit, in that order.
(9) For identification purposes, list the indoor unit model names in
the nameplate on the control box of the connection kit.
(10) Provide grounding for the indoor unit and the connection kit
