Electrical connection

WARNING
• Use the specified wires for indoor and outdoor connecting wires. Securely fix them to prevent external forces
applied to the terminals from affecting the terminals.
Incomplete connection or fixation may cause a fire or other trouble.
• Connect earth wire. (grounding work)
Incomplete earthing cause an electric shock.
Do not connect earth wires to gas pipes, water pipes, lightning conductor or telephone earth wires.
• Appliance shall be installed in accordance with national wiring regulations.
Capacity shortage of power circuit or incomplete installation may cause an electric shock or a fire.
• Under no circumstances, the power supply wire or the indoor and outdoor connecting wire must not be
connected in the middle (Connection using a solderless terminal etc.).
Connection trouble in the places where the wire is connected in the middle may give rise to smoking and/or a fire.
CAUTION
• For power supply specifications, follow the Installation Manual of outdoor unit.
• Do not connect 220 – 240 V power to the terminal blocks (
Otherwise, the system will fail.
• Do not damage or scratch the conductive core and inner insulator of power and system interconnection wires during
peeling them.
• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.
The coating may melt resulting in an accident.
• Be careful of fan operation when the circuit breaker is turned on. If the refrigerant leak detection sensor detects the
refrigerant leak, a fan automatically rotates even while an air conditioner stops. Be careful not to be injured by the fan.
• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.

Remote controller wiring
For this indoor unit, a remote controller (RBC-AMS55E*) is built into the unit.
"L" (length of remote controller wiring) is 2.5 m.
Remote controller wiring, remote controller inter-unit wiring
Total wire length of remote controller wiring and remote
controller inter-unit wiring = L + L1 + L2 + ... Ln
Total wire length of remote controller inter-unit wiring = L1 + L2 + ... Ln
CAUTION
• The remote controller wire and Indoor / Outdoor connecting wires cannot be parallel to contact each other and cannot
be stored in the same conduits. If doing so, a trouble may be caused on the control system due to noise or other
factor.
• For Floor standing type, remote controller is built in. When the units are used as simultaneous operation system, up
to two remote controllers of Master and Sub remote controller can be connected. When there are three remote
controllers or more in the system, remove connector connecting to the terminal block (A/B) in the Indoor unit for
remote controller other than Master or Sub remote controller. Set the Master and Sub of remote controller according
to the separate Installation Manual for remote controller.
