For safety reasons, please use the round crimping terminals with insulated sleeves for connecting all wires to the central control.
Please do the grounding work. Please do not connect earth line with gas pipes, water pipes, lightning rods and grounding line of
telephone.
Please do not turn on the power supply (local switch) until all of the work is completed.
Please wait at least two minutes after the indoor and outdoor units are turned on before turning on the power supply.
Except for the central control in the figure all of the components are obtained at the site (wires, switches, relays, power supply, lamps,
etc.)
Please be sure to build the circuit breaker which is easily accessible with building equipment’s wiring.
Pease be sure to use the supplied round crimped terminals when connecting wires to the power supply terminal block and Super Link
terminal block.
Before connecting the wires, remove the cover of the terminal block. After the work is completed, fix the cover of the terminal block as
before. The cover is used to prevent electric shock due to accidental contact.
Please use a gas meter or watt-hour meter, demand input device and emergency stop input device which comply with a relevant IEC
Safety Standard.

Note 1: When this central control is used, use a shielded wire for the Super Link signal wire. Ground both ends of the shielded wire.
(Please wire the ground of the central control at Ground position “b” of “System Wiring” in the diagram)
Note 2: If the indoor and outdoor units connected to the network are all compatible units with New Super Link, a total wire length of 1500m per line is
possible (maximum distance: 1000m). However, be sure to use a 0.75mm

wire diameter if the total wire length exceeds 1000m. For further
information, please contact your sales representative or dealer.
