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 breaker which is easily accessible with building equipment's wiring.
Please be sure to use the supplied round crimping terminals when connecting wires to the power supply terminal block and
Super Link terminal block.
Please use demand input device, emergency stop input device and external timer input device comply with a relevant IEC Safety Standard.
Refer to the figure below for the terminal orientation.
