4. Wiring
⚫Use the supplied round-type crimp-style terminals (large) when connecting wires to the power supply terminal block.
⚫Do not use any supply cord lighter than one specified in below.
- Ordinary tough rubber sheathed cord (code designation 60245 IEC 53)
⚫Do not turn on the power supply (power switch) until all of the work is completed.
⚫Wait at least two minutes after the indoor and outdoor units are turned on before turning on the power supply.
⚫Except for the accessories, all of the components are obtained at the site.
⚫Before connecting the wires, remove the cover of the terminal block.
After the work is completed, return the cover of the terminal block to its original position.
The cover is used to prevent electric shock from accidental contact.
⚫Perform grounding work. Wire the ground for the power supply to Grounding point (1), shown in the diagram for “3.4
Installation clearances”.
⚫Use the Wiring clamp beside the power LED to fasten the wires connected to the power supply terminal block.
⚫When pulling out wires from the enclosure, secure or cover the wires with conduit to prevent tension from being applied
to the terminals.
Superlink signal line
Shielded wire (2 core, 0.75 mm2- 1.25 mm2)
Max. 1000 m per line (Max. distance: 1000 m, Total wire length: 1000 m)
Wire the ground for the Superlink system to Grounding point (2), shown in the diagram for “3.4 Installation clearances”.
Note 1:
When the gateway is used, use a shielded wire as the Superlink signal wire. Ground both ends of the shielded wire.
Wire the ground of the gateway to Grounding point (2), shown in the diagram for “3.4 Installation clearances”.
Note 2: The communication protocol can be chosen from either of the following two types.
One is the conventional Superlink (denoted as previous Superlink below), and the other is the new Superlink.
Choose either the new or previous setting for Superlink. (See user's manual.)
Whether the actual connection network is the new Superlink or previous Superlink depends on the type of
connected indoor unit, outdoor unit, etc. Contact your sales representative or dealer for more information.
If the indoor and outdoor units connected to the network are all compatible with the new Superlink, a total wire
length of 1500 m per line is possible (maximum distance: 1000 m). However, be sure to use wire with a diameter
of 0.75 mm2 if the total wire length exceeds 1000 m. For further information, please contact your sales
representative or dealer.
Note 3: Be sure to use the supplied round-type crimp-style terminals (small) when connecting wires to the Superlink
terminal block.
Emergency stop line, gas meter or watt-hour meter line
Shielded wire 0.75 mm2- 1.25 mm2
For safety reasons, use the round-type crimp-style terminals with insulated sleeves for connecting all wires to terminal blocks.
Wire as shown below.
(1) Upper tier of terminal block
(2) Lower tier of terminal block
Please connect a gas meter or a watt-hour meter that satisfies the specifications below.
・meter with pulse transmitter
・meter with pulse width of 80 ms or more
The energy consumption calculated by this gateway does not conform to OIML, and there are no guarantees concerning the
results of the calculations.
For selecting the gas meter or the watt-hour meter, please refer to the technical manual.
