Installation (Electric) and Service Instructions
Safety Precautions
Before conducting installation or electrical work, be sure to carefully read these "Safety Precautions" and
follow them carefully.
The precautions given in this manual consist of specific "Warnings" and "Cautions". Be sure to follow these
precautions, as they provide important safety related information. The labels and their meanings are as
described below.
Warning This refers to a hazard or unsafe procedure or practice which can result in severe personal
injury or death.
Caution This refers to a hazard or unsafe procedure or practice which can result in personal injury or
product or property damage.
● Be sure to arrange installation at the dealer where the system was purchased or use a professional installer. Electric
shock or fire may result if an inexperienced person performs any installation or wiring procedures incorrectly.
● Carefully follow these Installation (Electric) and Service Instructions when installing the unit. Electric shock or fire may
result if the unit is not installed correctly.
● Electrical installation should be performed by qualified electrician, in accordance with the provisions of the Technical
Standards for Electrical Installations, local regulations for indoor wiring, and these Installation (Electric) and Service
Instructions. Be sure to use a dedicated electrical circuit. Insufficient electrical circuit capacity may result in electric
shock or fire.
● Use the specified cables for the electrical connections, and connect the cables securely. Fasten the cables securely so
that the cables will not exert force on the connection terminals. Insecure connections or fastening may result in
overheating or fire.
● The installation location may require the use of a circuit breaker. Failure to use a circuit breaker may result in electric
shock or fire.
● Install this unit to the location where general users cannot easily access (such as inside the control box).
● When performing electrical installation, discharge any accumulated static electricity to ground before touching the unit.
● Always use the system together with a remote controller or a system controller.

Always shut off the power supply (breaker) before installing or uninstalling.
(1) Power supply connection
Connection terminals
Connect the power supply to the commercial
power mains (100 to 240 V AC), using a dedicated
circuit. Connect the power supply lines to the L and
N power supply terminals (the power supply

(2) Signal connection
Power switch ● Do not run signal lines through the same
conduit as power supply lines, use the same
cable as the power supply, or run close to the
power supply lines (maintain at least 30 cm
separation, if cabled outside the control box).
● Do not run the LINK1 and LAN signal lines
through the same conduit, or run the signal lines
close together.
● Connect indoor and outdoor signals using 0.5 -
2.0 mm² two-conductor cable.

terminals
Secure the shielded cable to the metal plate with
a screw, as illustrated (apply one-line
grounding).
● Use LAN cables of Category 5 or higher.
● Be sure to attach the supplied ferrite core at one
end of the LAN cable (Web Interface side). Use a
cable tie to make sure the ferrite core stays in place.

Wiring procedure
● Inter-unit control wire (no polarity)
Use the shielded wire for inter-unit control wiring.
Connect signal terminals 0 and 1 (LINK1) to the
inter-unit control wire terminals of an indoor or
outdoor unit.
Make sure that power lines are not connected to the
inter-unit control wire terminals.
* If the power voltage is accidentally applied to the
inter-unit control wire terminals, the fuse will go
out to protect the board, but not in some cases.If this
happens, disconnect the power line, and connect
the inter-unit control wire to the spare U2 terminal.
(The other signal line can stay connected to the U1
terminal.) The spare U2 terminals are right next to
the main U2 terminals.
Use terminal 2 (LINK1-U2) instead of terminal 1
● LAN cable
Connect the LAN cable directly to the PC or to the
network hub.

Cautions regarding the design of the control box
1
External dimensions
80 185
Take the following into consideration when designing the control box:
(1) To ensure sufficient airflow for cooling, provide air vents (holes, slots, etc.) on
the upper, lower, left and right sides of the box, as shown in the figure below.
(Be sure not to clog the ventilation hole when setting.)Ensure that the
temperature inside the control box does not exceed 40°C.

Caution
● Mount the unit far away from potential noise sources.
● Do not mount the unit where it could get wet, or in
areas of high humidity.
● Do not mount the unit where it could be subject to
excessive vibration or shocks.
● Mount the unit inside a control box.
(1) Remove the tapping screw at the side of the LAN
connector and open the lid.
(2) Mount the controller unit to the control box using
the four supplied bolts, washers, and nuts.
(3) Replace the lid, and secure it with the tapping screw.

* It is possible to install the unit upside down.
(2) Keep the power and communications signal
lines as far apart as possible (at least 50 mm,
if cabled inside the control box) to reduce the
effects of electrical noise.
