Notes (1) In case of previous SL, since SC‑SL3N is for connection of 3 Super Link systems, one unit of SC‑SL2N‑E can be connected to
each system.
(2) Number of units in combination as shown above is applicable to when the indoor units being controlled by each central control are
not duplicated. When controlling the same indoor units with a plural number of central controls, it may affect the allowable
number of indoor units for connection. For further details, please consult your dealr.

Definitions of new and previous Super Links (new and previous SL)
New Super Link (new SL): All units connected to the network are models compatible new Super Link (KXE6 or
later models. Central controll and I/F are “N” or later models.), and the SL setting is
unchanged from the shipment (“New” or “Auto”).
Previous Super Link (previous SL): Units that do not meet the conditions of new SL. When the equipment connected to
the network include even one unit of model earlier than KXE4 or not with new SL.
Setting of Note (3) is required.

For the relay attached with local signal input device, please use the relay whose smallest contact point (ON/OFF) current is less
than 4mA.
Caution
Please do not connect power supply line to other terminals.
Misconnection may cause damage of electrical component and burnout, which is very dangerous. Check the wiring
again before turning on the power.

(5) Installation work
Please install the central control after turning off the power for fear of electric shock. Please arrange or protect the wiring so that
excessive force is not applied to the electrical wires.
Be careful that you do not damage the PCBs when using a screwdriver and other tools. The PCBs can be damaged by static
electricity, and so be sure to discharge any static electricity accumulated on your body before starting the work. (Static electricity
can be discharged by touching the control board and other grounded parts.)
(a) Installation Place
Please install in an indoor location that is not exposed to electromagnetic waves, water, dust, or other foreign substances. The
operating temperature range of this product is from 0˚C to 40˚C.
Install in a location where the ambient temperature remains within the operating temperature range. However, if the operating
temperature range is exceeded, be sure to implement corrective measures such as installation of a cooling fan. Be aware that
continued usage of this central control outside the operating temperature range can result in operation problems.

-
4
-
(b) Space required for installation
The dotted lines show the installation opening section for installation on the control board (the dimensions are only an example).
1) In case of installing on the control board
Please be sure to lock the control board to protect persons from electric shock.Avoid usage of heat-retaining materials and
heat-insulating materials because these can result in heat buildup and adversely affect the operation of the central control.
2) In case of embedding in a wall
Please check that the sufficient space is available in the wall.If the temperature inside the wall exceeds 40°C, install the
central control on the control board.
Caution
Please do not install devices that can cause the ambient temperature to rise in the same control board. Also, do not install
multiple controllers in the same control board. These can cause heat to build up and result in false operation. If multiple
central control must be installed in the same control board, take corrective measures to ensure that the temperature in the
control board does not rise above 40°C such as by installing cooling fans.

(c) Installation procedure
1) In case of embedding in a wall, first,
embed the power supply wire, signal
wire, and electrical box.
Keep the power supply wire and
signal wire separated to prevent
malfunctions.
Caution
Please confirm the voltage of
power supply, and then connect
the common or 230V correctly.
2) Please remove the upper case with
the following procedure.
1 Remove the screw (M2.5) by
philips-head screwdriver. (Please be
careful not to lose the screw.)
2 Open it in the direction of 3
while pushing the upper part lightly.
3) Please connect the power supply
wire.

4) Please connect the grounding wire.
Connect the grounding wire for
power supply wire to “Ground 1” ,
connect the grounding wire for signal
wire to “Ground 2”.
5) Please fix the central control on
the Electrical box or the wall by
supplied 5pan-head screw
6) Please connect the signal wire
(A, B terminal)
7) Please do group setting by a precise
driver (For the details, please refer
to “(6) Control switch
selection” and “(7) Setting the
control target units”).
8) Please cover the upper case onto the
lower case and attach the case by
the screw.
(Follow the reverse procedure of
