Safety Precautions

Before starting installation work, read the "Safety Precautions" thoroughly in order to ensure you carry out installation
●
correctly.
Safety Precautions are divided into "Warning
●
WARNING : Indicates a high possibility that serious injuries or death may occur if the unit is not installed correctly.
CAUTION : Indicates a possibility that serious consequences may occur depending on circumstances.
Please be sure to follow the instruction.
After completing the installation, carry out a test run to confirm that no abnormalities occur, and show customers how to
use the unit according to the User's Manual. Please ask customers to keep the Installation Manual on hand.
Please ask your dealer or relevant professionals to install the unit. Installing the unit by yourself may result in defects,
●
which may lead to electric shocks or fire.
Install the unit correctly according to the Installation Manual. If any of the installation steps are not followed, electric
●
shocks or fire may occur.
Be sure to only use the included accessories and specified parts when installing the unit. Otherwise, it may result in
●
electric shocks or fires.
The electrical work should be performed by qualified electrical engineer, according to <Electrical Standards>, <Local
●
electrical safety regulations> and wiring specification. If any of the installation steps are not followed, electric shocks
or fire may occur.
When wiring, ensure solid connection and fasten specified cables securely so that terminal connections may not be
●
subject to external force working on cables. Incomplete connection for terminal wiring may cause electric shock and
resultant fire.
Please perform grounding work.
●
Please do not connect the ground wire with gas pipes, water pipes, lightning rod and telephone ground wire.
Incomplete grounding work may cause electric shock.
Please do not install the central control at the following places.
●
1. Oil fog filled place, oil spraying and steamy location such as kitchen, etc.
2. The place where corrosive gas such as sulfur dioxide generates.
3. The location with machine that generates radio wave.
It may cause abnormality in the control system and abnormal running.
4. The location at risk of flammable gas leaking.
The place where volatile combustible substance such as paint thinner and gasoline exists.
By any chance the gas leaks and it accumulates around the equipment, it may cause ignition.

Electric Wiring

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 Superlink
●
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.

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.

Installation Place

Please install in an indoor location that is not exposed to electromagnetic waves, water, dust, or other foreign substances.
PJZ012D091A 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.

Space Required for Installation

<Opening Space for the Installation>
Create a hole in the wall as shown in the figure above.
Be sure to check the dimensions required to correctly install
the unit.
(1) In case of installing on the control box
• Please use the control box of the size of 300mm × 400mm × 120mm
or larger.
• Please be sure to lock the control box 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.
Caution
Please do not install devices that can cause the ambient
temperature to rise in the same control box. Also, do not install
multiple controllers in the same control box. These can cause heat
to build up and result in false operation. If multiple central control
must be installed in the same control box, take corrective measures
to ensure that the temperature in the control box does not rise above
40°C such as by installing cooling fans.
<Service space>
Front of the central control
500mm or larger
Bottom of the central control
100mm or larger
(2) In case of embedding in a wall
Be sure to use the attached installation brackets. Alternatively, you
can use SLA3R-BX for SC-SL3N. Please be sure to use for protecting
persons from the electric shock. Please check that the sufficient space is
available in the wall. When the inside of the wall is divided and have a
cavity, please create space more than 0.08m
If there is partition on the left, right, top and bottom of the central

Caution
● Do not connect power supply wire to another terminal block.
When you connect by mistake, damage and damage by fire of the
electric part are caused, and it is very dangerous.
Please check the wiring thoroughly again before turning on power.
● The demand signal input is configured for two points. To configure the
3 level setting, contact your sales representative or dealer.
Notice
Please choose the new or previous setting of Superlink (SL) in the display of the main unit. (See user's manual)
It is necessary to change if the connection network is for previous Superlink. Whether the real connection network is new Superlink or previous Superlink
depends on the type of connected indoor unit,outdoor unit,etc. Inquire the agents or dealers for more information.
When choosing the new Superlink Communication setting, 1 system wiring can connect up to a maximum of 128 units. Be sure to connect wiring to the Superlink
system 1. Be careful not to connect to the Superlink system 2 or 3, as the main unit will not be recognized.
Power switch
The power switch is lower front of the central control. After installation is completed, turn the power switch ON.
Note that the central control does not start up unless the power switch is turned ON.
(It is turned ON by factory default.)
Note
Please peel off the protection sheet of the screen when you pass the central control to the customers.
Before you mount the upper case, please peel off the sheet.
After checking the wiring and doing power switch operation, when the screen is not displayed, please contact
the shop where the central control was purchased. This product consists of the exclusive parts, and you can not
exchange the electrical equipment. Please do not disassemble other than what is stated in this instruction manual.
