(8) 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.

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.

(b) Space required for installation

Please choose one of two ways.

1) In case of installing on the control board

• Please use the control board of the size of 300mm

x 400mm x 120mm or larger.

• Please be sure to lock the control board to protect

persons from the 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 risea 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

When the inside of the wall is divided and have a cavity,

please create space more than 0.08m

. Refer to the table

below.

If there is no partition on the left, right, top and bottom

of the central control, please create a space that is

105mm or deeper.

When you cannot create the sufficient space or

thickness of the wall is above 15mm, please install the

central control on the control board.
