Installation Method
ENGLISH
Installation Method
Installation
1) Loosen and remove two screws that secure the
product.
2) Position the rear case to the direction towards to the
connector for convenient cable arrangement.
3) Secure the rear case on the installation place using the
supplied fixing screws.
4) Remove knock out shapes on the rear case (4-sided)
according to the connector’s size and direction.
Installation manual 7
Installation Method
5) Connect the connection wires properly according to the connection method. (Refer to the instruction
and set-up description)
6) Set the switch according to the setting method. (Refer to the instruction and set-up description)
7) Tighten the fixing screws on the top and bottom of the case.
1. Install the product on flat surface and install anchoring screws at more than 2 places. Otherwise
the central controller may not be anchored properly.
2. Do not tighten anchoring screws too tightly. It may cause deformation of the case.
3. Do not deform the case at random. It may cause malfunction of the central controller.
