Wired Remote Controller Installation
 Push the two hooks at the same time.
1. Push the two hooks at the bottom of your Wired Remote Controller at the same time, and then pull up the
front cover to separate it from the rear cover.
2. Arrange the power cable and the communication cable so that they t in the housing along the edges of the
rear cover.
• Insert a at head screwdriver into the square groove in the upper area of the
hook to disassemble it easily.

Wired Remote Controller Installation
4. Reassemble your Wired Remote Controller.
Wired Remote Controller Installation
• Align the controller with the upper groove rst, and insert it by turning it downward as
shown in the gure.
After assembly, check and conrm that no wires are stuck in the gap between the rear and
front cover.
• When installing a Wired Remote Controller by using a cable longer than 10m, you must install the communication
cable and the power cable separatery. (Electrical interference can cause your Wired Remote Controller to malfunction.)
• When installing your Wired Remote Controller on the wall, consider the size of the wire hole, and select a wire with
a proper thickness.
• Wire that is connectable to Wired Remote Controller PCB.
- If you install the Wired Remote Controller by reclaiming, install it according to U-terminal cable specication.
- If you install the Wired Remote Controller by using four pieces of PVC wire, remove the 30cm(12inch) of the
sheath of the cable and install it only with the four pieces of wires. (Recommended specication: AWG21)

• Screws on the PCB terminal must be tightened with less than 6N-cm tightening torque. If the tightening torque is
greater, it may damage the screw thread.
3. Using more than two screws, rmly ax the rear cover of the remote controller to the wall, and then connect
the power(V1, V2) and communication cables(F3, F4), making sure these cables have reasonable length,
to the terminal at the back of the cover.
