4. Reassemble your wired remote controller.
• A lign 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 10 m(32.80 ft), you must install the communication cable
and the power cable separately. (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.
• If you install the wired remote controller by using two pieces of PVC wire, remove the 30 cm (12 inch) of the
sheath of the cable and install it only with the two pieces of wires. (Recommended specication: AWG20)
• Maximum distance for connecting communication and power cable : 100 m (328 ft).
•
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
communication and power cable [(F3,F4) or (3, 4)], making sure these cables have reasonable length, to the terminal at
the back of the cover.
