Installion Procedures
1. Prepare Flush-Mounted Box
Before installing the Flush-Mounted Box, you can
fasten four screws on Flush-Mounted Box as shown in
Figure. This will make Flush-Mounted Box be mounted
on the wall more firmly and securely after grouting
foam concrete.
Use a Plug to connect Corrugated Tube to Flush-
Mounted Box. The corrugated tube allows cable and
wirings to pass through. The cable and wirings are Eth-
ernet cable, DC power, and Relay control.
