Installation of Remote Controllers
Precautions
Low-voltage circuit provision is used for remote control communication, and as such, the remote
control cable is subject to the low-power circuit provision of internal wiring regulations and
!
therefore it cannot be brought into direct contact with a high-voltage AC power line, or housed in
the same conduit tube as a power line.
