7.1. Installing the device behind a light switch
The installation process, tested and approved by professional electricians, consists of the
following simple steps:
Step 1 – Turn OFF the fuse:
• To prevent electrical shock and/or equipment damage, disconnect electrical power at the
main fuse or circuit breaker before installation and maintenance.
• Be aware that even if the circuit breaker is off, some voltage may remain in the wires —
before proceeding with the installation, be sure no voltage is present in the wiring.
• Take extra precautions to avoid accidentally turning the device on during installation.
