Read the installation instructions before you
connect the system to its power source.
Warning
Do not work on the system or connect or
disconnect cables during periods of lightning
activity.

To avoid electric shock, do not connect safety
extra low voltage (SELV) circuits to telephone

for short-circuit (over current) protection. Ensure
that a fuse or circuit breaker no larger than 120

on the phase conductors (all current-carrying
conductors).
