Cable Routing and Connection

6. Connect the AC Electrical Power to the
Control Module
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, and
electric shock:
D All wiring must be done by a qualified electri-
cian.
D Ground the Horizon system by connecting the
electrical power cable to a true earth ground.
Wire the control module(s) into the facility's electrical
system. It is recommended that the system be wired to
a separate circuit breaker. This will help prevent acci-
dental shutdown of the system and make it easier to
power off the system when necessary. The system is
designed to remain powered-up continuously during
normal operation.
To ease system maintenance, install a switch for
turning off the power at each control module. Locate
the switches near each control module, but out of
reach from the floor to prevent accidental shutoff of
power to the control module.
Connect the power cable to the control module as
shown in Fig. 5.
