The BCM main unit and expansion unit are each powered through an AC outlet. The voltage
required depends on the geographical location of the units.
All systems are initially set at the factory, based on the intended destination. You must check that
the voltage and wiring are correct for your system before you connect any of the units to the power
source. Incorrect power settings result in equipment damage.
Read the following warnings. You must protect yourself and the BCM system from possible
electrical shocks.
Warning: Use only qualified persons to service the system
The installation and service of this unit must be performed by service personnel with the
appropriate training and experience. Service personnel must be aware of the hazards of
working with telephony equipment and wiring. They must have experience in techniques
that minimize any danger of shock or equipment damage.
Danger: Electrical shock hazards
Electrical shock hazards from the telecommunications network and AC mains are possible
with this equipment. To minimize risk to service personnel and users, the BCM system
must be connected to an outlet with a third-wire ground. In addition, all unused slots must
have blank faceplates installed. The covers on all units must be in place at the completion
of any servicing.
