BCM50 Installation and Maintenance Guide
Wiring warnings
Please read the following warnings before you connect any telephone lines or extensions to the
BCM50 system:
Warning:
Electrical shock warning
The MBMs have been safety approved for installation into the expansion unit. It is the
responsibility of the installer and user to ensure that installation of the hardware does not
compromise existing safety approvals.
BEFORE YOU OPEN the main unit or expansion unit, ensure that the network
telecommunication cables are unplugged and the unit is disconnected from the ac power
source.
Station modules: The ports on these modules are meant to be connected only to approved
digital telephones and peripherals with the proper cables on a protected internal wiring
system.
Do not connect any telephones to wiring that runs outside of the building.
Read and follow the installation instructions carefully.
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.
Warning:
Leakage currents
Service personnel must be alert to the possibility of high leakage currents becoming
available on metal system surfaces during power-line fault events on network lines. These
leakage currents normally flow safely to protective earth ground through the power cord.
However, if the ac power is unplugged prior to disconnecting the cables from the BCM50
units, this hazard can occur.
System shutdown: You must disconnect the telephony and data networking cables from
the system before disconnecting the power cord from a grounded outlet.
System startup: You must reconnect the power cords to a grounded outlet before
reconnecting the telephony and data networking cables.
