Safety
Additional Safety Information
The following interfaces are classified as Telecommunication Network Voltage (TNV) circuits,
and may be connected to exposed plant:
• DTM interface
• WAN interface
• TCM Isolator
• ASM8+: The Nortel Networks ASM8+ I/O ports are designated as OPX. This product does
provide Telecommunications Ringing Voltages and can be configured to provide Voltage
Message Waiting Indicator (VMWI). Installation of this device and all connections to this
device must be performed by Qualified Installation Personnel who are aware of the hazards
associated with telecommunications wiring and are aware of the local regulations for
treatment of telecommunications wiring for OPX deployment.
WARNING!
Only qualified service personnel may install this equipment. The instructions in this
manual are intended for use by qualified service personnel only.
Risk of shock.
Ensure the Business Communications Manager base unit is unplugged from the power
socket and that any telephone or network cables are unplugged before opening the
Business Communications Manager base unit.
Read and follow installation instructions carefully
Only qualified persons should service the system.
The installation and service of this hardware is to be performed only by service personnel
having appropriate training and experience necessary to be aware of hazards to which
they are exposed in performing a task and of measures to minimize the danger to
themselves or other persons.
Electrical shock hazards from the telecommunication network and AC mains are possible
with this equipment. To minimize risk to service personnel and users, the Business
Communications Manager system must be connected to an outlet with a third-wire Earth.
Service personnel must be alert to the possibility of high leakage currents becoming
available on metal system surfaces during power line fault events near network lines.
These leakage currents normally safely flow to Protective Earth via the power cord.
Therefore, it is mandatory that connection to an earthed outlet is performed first and
removed last when cabling to the unit. Specifically, operations requiring the unit to be
powered down must have the network connections (exchange lines) removed first.
