North American Regulatory Information

Business Communications Manager equipment meets all applicable requirements of both the CSA

C22.2 No. 950-95 and UL-1950 Edition 3.

Danger: Risk of shock.

Read and follow installation instructions carefully.

Ensure the Business Communications Manager and Business Communications Manager

expansion unit are unplugged from the power socket and that any telephone or network

cables are unplugged before opening the Business Communications Manager or Business

Communications Manager expansion unit.

If installation of additional hardware and /or servicing is r equire d, disc onnect all tele phone

cable connections prior to unplugging the Business Communications Manager.

Ensure the Business Communications Manager and Business Communications Manager

expansion unit are plugged into the wall socket using a three-prong power cable before any

telephone cables are connected.

Caution: 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 ne cessary 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 wit h a thi rd-wire ground.

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 Pro tective Earth ground 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 (central office lines) removed first.
