Safety
 
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 is unplugged from the power socket 
before installing the UPS device.
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 
UPS device 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.
