DANGER:
Never let the operating temperature of the unit exceed the recommended maximum.
Do not block or cover the ventilation openings in the case.

DANGER:
Do not attempt to recharge batteries. The power unit recharges the batteries itself.
Any other recharging method may cause leaks of corrosive electrolyte or explosion.
Discard discharged batteries as soon as possible. Discharged batteries are more
likely to leak.
Do not store batteries in high temperature areas. Batteries stored in a cold
environment should be protected from condensation during storage and warming.
Batteries should be stabilized at room temperature prior to use after cold storage. Do
not install batteries if the manufacturing date on the label indicates that the batteries
are more than 6 months old.
1145B Power Supply
The 1145B power supply powers ISDN/DCP, terminal equipment, adjuncts, and
other customer-supplied external equipment. It supplies -48V, 200 W total and
supports 32 outputs. You can install one ISDN terminal or DCP adjunct per
output.
A manual switch on the distribution unit lets the user redirect reserve power to
outputs 1 to 32 so that all outputs get battery reserve power.
An optional 1149 battery and 1146 distribution unit provides uninterruptible -48
VDC power.

DANGER:
When operating power-supply equipment, you must follow basic safety
precautions to reduce the risk of fire, electric shock and personal injury.
