THE ALPHA CFR
IMPORTANT SAFETY PRECAUTIONS
Carefully unpack the unit. Report any shipping damage immediately.
Please read the operators manual. If you have any questions regarding the safe
installation of the unit, contact Alpha Technologies.
The unit should be serviced only by qualified personnel.
The unit contains more than one live circuit. Even though AC is not present at the
input, it may be present at the output.
Always switch the battery circuit breaker to off before connecting or disconnecting an
external battery pack. This greatly reduces the chance of spark.
For units with a detachable AC line cord, connect a dedicated grounding wire (14 AWG/
2.0 MM
2 ) from the ground lug on the back of the unit to an electrical ground point. This
will provide a safety ground connection to the unit and all of its attached equipment,
even when the AC line cord is unplugged.
The connections on the back of this unit are not for use with telephone network
connections.
The standard unit, with line cord and receptacles, may be installed by a non-technical
user.
Units equipped with terminal block input or output connectors, or external battery
packs, must be installed by qualified service personnel in accordance with the following
table:
MODEL TERMINAL BLOCKS TIGHTENING TORQUE
AWG mm 2 Inch Newton
Pounds Meters
1500-2500 (60Hz) 14 2.0 35 4.0
3000 (60Hz) 12 3.0 35 4.0
2000-3000 (50Hz) 16 1.5 35 4.0
When not in service, the batteries should be charged at least once every three months
to ensure optimum performance and battery life. For standard units, simply plug the
units’ power cord into a wall receptacle and leave it running for one to three days.
The unit should be installed upright in a well ventilated area that is free of dust and
moisture.
Alert Fire or Emergency personnel than an uninterruptible power supply is installed in
the building by placing a notification or warning label on the electrical panel.
When connecting a load to the unit’s rear panel, do not exceed the output rating of the
unit.
