Alpha Technologies CFR Intelligent Interface Device - Manual (Page 39)

UPS Front Panel Installation
The CFR UPS is designed so that upgrading from a Standard Interface
Device to an Intelligent Interface Device is as easy as removing the front
panel and plugging in the new unit. Power should be completely removed
before proceeding. Note: This should be performed only by qualified service
personnel.
1. Disconnect all loads from the OUTPUT receptacles on the UPS.
2. Switch the rear panel BATTERY circuit breaker(s) OFF.
3. Switch the UPS OUTPUT switch OFF. Disconnect the UPS from the AC wall
receptacle. If the unit is hardwired, switch the AC circuit breaker supplying
the UPS OFF and mark the circuit "Out of Service".
4. If an external battery pack is connected to the UPS, remove the connector.
5a.
CFR-600 / CFR 1000 / CFR 1500 / CFR 2000 / CFR 2500 -
Loosen the two (2) Phillips screws from the UPS front panel (in the lower grill).
Gently pull the lower edge forward until the screws clear the chassis.
Carefully lift the front panel straight-up until it clears the top edge of the
unit. Disconnect the 34-conductor ribbon cable from the center of the panel's
circuit board and set the entire assembly aside.
5b. CFR 3000, CFR 4000, CFR 5000 -
Loosen the single, captive fastener from the upper-rear panel and remove
the cover. Loosen the two (2) front panel retaining screws from the upper-
front panel. Slowly lower the front panel and remove the 34-pin ribbon
connector.
Low Battery Warning
LOW BATTERY WARNING, indicated by the "LOW BATTERY" and
"WARNING" displays, precedes LOW BATTERY SHUTDOWN. It indicates
that the batteries are approaching full discharge and that the load can no
longer be supported. Immediate steps should be taken to protect the load or
begin a smooth shutdown of all loads connected to the UPS.
Low Battery Shutdown
LOW BATTERY SHUTDOWN, indicated by the "LOW BATTERY,"
"WARNING" and "SHUTDOWN" displays, has the highest priority. This
indicates that the UPS was no longer able to support the load from battery
power and shutdown to prevent over-discharge damage to the batteries. If
an additional source of power (such as a generator) is available, it should be
used until AC Line power returns.
Alarms are displayed as they occur and are determined by their effect on the
continuing operation of the UPS. Alarms will continue to be displayed until
the condition has been corrected. In addition, an audible alarm will sound to
indicate the presence of an alarm condition. Audible alarms can be cancelled
by pressing the keypad's MUTE key.
