•
The ACG1UBP provides 22 minutes of additional runtime typical (for a total of 26 minutes at
full load typical).
•
The ACG1UBP-C2 provides 14 minutes of additional runtime (for a total of 18 minutes at full
load).
To operate with either model, connect the male end of the cable to the connector on the back panel of
the UPS. Connect the female end to the connector on the ACG1UBP. This operation may be done
either when the unit is shut down (prior to power up), or when the unit is operating.
The
ACG1252XRBP
also has an internal fuse. The connector pins are not energized until connected
to the Rugged-UPS
TM
1252. The UPS cannot “cold start” with only the ACG1252XRBP – the UPS’s
internal battery pack or AC input power / optional external DC input must be present for added safety.

The ACG1252XRBP provides 15 minutes (typical) of additional runtime (for a total of 19
minutes at full load, typical).
To operate the ACG1252XRBP, connect the male end of the cable to the connector on the back
panel of the UPS. Connect the female end to the connector on the XRBP. This operation may be
done either when the unit is shut down (prior to power up), or when the unit is operating.
Operation
The UPS operates on AC external input power. In case of AC power failure, the DC input (if present) is
used as backup. If the DC power fails the internal battery pack is used as backup. The UPS only
operates on its internal batteries if AC external power source is unavailable and DC power is unavailable.
The internal battery pack allows for short term power backup in case of loss of external power which
allows the user to shut down the system being powered in an orderly manner.
Since operating without a battery pack will NOT supply any backup power if the primary power sources
should fail, careful consideration should be taken when operating the device without a battery pack and
connected to a viable external AC power source. This means the system being powered could not be
properly shutdown in the event of primary power failure.
The following are optional functions which may be performed while using the UPS.
Reset the Circuit Breaker
To reset the AC circuit breaker after it has tripped, first move the circuit breaker switch handle fully to OFF
and then move it to the ON position. If the circuit breaker trips repeatedly, refer to the troubleshooting
procedures.
NOTE:
Do NOT hold the AC circuit breaker in the ON position.
Battery Status
To verify the battery pack is fully charged to its present capacity simply disconnect ALL external power
except the battery and visually check the Battery Status Indicators on the front panel. If ALL five
indicators are ON, the battery pack is fully charged to its present capacity.
Note:
If any power (other
than the battery) is being supplied to the unit, ALL the Battery Status Indicators may be illuminated which
does NOT indicate the actual capacity left in the battery.
Audible Alarm
The audible alarm sounds in a variety of ways to indicate different alarms symptoms. These alarms are
associated with various status indicators.
