General Information
NOTE: Your Rugged-UPS

1252 Series device may or may not contain all the features
listed in this manual depending on your particular configuration.
Product Description
The Acumentrics Rugged-UPS1252 is specifically designed for worldwide deployment in harsh
physical and electrical environments. The Rugged-UPS1252 provides 1250VA of nominal 115VAC
output from an input of 80-265VAC 47-440Hz or 22-32 VDC (optional 20-32 VDC). This wide voltage and
frequency tolerance enables the rugged series to operate from generators in the field, or any international
power standard. This durable and versatile system contains advanced on-line technology to provide
highly reliable power back up and conditioning for the most sensitive electronic devices. Optional
shipboard models do not have output neutral tied to ground.
The Rugged-UPS1252 utilizes a unique FlowThru design which maximizes internal cooling while
sealing electronic components from the damaging effects of moisture, airborne particles, and other
contaminates in the operating environment.
The Rugged-UPS1252 is an ON-LINE Power Factor Corrected (PFC), Uninterruptible Power Supply
(UPS). This UPS accepts a wide range of voltage and frequency inputs to allow it to provide clean,
reliable AC power to sensitive electronic equipment. This true on-line, double conversion UPS continually
creates a pure sinewave AC output from a DC bus, thus protecting your equipment from surges, spikes,
brownouts, blackouts and noise.
The UPS is designed as a free-standing, self contained unit. It is supplied with adhesive-attached vinyl
bumpers on the bottom of the UPS chassis. Various fixed mounting points are provided on the chassis to
allow for tray, rail, or customer configured hard-mount systems.

Front Bezel
This section illustrates and describes the controls, indicators, ports, & connectors
NOTE: These are rotated on this model.
1. ON/OFF – Alarm Disable Switch
The self-centering toggle switch is capable of turning the Rugged UPSON, OFF, and disabling the
audible alarm. Hold the switch in the ON position for at least 5 seconds to supply power to the
Rugged UPSand enable the audible alarms. Briefly hold the switch in the OFF position to turn the
Rugged UPSoff. To disable the audible alarm, briefly hold switch for approximately 1 second in the
ON position while the Rugged UPSis on. The alarm cannot be disabled during initial start-up of the
device.
2. Fan Intake
The Fan Intake pulls air into the Rugged-UPS 1252to assist with the cooling of the system. Air is
exhausted through the rear outlet of the device. Ensure that both the fan intake and rear exhaust are
NOT obstructed so that the operation of the Rugged-UPS-1252 is not compromised.

3. Load Indicators
Measures and displays the load being applied to the Rugged UPS. When all five indicator lights
are illuminated a full load (1250 VA) is being applied to the Rugged UPS. When there are NO
indicators illuminated there is NO load being applied to the Rugged UPS.
4. Battery Status Indicators
Displays the charging level of the battery pack. When ALL five indicator lights are illuminated the
battery pack is fully charged to its present capacity and on external power. When battery pack
charge is near depletion, the last LED blinks and the alarm beeps one per second before low-battery
shutdown occurs.
When the UPS switches to internal DC, the battery pack charge decreases and fewer LED’s remain
illuminated and operating time becomes shorter.
5. On AC Line
This indicator is illuminated when the Rugged UPSis supplying power to the loads from the AC
connection source. This indicator will begin flashing during 80 VAC and 265 VAC operation to
indicate the operating point is close to tolerance. This indicator is NOT illuminated when the AC
source drops below 80 VAC causing the Rugged UPSto switch to external DC. If external DC is
unavailable the Rugged UPSwill switch to Internal DC.
6. On External DC
An isolated DC input of 22-32 VDC or optional 20 – 32V VDC volts allows for operation from vehicle
power.
7. On Internal DC
An audible tone briefly sounds and then the indicator illuminates when the unit is supplying power to
the loads from the internal battery pack.
8. Replace Battery
This indicator illuminates when the battery has reached the end of its usable life (battery voltage is
below 19.8 VDC). Momentarily holding the ON switch for one second, after replacing the battery, will
clear the “Battery Fault” indicator without turning the device OFF.
9. Overload
This indicator will remain illuminated and an audible tone will continuously sound when the Rugged
UPScapacity load is exceeded by the loads connected to the Rugged UPS.
10. Over Temperature
This indicator will remain illuminated and an audible tone will continuously sound when the Rugged
UPSinternal operating temperature has exceeded safe operating limits. The Rugged UPSwill
shut down if the condition persists.

Start-Up
Normal Start-up is starting with external AC and /or DC Power available to the UPS.
•Verify the UPS is properly connected and that external AC and/or DC power is applied to the
UPS.
•Verify the ground cable is attached.
•Turn the AC Circuit Breaker switch to ON.
•Hold the ON/OFF switch in the ON position for up to 5 seconds and then release the switch.
NOTE: If the electronics (e.g. capacitors) are fully discharged, failure to follow this step will
create a false failure.
•After 10 seconds has elapsed, verify the following indicators illuminate:
•Battery Status indicators are illuminated identifying a battery is present and appropriate charge
status when the device is operating on battery only.
•AC Line indicator will illuminate when AC source is present.
•DC Line indicator will illuminate when DC source is present.
•Load indicators are illuminated.
Start-up on Internal Battery Pack (cold starting): when NO External power is available, the UPS can be
started using its internal battery pack. If the battery pack is fully charged, the UPS will operate up to 4
minutes at full load typical.
•Hold the ON/OFF switch in the ON position for approximately 1 – 5 seconds and then release the
switch.
•To prolong the battery charge, turn on only those loads which are absolutely necessary.
•The “On Internal DC” indicator will be illuminated. Monitor the battery status via the Battery
Status indicators. Indicators identify the present capacity of the battery pack and the audible
alarm beeps twice every fifteen (15) seconds. As the charge on the battery pack depletes, the
battery status indicators will extinguish. An audible alarm will begin to sound every second with
the second to last indicator blinking and will continue until the last indicator is blinking indicating
the battery pack is nearly depleted and low-battery shutdown is imminent.
NOTE: To minimize the risk of arching on the battery connectors please be sure when inserting
or removing the battery pack that the unit has AC input connected.
NOTE: The battery indicators identify the charge status of the battery when operating on
battery ONLY. The battery capacity diminishes over time.
Extended Run
Modules
The Rugged-UPS
TM
1252 has optional extended run capability, using either the ACG1252XRBP (2U
high) or the ACG1UBP (1U high). Both modules are shipped with an extended run battery cable,
appropriate for the model being used.
There are two versions of the ACG1UBP. Both have 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 1U
Extended Run Battery Pack – the UPS’s internal battery pack or AC input power / optional DC input
power must be present for added safety. The LED Panel Indicator is illuminated when the unit is
charging / discharging, or when in stand-by mode.
