This rack mount UPS has the power control and operating indicators located on the front panel.  

 

The ON and OFF buttons control the power to the outlets on the UPS.  They can be used as a 
master On/Off switch for the connected equipment.  The charger and communication circuits of 
the UPS remain operational as long as it is plugged into an acceptable utility power outlet. 

Power On 

 

Press and release the large, upper button labeled “l TEST” to supply power to the connected 
equipment.  The equipment is immediately powered while the UPS performs a self-test. 

Power Off 

 

Press and release the small, lower button labeled “0” to turn off power to the connected 
equipment. 

 

 

Whenever the UPS is plugged in and utility voltage is present, the charger maintains 
battery charge.

The 5-LED display on the left of the front panel shows the percentage of available power being 
used by the connected equipment (load).  The display shows the voltage level between the highest 
LED lit and the next higher value.  For example, if three LEDs are lit, the connected equipment is 
drawing between 50% and 67% of the UPS’s capacity.  If all five LEDs are lit, the connected 
equipment is drawing between 85% and 100% of capacity.  Thoroughly test your complete system 
to make sure that the UPS will not become overloaded.  In the graphic to the left, the load capacity 
threshold is listed next to the LED (these are not shown on the actual UPS).    

 

During the self-test, the UPS briefly operates the connected equipment on-battery.  If the UPS 
passes the self-test, it returns to on-line operation.  If the UPS fails the self-test it immediately
