To Configure the
Trace UR-UPS
(continued)
Setting Depth-of-Discharge (JP3 - LVD)
The DEPTH-OF-DISCHARGE jumper sets the battery
voltage for DEEP or SHALLOW discharge
.
In DEEP discharge mode, the unit continues to supply AC
output power to the load until the batteries have
discharged to 10.6 Vdc for one minute. This allows the
batteries to discharge almost completely. The unit’s run-
time will be longer in this mode and there will be fewer
charge/discharge cycles. DEEP discharge is the default
factory setting (jumper on).
In shallow discharge mode, the unit continues to supply AC
output power to the loads until the batteries have
discharged to 11.7 Vdc for a period of five minutes. This
causes less stress on the batteries resulting in longer
battery life. The unit’s run-time will be shorter in this
mode and the batteries will receive more charge/discharge
cycles.
To Select DEEP Depth-of-Discharge (Default)
• JUMPER ON: Leave the jumper on both contact pins.
To Select SHALLOW Depth-of-Discharge
• JUMPER OFF: Remove the jumper from both contact
pins and place it over only one of the pins. This will keep
the jumper available for future use.

Setting Depth-of-Discharge (JP3)
To select SHALLOW Depth-of-Discharge,
leave the jumper OFF and placed over only
one pin.
To select DEEP Depth-of-Discharge,
place the jumper ON the two pins.
(This is the default configuration.)
NOTE: DEEP discharge
will increase run
time but may
decrease battery
life.
