OPERATION
6.1.
LOAD SUPPORT
The UPS is designed to draw a maximum input current of 156 Watts (100W plus 56 Watts additional for fast
charge). The power supply connected to the UPS must support the load as well as the charging power for the
energy storage elements. Examples of input loads:
•
5.57A at an input voltage of 28 VDC (156W)
•
6.5A at an input voltage 24 VDC (156W)
•
3.57A at an input voltage of 28 VDC (100W)
•
4.17A at an input voltage 24 VDC (100W)
The charging time may be longer for the first charge cycle after the unit has been sitting unpowered for a long
period of time, due to total depletion of charge voltage on the ELDC cells. If the maximum load power listed is
exceeded, the UPS will automatically disable the output and transition into a minor fault state as described in
MOD LED, Section 7.1.1.
Note that the UPS Hold Time will be reduced as the ELDC cells age, but the minimum Hold Time will be
supported throughout the lifetime of the UPS. The estimated UPS lifetime is based on the operating
temperature of the UPS. Figure 6: DIN Rail Installation below shows the Estimated UPS Life with respect to the
operating ambient temperature of the UPS.

RESET
The UPS can be reset by using a standard #1 sized paper clip to depress the recessed Reset Button accessible
from the bottom of the unit. With the power “ON”, depress and hold the Reset Button until the LEDs turn
“OFF”. The LED initialization sequence begins after releasing the Reset Button. See Figure 5: Reset Button and
Serial Number for the location of the Reset Button.
6.3.
RESTORING FACTORY DEFAULTS
The user settable parameters can be restored to factory default values by using a standard #1 sized paper clip to
depress and hold the recessed reset button accessible from the bottom of the unit. Turn unit OFF. Depress the
button and hold while switching the power ON. Release the button after the LED turns off and the LED
initialization sequence starts. Refer to ETHERNET Section 5.1 for the list parameters and their factory default
values.
