To Configure the
Trace UR-UPS
(continued)
Setting AC Transfer Sensitivity (JP1 - BROWNOUT)
The Transfer Sensitivity jumper sets the voltage limits
which the AC input voltage can fall or rise to before the
unit switches to the battery (or batteries) to power the
load.
Refer to Table 2-1, on page 10, for the AC transfer
voltage ranges of the Trace UR-UPS.
Two settings are available: GEN for generator supplied
power, and UPS (default) for utility supplied power.
Since some generators may have wide fluctuations in the
output voltage, selecting GEN MODE allows the range of
acceptable voltage to be from 90–140 Vac before the unit
switches to batteries. In the UPS MODE, the tolerance for
utility supplied power is from 105–130 Vac.
To Select UPS MODE (Default) (105 - 130 Vac)
• JUMPER ON: Place the jumper on both contact pins.
To Select GEN MODE (90 - 140 Vac)
• JUMPER OFF: Remove the jumper from the contact pins
and place it over only one of the pins. This will keep the
jumper available for future use.
Figure 2-6
Setting AC Transfer Sensitivity (JP1)
To select UPS MODE,
leave the jumper ON
(This is the default configuration.)
To select GEN Mode,
take the jumper OFF and place
it over only one pin.
WARNING:
CHANGING
CONFIGURATION
SETTINGS
REQUIRES ALL
SOURCES OF
POWER (AC AND
DC) BE
DISCONNECTED
FROM THE TRACE
UR-UPS.
NOTE: This unit requires
a well-regulated
generator for
optimal
performance.
NOTE: Transfer time from
utility to inverter is
approximately
8-10 milliseconds
with the loss of
grid power.
