CAUTION:
To reduce the risk of electrical shock, ONLY install the UPS in a
temperature- and humidity-controlled indoor area, free of
conductive contaminants. Rick of electrical shock! (i) Hazardous
live parts inside the UPS are energized from the internal battery
supply, even when the AC input power is disconnected. (ii)
Battery circuit is not isolated from AC input. (iii) Hazardous
voltage may exist between terminals and ground. Test before
touching. Do not remove the cover as there are no user-
serviceable parts inside. Servicing should only be performed by
qualified service technicians.

Operation
Connect the UPS to AC utility power and allow a minimum
of 8 hours to charge the internal batteries.
Connect all the devices to be protected into the desired
receptacles.
Battery & Surge Receptacles: (All models)
Provides power to critical devices during a blackout
Surge Only Receptacles: (All models)
Provides spike and surge protection for devices that do not
require battery backup.
Load Shedding: (1000VA-2000VA models)
The outlets labeled “Load-Shedding” offer battery and
surge protection but can be independently turned off and
on using SentryHD software. The default setting for these
outlets will be “On”.
Press and hold the “POWER” button until the UPS sounds
one beep then release.

8
minutemanups.com | 800.238.7272
The UPS will initiate a five-second self-test to check the
internal systems and batteries.
If a fault or bad battery is detected, the UPS will sound an
alarm and an associated error code for the fault on the LCD
Display. Once the self-test is cleared the UPS will begin
providing power to connected devices.
Input Voltage Sensitivity Adjustment:
(1000VA-2000VA models)
The input voltage window of the Entrust-LG can be adjusted
if the UPS is transferring to battery mode due to
inconsistent utility power. With the UPS off and connected
to utility power, press and hold the Scroll button for 5
seconds. This change will alter the default nominal input
voltage range from 87VAC to 82VAC before UPS transfers to
battery mode. To return the setting to its factory default,
repeat the process by holding the Scroll button for 5
seconds with the UPS off but connected to utility power.
USB Charging Ports: (1000VA-2000VA models)
One each of a type A and Type C USB charging port are
located on the front panel of the UPS for a total of 15W of
DC power. Charging power is available when the UPS is
plugged in to utility power and powered on. It is also
available when the UPS is in either AC or Battery mode.
Surge Protection Ports: (All models)
The Entrust-LG series comes with both RJ45 and Coax surge
protection ports.

9
minutemanups.com | 800.238.7272
Use the input port for the connection from the source and
the output port to connect the protected devices. Use of
these ports are not required for the operation of the UPS.
USB Communication Port: (All models)
Use the USB port, with the included USB communications
cable, to connect to a computer if using Minuteman’s
SentryHD software, (available via download from: www.
minutemanups.com/minuteman-software-download-
center/), and follow the instructions in the software manual
for installation. SentryHD is not required for the operation
of the UPS.
