Introduction
Tripp Lite’s SMART1524ET and SMART1548ET line-interactive UPS Systems offer a
wide operating temperature range and provide constant and reliable backup power
to critical equipment in harsh environments, including outdoor equipment. The UPS
systems distribute utility power to connected equipment when input power is available
and is within valid UPS voltage limits. Automatic Voltage Regulation (AVR) is available
to stabilize output voltage to protected equipment. The UPS will switch to battery
backup power during utility power outages and extreme voltage fluctuations to keep
connected equipment running without interruption.
The maximum output capacity of the UPS system is temperature-dependent:

1600W: -40°F to 131°F (-40°C to 55°C)
1200W: 131°F to 167°F (55°C to 75°C)
1000W: 167°F to 176°F (75°C to 80°C).

1.1 Switch “ON” the battery circuit breaker.
The fan and all LEDs will illuminate momentarily. The LCD display will report
STARTUP, then the yellow ALARM LED will illuminate and a series of UPS status
notification screens will be available to view.
1.2 Switch “ON” the AC Input circuit breaker.
For approximately 30 seconds, the UPS will monitor AC input line power and turn
on if input is valid. The yellow ALARM LED will continue to illuminate. The LCD
may report the initial turn-on sequence as recovery from a power failure. Press
the ESC button to clear these notifications and view the main UPS status screen.
1.3 Switch “ON” the AC Output circuit breaker.
To power connected equipment, switch ON the AC output circuit breaker to enable
UPS output. You may need to press the ESC button to clear any notifications and
view the main UPS status screen.
2 Verify Battery Backup Operation

Note: Battery mode testing can be performed immediately after installation with a small test
load. For testing at higher loads, it is recommended the battery bank be allowed to charge
for 24 to 48 hours, or until the UPS reports 100% battery charge.
2.1 Switch the UPS from AC LINE POWER MODE to BATTERY MODE.
Switch OFF the AC input circuit breaker to simulate a power failure. The UPS will
continue to provide AC output and the LCD screen will report BATTERY MODE,
OUTPUT VOLTAGE and LOAD LEVEL PERCENTAGE.
Note: You may need to press the ESC BUTTON to clear any notifications resulting from the
loss of AC input before viewing status and measurement values on the main UPS status
screen.
2.2 Switch the UPS from BATTERY MODE to AC LINE POWER MODE.
Switch ON the AC input circuit breaker to return the UPS to AC line power mode.
The UPS will maintain the output load and the LCD screen will report NORMAL
MODE, OUTPUT VOLTAGE and LOAD LEVEL PERCENTAGE.
Notes:
• You may need to press the ESC BUTTON to clear any notifications resulting from restoring
AC input before viewing status and measurement values on the main UPS status screen.
• If the UPS keeps switching between inverter and line mode, turn on the AVR buck and
boost settings via LCD. If the UPS continues to switch between inverter and line mode
with AVR engaged, change the UPS SENSE TYPE setting from UPS to GENERATOR.

Storage and Service
Storage
To avoid battery drain, all connected equipment should be turned off and disconnected
from the UPS. Press the power button and disconnect the unit from AC power. Your
UPS will be completely turned off (deactivated) and will be ready for storage. If you
plan on storing your UPS for an extended period, fully recharge the UPS batteries every
3 months. Plug the UPS into a live AC outlet, and allow the batteries to recharge for 4
to 6 hours. If you leave your UPS batteries discharged for a long period of time, they
will suffer a permanent loss of capacity.
