the total load level.
2) When connecting devices with inductive loads (such as a printer), the in-rush current should be calculated carefully to confirm it
meets the capacity of the UPS. Power consumption of such loads may cause an overload.
3) If the UPS is overloaded, the buzzer will beep twice every second.
4) In case of overload, remove non-essential devices immediately. It is recommended to have the total load connected to the UPS no
more than 80% of its nominal power capacity to prevent overload and ensure system safety.
5) If the overload time is higher than the acceptable time listed in Online mode, the UPS will automatically transfer to Bypass mode.
After the overload is removed, it will return to Online mode. If the overload time is higher than acceptable time listed in Battery mode,
the UPS will go to fault status. At this time, if the bypass is enabled, the UPS will supply power to the load via bypass. If the bypass
function is disabled or the input power is not within acceptable bypass range, it will cut off output directly.
4.4.4 Charging the batteries
1) After the UPS is connected to the utility power, the charger will charge the batteries automatically, except in Battery mode or during
battery self-test.
2) It is recommended to charge the batteries at least 10 hours prior to use. Otherwise, the backup time may be shorter than expected.

every second) to alert users that the battery is at low level and the UPS will automatically shut down soon. Users may switch off some
non-critical loads to disable the shutdown alarm and prolong the backup time. If there is no more load to remove, proceed to shut
down all loads as soon as possible to protect devices and save data. Otherwise, there is a risk of data loss or load failure.
2) In Battery mode, users can press the Mute button to disable the buzzer.
3) Backup time depends on both internal and external battery capacity.
4) Backup time may vary due to different environments, temperatures and load types.
5) When setting the backup time for the default value of 16.5 hours (16.5 is the default value because of value set #09 on page 17
of the LCD settings; the default value is 990 minutes, or 16.5 hours), the UPS will shut down automatically to protect the battery
after discharging 16.5 hours. This battery discharge protection can be enabled or disabled through the LCD control panel. (Refer to
section 4.7 for more information.)
4.4.6 Testing the batteries
1) To check the battery status when the UPS is in Online mode/Freq. Converter mode, you can press the “Test” button for the UPS to

• When the parallel system is turned on to work through the inverter, do not operate the maintenance switch of any unit.
4.5 Parallel UPS Operation (SVT20KX and SVT30KX)
4.5.1 Parallel system initial startup
Before initial startup, first ensure all of the UPS systems can be connected in parallel and have the same configuration.
1) Turn on each UPS to Online mode (refer to section 4.4.1). Then, using a multimeter, measure the inverter output voltage of each
phase for each UPS to confirm that the inverter voltage difference between actual output and setting value is less than 1.5V (typically
1V). If the difference is greater than 1.5V, calibrate the voltage by configuring the inverter voltage adjustment (refer to Program Codes
15, 16 and 17, in section 4.7) in the LCD setting. If the voltage difference after calibration remains greater than 1.5V, contact
Tripp Lite Technical Support for further assistance.
2) Calibrate the output voltage measurement by configuring the output voltage calibration (refer to Program Codes 18, 19, and 20,
section 4.7) in the LCD panel to ensure the difference between the real output voltage and the detected value of the UPS is less
than 1V.
3) Turn off each UPS (refer to section 4.4.7), then follow the wiring procedure in section 3.5.
4) Remove the metal cover to access the parallel communication ports on the UPS; connect each UPS one by one (maximum of three
units for parallel installation) with the parallel cable and shared current cable. Follow the parallel communication cable configuration
as shown in the figure below:
= Current Sharing Cables
= Parallel Cable
4.5.2 Turning a parallel system on in Online mode
1) Turn on the line input breaker of each UPS. When all UPS systems enter Bypass mode, measure the output voltage between two
UPS systems for the same phase to ensure the phase sequence is correct. If these two voltage differences are near zero, then all
connections are correct. If not, check to see if the wirings are connected correctly.
2) Turn on the output breaker of each UPS.
3) Turn on each UPS one at a time. The UPS systems will then enter to Online mode synchronously and the parallel system is completed.
4.5.3 Turning on the parallel system in Battery mode
1) Turn on the battery breaker and output breaker of each UPS.
Note: Do not share one battery pack in a parallel system. Each UPS must be connected to its own battery pack.
2) Turn on any UPS. A few seconds later, the UPS will enter Battery mode.
3) Then, turn on another UPS. A few seconds later, the UPS will enter Battery mode and add to the parallel system.
4) If there is a third UPS in the setup, follow the same procedure as outlined above. The parallel system is complete.
4.5.4 Adding a new unit to the parallel system
1) A new unit cannot be added to the parallel system when the whole system is in operation. The load must be powered off and the UPS
system shut down.
2) Make sure all UPS systems can be connected in parallel and follow the wiring instructions in section 3.5.
4.5.5 Removing a unit from the parallel system
There are two methods to remove a unit from the parallel system:
Method 1:
1) Press the “OFF” key twice, each time for more than 0.5 seconds. The UPS will enter into Bypass mode or Standby mode without output.
2) Turn off the unit’s output breaker and input breaker.
3) After the unit shuts down, turn off the battery breaker and remove the parallel cable and share current cables. Then remove the unit
from the parallel system.

4. Operation
Method 2:
1) If the UPS indicates a bypass abnormal error code, you cannot remove the UPS without interruption and must first power down the
load and the UPS system.
2) Make sure the bypass setting is enabled in each UPS, then turn off the running system. All UPS systems will transfer to Bypass mode.
Remove all the maintenance bypass covers and set the maintenance switches from “UPS” to “BPS”. Turn off all input breakers and
battery breakers in the parallel system.
3) Turn off the output breaker and remove the parallel cable and share current cable of the UPS to be removed, then remove the unit
from the parallel system.
4) Turn on the input breaker of the remaining UPS system(s). The system(s) will transfer to Bypass mode. Set the maintenance switches
from “BPS” to “UPS” and reattach the maintenance bypass covers.
5) Turn on the remaining UPS systems.

ATO
Parameter 2: Output Frequency
Set the output frequency. You may choose three options in Parameter 2:
50.0Hz: Output frequency is 50.0Hz.
60.0Hz: Output frequency is 60.0Hz.
ATO: If selected, output frequency will be decided according to the latest normal utility frequency. If
it is between 46Hz to 54Hz, the output frequency will be 50.0Hz. If it is between 56Hz to 64Hz, the
output frequency will be 60.0Hz. Automatic (ATO) is the default setting.
Parameter 3: Frequency mode
Freq. Converter mode has two options to choose from in Parameter 3:
CF: Set UPS to Freq. Converter mode. If selected, the output frequency will be fixed at 50Hz or
60Hz according to the setting in Parameter 2. The input frequency can range from 46Hz to 64Hz.
NCF: Set UPS to Normal mode (not Freq. Converter mode). If selected, the output frequency will
synchronize with the input frequency within 46~54Hz at 50Hz or within 56~64Hz at 60Hz accord-
ing to the setting in Parameter 2. If 50Hz is selected in Parameter 2, the UPS will transfer to battery
mode when the input frequency is outside 46~54Hz. If 60Hz is selected in Parameter 2, the UPS
will transfer to battery mode when the input frequency is outside 56~64Hz.
*If Parameter 2 is ATO, Parameter 3 will show the current frequency.
