3.2 Connection to Main and Load
Follow all installation and safety instructions very carefully; failure to do so may cause hazardous
situations to personnel and equipment.
Ensure the main power voltage matches with UPS. (110V/220V)
For electrical installation, closely observe the nominal current rating of the source.
Check the equipment’s power requirement to prevent overloading situations.
Do not connect devices that draw either massive power shortly or half-wave rectified current - such
as hairdryer, vacuum cleaner, laser printer, and plotter.
Note
: Although you may use the UPS immediately, maximum back up time will not be available yet. It is
recommended to charge the batteries for a minimum of 8 hours before use.
Connect the input cable to the UPS and the other end to the mains. The battery will automatically
charge when connecting to the main power.
Connect the loads to the UPS; Ensure receptacles are connected firmly.
(Optional) To protect your telecom/internet system, use RJ45/RJ11 cable to install the input/output
cable with matching in/out jack.

Operation
Necessary information for the operation of the unit is covered in this chapter. Normally UPS runs
automatically, but on a few occasions such as just after installation, all procedures are described
herein.
4.1 General Description
As Line-Interactive UPS, it is capable of providing clean and stable power to your critical system. While the
UPS regulates and filters power fluctuation, it also keeps the battery charged for any emergency.
Automatic transformer regulates over and under-voltage power.
During a power failure, the UPS immediately provides backup power from the battery to support
your essential equipment.
Power transference is typically achieved uninterrupted within 4 milliseconds.
Line-Mode/Battery-Mode
UPS will operate in Line-Mode that supports power and charge battery while connected to power.
During a power failure, the UPS will switch to Battery-Mode, in which power is maintained from the battery.
In case of failure time exceed Battery-Mode duration, UPS will shut down until voltage return to prevent
battery discharge.
Diagnostic Test
While the advanced battery management system monitors the conditions of the batteries, it sends
early warnings if a battery replacement is needed. Diagnostic tests can be performed from the control panel.
4.2 System Configuration
The UPS device and battery make up the system. Depending on site and load requirements, certain
additional options are available as tailored solutions. Please consider the following when planning your UPS
system:
The total demand for the protected system shall dictate the output power rating (VA). When
measuring demand, please allow a margin for future expansion and calculation error.
Battery-mode duration needs dictate the battery size. If the load is less than the UPS nominal
power rating, then the actual backup time is longer.
