1.1 Overview
This UPS series is a double conversion system with sinewave output. It supplies
continuous, stable, clean power for commercial and industrial environments. When the
utility is lost accidentally, the UPS system will use the power from battery to output
without interruption.
This system is applied an advanced digital controller to control the double conversion
system, and with an isolated transformer at the output to protect the load and the UPS
itself. The UPS is also built-in user-friendly LCD interface and multiple communications
including Modbus, RS-232 and intelligent slot. With free download software, this UPS
provides complete power solution of monitoring and controlling remotely.
1.2 Basic structure
The whole system consists of REC module, INV module, static bypass, maintain bypass
and battery controller. The output of the UPS are switched over to either line input or
bypass input with two SCRs operated in parallel. The basic structure is shown as below:
1.3 Working mode
This part will introduce the working mode of the UPS system.
1.3.1 Line mode
When the UPS is working in line mode, the AC input will be rectified by REC module, and
then be converted to the output via INV module. Meanwhile, the battery is being
charged. At this time, static bypass is in standby.

When the utility fails, the UPS will transfer to battery mode without interruption. The
UPS converts the power from battery to output. At this time, static bypass is still in
standby. If the utility is recovered, the UPS will transfer back to line mode again.
1.3.3 Static bypass mode
Bypass mode can be enabled or disabled by user setting. The default setting is enabled.
The UPS system will work in bypass mode when the following conditions occur.
The UPS system doesn’t turn on.
The UPS is overload in line mode.
The rectifier or inverter module is abnormal.
The utility fails and the battery is discharged to low level.
When above mentioned situation is eliminated, the UPS will transfer back to line mode or
battery mode.

1.3.4 ECO MODE
ECO mode can be enabled or disabled by user setting. The default setting is disabled. If
it’s required to have high efficiency performance instead of the high power quality, it’s
better to enable “ECO mode”.
In this mode, load will be supported via Bypass input when utility quality is OK. And the
Line input will still be operated to charge battery and INV module is in standby status
with switch opened. When Bypass input is lost, the system will transfer to line mode or
battery mode. When Bypass input is restored, the system transfers back to bypass mode
again. This ECO mode operation greatly improves system efficiency.
1.3.5 Maintain bypass mode
When the UPS needs maintenance and load needs uninterruptible power, the users can
firstly transfer the inverter to bypass mode, and then switch on maintain bypass breaker.
After that, switch off all other breakers and switches. In this condition, the utility can still
power the load and users can maintain the UPS.

1.3.6 Other modes
Except mentioned modes above, there are standby mode, power-off mode and fault
mode.
There is no output in standby mode, but the utility will charge battery. If the UPS stays
in standby mode for a while without utility and load connection, the UPS will transfer to
power-off mode. At this time, the UPS can’t be turned on by pressing ON button. Please
kindly wait for 5 minutes to allow UPS completely off itself. After 5 minutes, UPS can be
restarted by pressing ON button.
The UPS will transfer to fault mode if a fault occurs in the UPS. When some minor faults
occur, the UPS still can transfer to bypass mode if bypass input is available. When some
severe faults occur, it won’t be eliminated until the users restart the UPS.
1.3.7 Single/Dual input source
The line input and bypass input are separated routes in this UPS. Users can apply
different power sourced into these two input routes and set up a dual-input system.
Users also can connect the same power source to these two inputs. Once the utility fails,
no Line input and bypass input is available at the same time. Then, it will transfer to
battery mode.

2.1 Conventions and used symbols
Conventions used:
WARNING! Warnings identify conditions or practices that could result in personal
injury;
CAUTION! Caution identify conditions or practices that could result in damaged to the
unit or other equipment connected.

2.2 Safety instructions
WARNING! Before installing and using this equipment, read all instructions and
cautionary markings on the UPS and this manual. Store the manual where it can be
accessed easily.
WARNING! This manual is for qualified personnel. The tasks described in this manual
may be performed by qualified personnel only.
WARNING! This equipment must be installed by qualified person.
WARNING! An earth cable whose cross section should be the same as or greater than
the power supply cable has to be connected to the protective earth connection.
WARNING! Make sure the UPS is isolated and protective earth correctly connected at
installing and before operating the UPS.
CAUTION! This UPS should use for an IT distribution system.
CAUTION! The UPS’s output neutral is same as the input neutral(Non isolate type). For
the correct operation of the UPS, the input neutral cable should be connected. It may
cause power loss without input neutral.
CAUTION! Please transport the UPS with packaged from factory.
WARNING! Pay attention to the slope of the ground and surface to avoid fall down
when moving the equipment.
CAUTION! Use the foot shore to support the USP but not the wheel.
WARNING! This equipment is heavy. Do not lifte too heavy without help.

CAUTION! The UPS can only working on dry condition. Shut down the UPS if any liquid
flows into the UPS and dry it with absorbent cloth. Please use dry cloth when clean the
UPS.
CAUTION! Please charge the battery first if using the UPS for first time or no using the
UPS for a long period of time (6 months maximum).
WARNING! Never manipulate the equipment with wet hands.
CAUTION! To avoid a risk of fire and electric shock, make sure that existing wiring is in
good condition and that the wire is not undersized. Do not operate the Inverter with
damaged or substandard wiring.
WARNING! When the UPS shut down the power supply to the load because of EPO
signal trigger, the equipment has power supply yet. To shut down the equipment’s power,
please turn off all the input power.
WARNING! Authorized service personnel should reduce the risk of electrical shock by
disconnecting both the AC and DC power from the UPS before attempting any
maintenance or cleaning or working on any circuits connected to the inverter. Turning off
controls will not reduce this risk. Internal capacitors can remain charged after
disconnecting all sources of power.
CAUTION! Do not open, disassemble or modify the equipment yourself. It contains no
user-serviceable parts. Attempt to service this equipment yourself may cause a risk of
electrical shock or fire and will void the warranty from the manufacturer.
CAUTION! Shut down the UPS If any smoke or gas exhausts from the UPS.
WARNING! Battery circuit is not isolated; it is dangerous to touch any part of the
batteries.
CAUTION! When batteries are replaced, the complete battery set has to be replaced
8
and do not reuse faulty batteries.
CAUTION! Do not expose the batteries in a fire or to high temperatures. Batteries may
explode.
CAUTION! Batteries involve a serious risk for health and environment. Their disposal
should be done in accordance with the existing regulations.
WARNING! Under high temperature environment, the case of this equipment could be
hot enough to cause skin burns if accidentally touched. Ensure that this inverter is away
from normal traffic areas.
CAUTION! Use only recommended accessories from installer. Otherwise, not-qualified
tools may cause a risk of fire, electric shock, or injury to persons.
CAUTION! To reduce risk of fire hazard, do not cover or obstruct the equipment.
