2. Important Safety Instructions (Save These Instructions)
SAVE THESE INSTRUCTIONS!
External DC Circuit Over current Protective Device
CAUTION!
To reduce the risk of fire, connect only to a circuit provided with DC 100
amperes for L10US, 120 amperes for L15US, 160 amperes for L20US maximum
branch circuit over current protection in accordance with the National Electric
Code, ANSI/NFPA 70”.
WARNING! When backfeed protection is needed by local area regulations and codes, please
note that it is not a part of the system design and you must install an external automatic
isolation device on site, in order to prevent dangerous voltage or energy in the input of the
isolation device. The device must be rated according to the system specifications and must
open within 15 seconds after the upstream power supply fails.
HAZARD! If those instructions are not followed it may cause death or serious injury.
A label of this text or equivalent text in your language, must be installed on the UPS, and on
the backfeed isolator protection if it is installed remotely from the UPS.
CAUTION! (UPS having Internal Batteries): Risk of electrical shock –Hazardous
live parts inside this unit are energized from the battery supply even when the
input AC power is disconnected.
CAUTION! (No User serviceable Parts): Risk of electrical shock, do not remove
cover. No user serviceable parts inside. Refer servicing to qualified service
personnel.
CAUTION! (Non-isolated Battery supply): Risk of electric shock, battery circuit is
not isolated from AC input, hazardous voltage may exist between battery
terminals and ground. Test before touching.
WARNING! (Fuses): To reduce the risk of fire, replace only with the same type
and size of fuse.
WARNING! Unit intended for installation in a controlled environment.

WARNING! Do not dispose of batteries to a fire, the battery may explode.
CAUTION! Do not open or damage the battery, released electrolyte is harmful
to the skin and eyes.
CAUTION! A battery can present a risk of electric shock and high short circuit
current. The following precaution should be observed when working on
batteries: remove watches, rings, or other metal objects, use tools with
insulated handles.
To reduce the risk of electric shock, disconnect the UPS from the main supply
before installing a computer interface signal cable. Reconnect the power cord
only after signaling interconnections have been made.
Servicing of batteries should be performed or supervised by personnel with
knowledge of batteries and the required precautions. Keep unauthorized
personnel away from batteries.
For Replacement of batteries located in a service access area:
1. Servicing of batteries should be performed or supervised by personnel
knowledgeable about batteries and the required precautions.
2. Risk of explosion if battery is replaced by an incorrect type. When
replacing batteries, replace with the same type and number of batteries or
battery packs.
3. CAUTION: Do not dispose of batteries in a fire. The batteries may
explode. Dispose of used batteries according to the instructions.
4. CAUTION: Do not open or mutilate batteries. Released electrolyte is
harmful to the skin and eyes. It may be toxic.
5. CAUTION: A battery can present a risk of electrical shock and high short
circuit current. The following precautions should be observed when working on
batteries:
•Remove watches, rings, or other metal objects.
•Use tools with insulated handles.
•Wear rubber gloves and boots.
•Do not lay tools or metal parts on top of batteries.

IB00, L20US-IB60, L20US-IB00 UPS
•Disconnect charging source prior to connecting or disconnecting
battery terminals.
•Determine if battery is inadvertently grounded. If inadvertently
grounded, remove source from ground. Contact with any part of a grounded
battery can result in electrical shock. The likelihood of such shock can be
reduced if such grounds are removed during installation and maintenance.
These UPS units are extremely heavy. Caution should be taken in moving and
positioning equipment. The instructions contained within this safety manual are
deemed important and should be closely always followed during installation
and follow-up maintenance of the UPS and batteries.
CAUTION!
The unit has a dangerous amount of voltage. If the UPS indicator is on, the
unit’s outlets may have a dangerous amount of voltage even when not plugged
into the wall outlet because the battery may continue to supply power.
Care should be taken to undertake installation indoors, free from electrically
conductive particles which are under temperature and humidity control, to
reduce the risk of electric shock.
It is best to disconnect the device using the power supply cord. Ensure that the
equipment is placed in a position near the outlet where easily accessible.
Except for replacing the batteries, all servicing on this equipment must be
carried out by qualified service personnel.
Before conducting any maintenance, repair, or shipment, first ensure that
everything is turned off completely and disconnected.
For additional safety instructions, see the Safety section of the Service Manual.

3. Main features
3.1. Summary
This series UPS is a kind of 3-phase input/ 3-phase output-out high frequency online UPS.
The UPS can solve most of the power supply problems, such as blackout, over-voltage,
under-voltage, voltage sudden drop, oscillating of decreasing extent, high voltage pulse,
voltage fluctuation, surge, inrush current, harmonic distortion (THD), noise interference,
frequency fluctuation, etc.
This UPS can be applied to different applications from computer device, automatic
equipment, communication system to industry equipment.
3.2. Functions and Features
3 Phase In/3 Phase Out UPS
It is 3 Phase In/3 Phase Out high-density UPS system, of which input current is kept in
balance. No unbalance problem might occur.
Digital Control
This series UPS is controlled by Digital Signal Processor (DSP); hence it increases reliability,
performance, self-protection, self-diagnostics and many more.
Battery is Configurable
The battery voltage of this series UPS is configured to 20 blocks.
Charging Current is configurable
Through the user interface, the user may set the capacity of the batteries as well as
reasonable charging current as well as maximum charging current. Constant voltage mode,
constant current mode or floating mode can be switched automatically and smoothly.
Intelligent Charging Method
The series UPS adopts advanced three-stage charging method—
•1st stage: high current constant current charging to guarantee to charge back to 90%.
•2nd-stage: Constant Voltage in order to vitalize battery and make sure batteries are fully
charged.
•3rd stage: floating mode.
This 3-stage charging method will extend life of the batteries and guarantee fast charging.

operational parameters, such as input/output voltage, frequency & load %, battery % and
ambient temperature, etc.
Intelligent monitoring function
Using the optional SNMP Card (optional for extra charge), you may remotely control and
monitor the UPS.
REPO function
REPO function (Remote EPO) is available in this series UPS.
3.3. System configuration
UPS device, external or internal batteries make up the system. Depending on the site and
load requirements of the installation, certain additional options are available for the solution.
Planning a UPS system, the following should be taken into consideration:
•The total demand of the protected system shall dictate the output power rating (VA).
Allow a margin for future expansion or calculation inaccuracies from measured power
requirements.
•Backup time required will indicate the battery size needed. If the load is less than the UPS
nominal power rating, then actual backup time is longer.
•The following options are available with extra charge:
•SNMP/WEB card
•Relay card
•Parallel connection
