1. Safety and EMC instructions
All safety instructions in this document must be read, understood and followed.
1-1. Transportation and Storage
Please transport the UPS system only in the original packaging to protect against shock and
damage.
The UPS must be stored in the room where the temperature is well regulated. Ambient
temperature should not exceed 40°C.
1-2. Preparation
Condensation may form if the UPS system is moved immediately from cold to warm environment.
The UPS system must be absolutely dry before being installed. Please allow at least two hours for
the UPS system to acclimate the environment.
Do not install the UPS system near water or in moist environments.
Do not install the UPS system where it would be exposed to direct sunlight or nearby heat source.
Do not block ventilation holes on the UPS housing.
1-3. Installation
Do not connect appliances or devices which would overload the UPS (e.g. big motor-type
equipment)) to the UPS output terminal.
Place cables in such a way that no one can step on or trip over them.
Do not block air vents on the housing of the UPS. Ensure proper unit spacing of ventilation.
UPS came equipped with grounding terminal, in the final installation phase, connect grounding/
earthing wire to the external UPS battery cabinets or appropriate grounding terminals.
The UPS can be installed only by qualified maintenance personnel.
An appropriate disconnect device such as short-circuit backup protection should be incorporated
during installation.
An integral emergency shutoff switch which prevents additional load from the UPS in any mode
of operation should be implemented during the installation.
Secure the grounding/earthing wire before connecting to any live wire terminal.
Installation and Wiring must be in accordance with the local electrical laws and regulations.

1-4. Connection Warnings
•There is no standard backfeed protection inside of the UPS. However, there are relays on the Input to
cut off line voltage and while the neutral is still connect to UPS.

•This UPS should be connected with TN grounding/earthing system.
•The power input for this unit must be three-phase rated in accordance with the equipment nameplate. It
also must be suitably grounded.
•Use of this equipment in medical instrument of any life-sustaining equipment where failure of this
equipment can reasonably be expected to cause the failure of the life-sustaining equipment or to
significantly affect its safety or effectiveness is not recommended. Do not use this equipment in the
presence of a flammable mixture with air, oxygen or nitrous oxide.
•Connect grounding terminal of UPS to a grounding electrode conductor.
•In accordance with safety standard EN-IEC 62040-1, installation has to be provided with a《Backfeed
Protection》system, as for example a contactor, which will prevent the appearance of voltage or
dangerous energy in the input mains during a mains fault (respect the wiring diagram of «Backfeed
Protection» depending if the equipment is with signal or three phase input).
There can be no derivation in the line that goes from the «Backfeed Protection» to the UPS, as
the standard safety would be infringed.
•Warning labels should be placed on all primary power switches installed in places away from the unit to
alert the electrical maintenance personnel of the presence of a UPS in the circuit. The label will bear the
following or an equivalent text:
Before working on this circuit
-Isolate Uninterruptible Power Supply (UPS)
-Then check for Hazardous Voltage between all terminals including the protected
earth
Risk of Voltage Backfeed
WARNING
HIGH LEAKAGE CURRENT
EARTH CONNECTION ESSENTIAL
BEFORE CONNECTING SUPPLY

1-5. Operation
Do not disconnect the grounding/earthing conductor cable on the UPS or the building wiring
terminals under any circumstance.
The UPS system features its own, internal current source (batteries). The UPS output sockets or
output terminal blocks may be electrically live even if the UPS system is not connected to the building
mains/live wires. (only for standard models)
In order to fully disconnect the UPS system, first press the “OFF” button and then disconnect the
mains/live wires.
Ensure that no liquid or other foreign objects can enter into the UPS system.
The UPS can be operated by any individuals with no previous experience.

2. Installation and Operation
We also offer optional parallel function for both models upon request. The UPS with parallel function is called
the “Parallel model”. We have detail installation and operation procedure of the Parallel Model in the
following chapter.
2-1. Unpacking and Inspection
Unpack the package and check the package contents. The shipping package should contain:
● One UPS
●One user manual
● One monitoring software CD
●One RS-232 cable (option)
●One USB cable
●One parallel cable (only available for parallel model)
●One shared current cable (only available for parallel model)
NOTE: Before the installation, please inspect the unit. Be sure that there is no physical damage to the unit.
Do not turn on the unit and notify the carrier and dealer immediately if there is any damage or missing parts
and accessories. Please keep the original packaging for future use. It is recommended to keep each
equipment and battery set in their original packaging because they have been designed to provide maximum
protection during transportation and storage.

2-3. Single UPS Installation
Installation and wiring must be carried out in accordance with the local electric laws and regulations by
trained professionals.
1) Make sure that the mains wire and breakers of the building are rated for the capacity of the UPS to
prevent electric shock or risk of fire.
NOTE: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than
the UPS’s maximum input current. The receptacle may be damaged and destroyed.
2) Switch off the mains switch in the building before installation.
3) Turn off all the connected devices before connecting to the UPS.
4) Prepare wires based on the following table:

NOTE : The selections for color of wires should be followed by the local electrical laws and regulations.
5) Remove the terminal block cover at the rear panel of UPS. Then connect the wires according to the
following terminal block diagrams: (Connect the grounding/earthing wire first when making other wire
connections. Remove the grounding/earthing wire last when connecting the UPS!)
NOTE: For dual input model with single input power system, connect input terminals to the AC power
source and connect input and bypass input together (shows dashed line in below wiring diagrams)

NOTE 1: Make sure that the wires are connected securely with the terminals.
NOTE 2: Please install the output breaker between the output terminal and the load, and the breaker
should have leakage current protective function if necessary.
6) Put the terminal block cover back at the rear panel of the UPS.
Warning:
● Make sure a DC breaker or other protective device between UPS and the external battery pack is
installed for added safety. If not, please install it carefully. Switch off the battery breaker before
installation.
