Safety Instruction
1. Prohibition
1.1There is a high risk of electric shock from the UPS inside, so please don’t not open
or remove the casing or front panel unless it is operated by authorized technicians,
otherwise warranty becomes void as well.
1.2 Please contact and discuss with distributors before connecting the UPS to following
equipments
Medical equipments which have direct relationship with patients’ life
Equipments like elevators which may do harm to human beings
Similar equipments as mentioned above
1.3 Don’t dispose of the battery with fire so as to avoid explosion
2. Safety notice
1) Output of standard UPS reconfigured with internal batteries may be energized even
if the UPS input is not connected to the utility
2) Do disconnect the UPS input and make sure the UPS is completely off before
moving the UPS or reconfigured the connection; otherwise, there will be potential
electric shock.
3) For the sake of human being safety, please well earth the UPS before starting it.
4) Working environment and storage way will affect the lifetime and reliability of the
UPS. Avoid letting the UPS work under following environment for long time
Area where the humidity and temperature is belong the specified
range(temperature 0 to 40℃, relative humidity 5%-95%).
Direct sunlight and location nearby heat
Area which can be crashed easily
Area with erosive gas, flammable gas, excessive dust, etc.
5) Keep the ventilations in good conditions otherwise the temperature of components
inside UPS will be high and the component and UPS life will be affected.
6) It is forbidden to pour liquid or put any objects into the UPS.
7) Don’t use liquid extinguisher if there is a fire, a dry powder extinguisher is
recommended.

- 3 -
8) Battery life cycle will be shorter as environment temperature rise. Replacing battery
periodically can help to keep UPS in normal status and assure backup time required.
Battery replacement should be done by authorized technician.
9) Keep the UPS in a dry area or environment if it will not be free of operation for long
time. Storage temperature of UPS with internal battery is -20℃to 55℃.extended
backup model without internal battery is -40℃to 70℃.
10) Taking out the UPS or batteries from storage, it is recommended to connect them
with the utility for at least 12 hours per 3 months to avoid battery damage
11) Don’t open the battery, electrolyte inside will do harm to eyes and skin. Please use
plenty of clean water to wash if touching and go to see a doctor right away.

2 Installations
2.1 Unpack checking
1) Don’t lean the UPS when moving it out from the packaging.
2) Check the appearance to see if the UPS is damaged during the transport, do not
switch on the UPS if any damaged found and please contact the dealer.
3) Check the accessories according to the packing list and contact the dealer if
found any parts missing.
2.2 Installation procedure
2.2.1 Installation note
Put the UPS at flat place next to the equipment.
Keep UPS at least 20cm from wall or equipment or other object. Don’t block the
ventilation holes of the UPS front panel and bottom part, so as to keep the
ventilation in good conditions, avoid temperature of components inside getting high.
Keep the UPS away from high temperature, water, flammable gas, erosive gas, dust,
direct sunlight, explosive things
Don't lay the UPS outdoor
3P 125A/400V circuit breaker is required at the input and battery and 2P 125A/400V
is required at the output.
PDU is required to connect to the UPS output so as to weaken the affection between
loads
In order to fix the UPS, please lock its wheels by shifting the sheet on each wheel.
RCD load like computer ,linear load and small inductive load can be connected with
the UPS. Please contact dealer if other types of loads is required to connect.
For the sake of user and equipments, please betake correct power configuration.
Fig.2-1a Correct power configuration

Fig.2-1b Wrong power configuration
2.2.2 Installation
External battery connection (for extended model only )
1) Make sure battery quantity complies with the specs. Measure the voltage of
battery bank after finishing connection and the battery voltage should be around
240VDC. Don’t mix batteries with different capacity, manufacturers and don’t mix
brand new and old batteries, either.
2) The breaker onto battery cabinet should be off.
3) Take out the connection box and remove the cover of terminals, use multi-meter
to make sure there is no DC voltage at the battery terminals of UPS.
4) Connect battery pole with positive pole, negative pole and common pole to
battery connecter(BAT+,BATN,BAT-）, don’t reverse battery connection.
CAUTION
It is recommended to connect or replace battery after switching off the
system; don’t reverse battery connection when doing battery hot-swapping.
