4. As accumulator batteries may contain potential electric shock and short-
circuit current danger, to avoid accidents that might be thus resulted, the
following warnings should be observed during battery replacement:
5. Do not expose accumulator battery to fire in order to avoid possible
explosion that might endanger physical safety.
6. Non-professionals are not allowed to open or destroy accumulator batteries
for electrolytes in batteries contain strong acid and other dangerous
substances which will cause damages to both human skins and eyes. Should
electrolytes come into any contact with human body unintentionally, rinse
with clean water and seek medical advice.

reliability of this product to some extent. Therefore, the product is not
suitable for performance in the following environment:
2. For long-term inaction, UPS (without batteries) should be kept in dry
environment with temperature ranging from -25-55°C . Before start-up,
ambient temperature should be brought back to 0 or above for a certain
period of time (above 2 hours).
A. Locations where temperature exceeds the maximum or goes below
the minimum temperature as required by technical specifications or
humidity is improper (temperature range: 0-40°C ; relative humidity
range: 20%-90%).
B. Locations where vibration and collision are constant;
C. Locations where metallic dusts, corrosive substances as well as salts
and inammable gases are present.
