Refrigerant Frostbite
Refrigerant leakage may cause frostbite. Take protective measures (for example,
wear antifreeze gloves) when handling refrigerant.
Issue 02 (2022-07-30)
The UPS operating environment must meet the requirements for the climate
indicator, mechanically active substance indicator, and chemically active
substance indicator in ETSI EN 300 019-1 class 3.6.
Ensure that the equipment is used in an environment that meets the product
design specifications (including power grid, temperature, and humidity).
Otherwise, the equipment may become faulty, and the resulting equipment
malfunction and component damage are not covered under the warranty.
After unpacking the UPS, you are advised to power it on as soon as possible.
If the UPS is not in operation, take appropriate measures to prevent moisture,
dust, and foreign matter from entering the UPS.
Any operation on any electrical equipment in an environment that has
inflammable air can cause extreme danger. Strictly obey the operating
environmental requirements specified in related user manuals when using or
storing the equipment.
Do not use the UPS in the following places:
– Environments that are close to flammable or explosive materials, dust,
corrosive gases or dust, conductive or magnetic dust, abnormal vibration,
or collision
– Rooms or outdoor environments where temperature and humidity are
not controlled (with high temperature, low temperature, moisture, direct
sunlight, or heat sources)
– Non-confined environments near the ocean (0–3.7 km) and indoor or
semi-indoor environments where the temperature and humidity are not
controllable, such as simple equipment rooms, civil houses, garages,
corridors, and direct ventilation cabinets near the ocean; or houses with
only roofs, railway station platforms, gymnasiums, and aquariums
– Environments that are conducive for the growth of microorganisms such
as fungus or mildew
– Environments where rodents (such as mice) and insects exist
When maintaining or replacing components, pay attention to high-
temperature components (such as the compressor, refrigerant pipe, and
electric heater) to prevent scalds.
When maintaining or replacing components, pay attention to high-pressure
components (such as the compressor and refrigerant pipe) to prevent the
refrigerant system from being cracked or exploded due to misoperations.
