● The UPS can be congured with a backfeed protection dry contact to work
with an external automatic circuit breaker, preventing the voltage from
owing back to input terminals over static bypass circuits. If the installation
and maintenance personnel do not need backfeed protection, paste labels on
external mains and bypass input switches, informing that the UPS is
connected to a backfeed protection card. Disconnect the backfeed protection
card from the UPS before operating the UPS.
● The upstream power distribution of the UPS should comply with IEC
60364-4-41.

Environmental Requirements
● 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 specications (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
inammable air can cause extreme danger. Strictly obey the operating
environmental requirements specied in related user manuals when using or
storing the equipment.
● Do not use the UPS in the following places:
– Environments that are close to ammable 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-conned 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
1.6 Cooling System Safety
High Temperature and Pressure
● 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.
Refrigerant Frostbite
Refrigerant leakage may cause frostbite. Take protective measures (for example,
wear antifreeze gloves) when handling refrigerant.

Storage and Recycling
● Do not store devices near a heat source or under direct sunshine.
● Keep devices away from re or high-temperature objects, especially devices
injected with pressurized nitrogen or refrigerant; otherwise, explosion or
refrigerant leakage may occur, causing personal injury.
● The sign indicates that the product cannot be disposed of with other
wastes that have a shell in European Union (EU) areas. To avoid environment
pollution and harm to human health, wastes must be classied and recycled.
This also promotes resource reuse. When recycling a device, ll in the device
information in the recycling collection system or contact your dealer for help.
The dealer can help you recycle devices in a safe and environment-friendly
way.
1.7 Battery Safety
Before installing, operating, or maintaining batteries, read the battery
manufacturer's instructions. Observe the safety precautions provided in this
document which are supplemental to the safety instructions provided by the
battery manufacturer.
D ANGER
Do not short-circuit the positive and negative poles of batteries. Battery short
circuits can generate high instantaneous current, which may cause battery
leakage, overheating, re, or explosion. To avoid battery short circuit, do not
maintain batteries with power on.
D ANGER
Do not expose batteries at high temperatures or around heat-generating sources,
such as high-temperature sunlight, res, transformers, and heaters. Battery
overheating caused by external heat sources may cause vent opening, leakage,
re, or explosions.
D ANGER
Protect batteries from mechanical vibration, collision, punctures, and strong
impact. Otherwise, the batteries may catch re.
