1.6 Device Running Safety

The UPS is used for commercial and industrial purposes only. It cannot be used as

a power supply for life support devices.

For power supply systems that are critical to signicant economic interests or

public order, such as the national computing center, military command system,

emergency command center, railway signal system and control center, civil

aviation and air trac control center, airport command center, nancial clearing

center, and transaction center, the Tier 4 or 3 power architecture specied in

TIA-942 must be used. That is, two power supplies must be used to supply power

to loads.

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.

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.

NO TICE

● This is a category C3 UPS product for commercial and industrial application in

the second environment − installation restrictions or additional measures may

be needed to prevent disturbances.

● After unpacking the UPS, you are advised to power on the UPS as soon as

possible. If you temporarily do not use the UPS, take appropriate measures to

prevent moisture, dust, and foreign matter from entering the UPS.

● After unpacking batteries, you are advised to connect the battery supply as

soon as possible. If you temporarily do not use the batteries, store them in a

dry and clean environment. If batteries are stored for more than 90 days,

charge them in time. Otherwise, the battery lifespan may be aected.

● Install the UPS in an area far away from liquids. Do not install it under areas

prone to water leakage, such as air conditioner vents, ventilation vents, or

feeder windows of the equipment room. Ensure that no liquid enters the UPS

to prevent short circuits. Ensure that there is no condensation inside the

equipment or equipment room.

● If any liquid is detected inside the equipment, immediately disconnect the

power supply and contact the administrator.

D ANGER

● Do not expose the equipment to ammable or explosive gas or smoke. Do not

perform any operation on the equipment in such environments.

● During installation and maintenance, ensure that sundries do not enter the

UPS. Otherwise, equipment damage, load power derating, power failure, and

personal injury may occur.

If the valid mains voltage exceeds 320 V AC, the UPS may be damaged.

A UPS can be used to serve resistive-capacitive loads, resistive loads, and micro-

inductive loads. It is recommended that a UPS not be used for pure capacitive

loads, pure inductive loads, and half-wave rectication loads. A UPS does not

apply to regeneration loads.

Any operation on any electrical device 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 device.

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.

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,
