Huawei FusionDC1000A - Cooling System Safety; Battery Safety

● To ensure power supply to loads during UPS upgrade, set the output to
maintenance bypass mode. To avoid power failure or load damage, ensure
that the bypass input is within the specied power supply range.
● Exercise caution when manually shutting down the UPS inverter for
transferring to bypass mode, or when adjusting the UPS output voltage level
or output frequency. Doing so may
aect the power supply to equipment.
1.5.2 Cooling System Safety
High Temperature and Pressure
● 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.
● 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.
Recycling
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 sustainability. To recycle an old device, use a recycling
collection system or contact the supplier.
1.5.3 Battery Safety
D ANGER
Do not connect the positive and negative poles of a battery or battery string
together. Otherwise, the battery may be short-circuited. Battery short circuits can
generate high instantaneous current and releases a large amount of energy, which
may cause battery leakage, smoke,
ammable gas release, thermal runaway, re,
or explosion. To avoid battery short circuits, do not maintain batteries with power
on.
