Signal cables must be bound separately from strong-current cables and high-voltage cables.
Laying Out Cables
When the temperature is low, a violent strike or vibrations may damage the cable sheathing.
To ensure cable safety, comply with the following requirements:
Cables can be laid, or installed, only when the temperature is higher than 0°C (32°F).
Handle cables with caution, especially at lower temperatures.
Before laying out cables that have been stored in temperatures lower than 0°C (32°F),
move the cables to an environment that is at the requisite ambient temperature. Store
them in this environment for at least 24 hours.
Do not drop the cables directly from the vehicle.
As the insulation layer of a cable may age, or be damaged from high temperatures,
ensure a sufficient distance between cables and the DC busbars, shunts, and fuses.
Cables prepared by the customer should be flame resistant. Cables must not be routed
behind the air exhaust vent of the cabinet. The air exhaust vent should not be blocked by
any object.
Before connecting a cable, ensure that the cable and cable label to be used meet the actual
installation requirements.
1.7 Information About Foreign Objects near UPS
Equipment Installation
The purpose of this note is to provide information and warnings about the potential risks of
the operational integrity of an installed UPS. These risks are caused by foreign objects in or
near the UPS modules and relevant auxiliary equipment/components.
These risks are particularly high if conductive materials have entered the UPS modules/units
or the channels in the relevant auxiliary equipment/components.
Potential risks include damage to installed UPS equipment and subsequent power derating
and power failure of loads at critical positions.
Huawei UPS uses the highest safety standard in equipment design to ensure that live parts are
not in contact with the exterior and that no foreign object will enter the equipment during
operation.
However, when the UPS baffle plate and cover are open and the electrical wiring terminals
are exposed by the electrical contractor/installation personnel who are setting up a power line
connection, it is almost impossible to ensure that no foreign object will enter Huawei UPS
during onsite installation.
It is common to have someone working in the same room as the UPS during onsite
installation. Sometimes some people may be working above the UPS and relevant auxiliary
equipment/components.
To avoid serious damage to the onsite operation, property hazards, and personal injury
including fatal injury, it is the responsibility of each equipment manager or construction
