Huawei ESS-240V12-7AhBPVBA04 - Grounding and Cabling

● To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits
to telecommunication network voltage (TNV) circuits.
● A damaged cable must be replaced by the manufacturer or professionals to
avoid risks.
● Check equipment connections periodically, ensuring that all screws are
securely tightened.
● Do not use water to clean electrical components inside or outside of a
cabinet.
● Do not scrawl, damage, or block any labels or nameplates on the equipment.
Promptly replace warning labels that have worn out.
Grounding
● For the equipment that needs to be grounded, install the ground cable
rst
when installing the equipment and remove the ground cable last when
removing the equipment.
● Ensure that the equipment is connected permanently to the protective
ground. Before operating the equipment, check its electrical connection to
ensure that it is reliably grounded.
● Do not operate the equipment in the absence of a properly installed ground
conductor.
● Do not damage the ground conductor.
Cabling
● When selecting, connecting, and routing cables, follow local safety regulations
and rules.
● Ensure that cables meet the VW-1 or ZB and higher
ame spread rating
requirements and comply with IEC 60332-1 and IEC 60332-3-22 standards.
● Do not route cables behind the air intake or exhaust vents of the equipment.
● If a cable is connected to the cabinet from the top, bend the cable in a U
shape outside the cabinet and then route it into the cabinet.
● Bind cables of the same type together. When routing cables of
dierent types,
ensure that they are at least 30 mm away from each other.
● When routing cables, ensure that a distance of at least 30 mm exists between
the cables and heat-generating components or areas. This prevents damage
to the insulation layer of the cables.
● When the temperature is low, violent impact or vibration may damage the
plastic cable sheathing. To ensure safety, comply with the following
requirements:
– Cables can be laid or installed only when the temperature is higher than
0°C. Handle cables with caution, especially at a low temperature.
– Cables stored at subzero temperatures must be stored at room
temperature for at least 24 hours before they are laid out.
● Do not perform any improper operations, for example, dropping cables
directly from a vehicle. Otherwise, the cable performance may deteriorate due
to cable damage, which
aects the current-carrying capacity and temperature
rise.
