Before installing or removing power cables, ensure that the switch is turned
off.
Before connecting a power cable, check that the label on the power cable is
correct.
A damaged cable must be replaced by the manufacturer, service agent, or
professionals to avoid risks.
Only qualified personnel are allowed to perform high-voltage operations on
the equipment.
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.
Do not route cables behind the air intake and exhaust vents of the
equipment.
Ensure that cables meet the VW-1 or ZB and higher flame spread rating
requirements.
Bind cables of the same type together. When routing cables of different types,
ensure that they are at least 30 mm away from each other.
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.
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.
When selecting, connecting, and routing cables, follow local safety regulations
and rules.
