ESD
The static electricity generated by human bodies may damage the electrostatic-
sensitive components on boards, for example, the large-scale integrated (LSI)
circuits.

Ensure that cables of the same type are bound together neatly and straight
and that the cable sheath is intact. When routing cables of different types,
ensure that they are away from each other without entanglement and
overlapping.
When cable connection is completed or paused for a short period of time, seal
the cable holes with sealing putty immediately to prevent small animals or
moisture from entering.
Secure buried cables using cable supports and cable clips. Ensure that the
cables in the backfill area are in close contact with the ground to prevent
cable deformation or damage during backfilling.
If the external conditions (such as the cable layout or ambient temperature)
change, verify the cable usage in accordance with the IEC-60364-5-52 or local
laws and regulations. For example, check that the current-carrying capacity
meets requirements.
When routing cables, reserve at least 30 mm clearance between the cables
and heat-generating components or areas. This prevents deterioration or
damage to the cable insulation layer.
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 below 0°C must be stored at room temperature for more
than 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 affects the current-carrying capacity and temperature
rise.
NO TICE
When touching the equipment and handling boards, modules with exposed
circuit boards, or application-specific integrated circuits (ASICs), observe ESD
protection regulations and wear ESD clothing and ESD gloves or a well-
grounded ESD wrist strap.
