● When routing power cables, ensure that there is no coiling or twisting. Do not
join or weld power cables. If necessary, use a longer cable.
● Ensure that all cables are properly connected and insulated, and meet
specications.
● Ensure that the slots and holes for routing cables are free from sharp edges,
and that the positions where cables are routed through pipes or cable holes
are equipped with cushion materials to prevent the cables from being
damaged by sharp edges or burrs.
● 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.
● Ensure that cables of the same type are bound together neatly and straight
and that the cable sheath is intact. When routing cables of dierent types,
ensure that they are at least 30 mm away from each other.
● 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 aects the current-carrying capacity and temperature
rise.
ESD
The static electricity generated by human bodies may damage the electrostatic-
sensitive components on boards, for example, the large-scale integrated (LSI)
circuits.
● When touching the equipment and handling boards, modules with exposed
circuit boards, or application-specic integrated circuits (ASICs), observe ESD
protection regulations and wear ESD clothing and ESD gloves or a well-
grounded ESD wrist strap.
