1.3 Environment Requirements
Do not expose the equipment to flammable or explosive gas or smoke. Do not
perform any operation on the equipment in such environments.
Do not store any flammable or explosive materials in the equipment area.
Do not place the equipment near heat sources or fire sources, such as smoke,
candles, heaters, or other heating devices. Overheat may damage the equipment
or cause a fire.

When selecting, installing, and routing cables, follow local safety regulations
and rules.
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
specifications.
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.
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.
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.
