Shanghai Pytes Energy Co., Ltd
⚫ Ensure that the grounding impedance of the equipment complies with local electrical
standards.
⚫ 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 work on the equipment in the absence of a properly installed ground
conductor.
⚫ Do not damage the ground conductor.
Cabling Requirements
⚫ 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.
⚫ 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 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,
