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.
● For the equipment that uses a three-pin socket, ensure that the ground
terminal in the socket is connected to the protective ground point.
● If high touch current may occur on the equipment, ground the protective
ground terminal on the equipment enclosure before connecting the power
supply; otherwise, electric shock as a result of touch current may occur.
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
specications.
● 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 routed into 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 dierent types,
ensure that they are at least 30 mm away from each other.
● 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 backll area are in close contact with the ground to prevent
cable deformation or damage during backlling.
● 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.
