If fault diagnosis and troubleshooting need to be performed after power-off,
take the following safety measures: Disconnect the power supply. Check
whether the equipment is live. Install a ground cable. Hang warning signs and
set up fences.
Check equipment connections periodically, ensuring that all screws are
securely tightened.
Only qualified professionals can replace a damaged cable.
Do not scrawl, damage, or block any labels or nameplates on the equipment.
Promptly replace labels that have worn out.
Do not use solvents such as water, alcohol, or oil to clean electrical
components inside or outside of the equipment.
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.
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.
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.
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 different 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.
