● When installing the equipment, use a torque tool of a proper measurement
range to tighten the screws. When using a wrench to tighten the screws,
ensure that the wrench does not tilt and the torque error does not exceed
10% of the specied value.
● Ensure that bolts are tightened with a torque tool and marked in red and blue
after double-check. Installation personnel mark tightened bolts in blue.
Quality inspection personnel conrm that the bolts are tightened and then
mark them in red. (The marks should cross the edges of the bolts.)
● To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits
to telecommunication network voltage (TNV) circuits.
● After the installation is complete, ensure that protective cases, insulation
tubes, and other necessary items for all electrical components are in position
to avoid electric shocks.
● Before maintaining a downstream electrical device supply or power
distribution device, turn o the output switch of its power supply equipment.
● During equipment maintenance, attach "Do not switch on" labels near the
upstream and downstream switches or circuit breakers as well as warning
signs to prevent accidental connection. The equipment can be powered on
only after troubleshooting is complete.
● Before fault diagnosis and troubleshooting, take the following safety
measures: Disconnect the power supply. Measure the power. Install a ground
cable. Hang warning signs and set up fences.
● Check equipment connections periodically, ensuring that all screws are
securely tightened.
● Only qualied 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.
Grounding
● 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.
● Ensure that the protective ground point of the equipment is reliably
connected to the ground screw of the metal enclosure (ground resistance: ≤
0.1 ohm).
● Do not operate the equipment in the absence of a properly installed ground
conductor.
● Do not damage the ground conductor.

Cabling
● When selecting, installing, and routing cables, follow local safety regulations
and rules.
● The ame spread rating of cables should meet the UL 1581 VW-1 or IEC
60332-3-22 (ZB) or higher requirements.
● 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 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 dierent 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 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, which aects the current-carrying capacity and temperature
rise.
ESD
NO TICE
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-specic integrated circuits (ASICs), observe ESD
