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.

1.4 Mechanical Safety
D ANGER
When working at heights, wear a safety helmet and safety harness or waist belt
and fasten it to a solid structure. Do not mount it on an insecure moveable object
or a metal object with sharp edges. Make sure that the hooks will not slide o.
WARNING
Ensure that all necessary tools are ready and inspected by a professional
organization. Do not use tools that have signs of scratches or fail to pass the
inspection or whose inspection validity period has expired. Ensure that the tools
are secure and not overloaded.
WARNING
Before installing equipment in a cabinet, ensure that the cabinet is securely
fastened with a balanced center of gravity. Otherwise, tipping or falling cabinets
may cause bodily injury and equipment damage.

WARNING
When pulling equipment out of a cabinet, be aware of unstable or heavy objects
in the cabinet to prevent injury.
WARNING
Do not drill holes into the equipment. Doing so may aect the sealing
performance and electromagnetic containment of the equipment and damage
components or cables inside. Metal shavings from drilling may short-circuit boards
inside the equipment.
General Requirements
● Repaint any paint scratches caused during equipment transportation or
installation in a timely manner. Equipment with scratches cannot be exposed
for an extended period of time.
● Do not perform operations such as arc welding and cutting on the equipment
without evaluation by the Company.
● Do not install other devices on the top of the equipment without evaluation
by the Company.
● When performing operations over the top of the equipment, take measures to
protect the equipment against damage.
● Use correct tools and operate them in the correct way.
Moving Heavy Objects
● Be cautious to prevent injury when moving heavy objects.
● If multiple persons need to move a heavy object together, determine the
manpower and work division with consideration of height and other
conditions to ensure that the weight is equally distributed.
● If two persons or more move a heavy object together, ensure that the object
is lifted and landed simultaneously and moved at a uniform pace under the
supervision of one person.
● Wear personal protective gears such as protective gloves and shoes when
manually moving the equipment.
● To move an object by hand, approach to the object, squat down, and then lift
the object gently and stably by the force of the legs instead of your back. Do
not lift it suddenly or turn your body around.
● Move or lift the equipment by holding its handles or lower edges. Do not hold
the handles of modules that are installed in the equipment.
