Issue 04 (2021-01-05)
When routing cables, ensure that a distance of at least 30 mm exists between
the cables and heat-generating components or areas. This prevents damage
to the insulation layer of the cables.
Do not route cables behind the air intake and exhaust vents of the
equipment.
Ensure that cables meet the VW-1 flame spread rating requirements.
Bind cables of the same type together. When routing cables of different types,
ensure that they are at least 30 mm away from each other.
Ensure that all cables are securely bound. Route and bind cables so that they
appear neat and tidy and their cable sheaths are intact.
If an AC input power 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 the bending radius of each cable is at least five times the
diameter of the cable.
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.
When installing, operating, and maintaining the equipment, comply with the
ESD protection regulations and wear the ESD clothing, gloves, and wrist strap.
When holding a board, hold its edge without touching any components. Do
not touch the components with your bare hands.
Package boards with ESD packaging materials before storing or transporting
them.
To prevent fire due to high temperature, ensure that the ventilation vents or
heat dissipation system are not blocked when the equipment is running.
Ensure that there are no acid, alkaline, or other corrosive gases in the
installation place.
Do not place the equipment near heat sources or exposed fire sources, such
as electric heaters, microwave ovens, roasters, water heaters, furnace fire,
candles, or other places where high temperature may occur. Otherwise, the
enclosure will melt or the equipment will heat up, which can cause a fire.
Install the equipment in an area far away from liquids. Do not install it under
areas prone to condensation, such as under water pipes and air exhaust vents,
or areas prone to water leakage, such as air conditioner vents, ventilation
vents, or feeder windows of the equipment room. Ensure that no liquid enters
the equipment to prevent faults or short circuits.
Before installing the equipment into a cabinet, ensure that the cabinet is
secured and will not tilt or fall down due to loss of balance, which can cause
personal injury or equipment damage.
Do not expose the equipment to flammable or explosive gas or smoke. Do
not perform any operation on the equipment in such environments.
