Installation Inside a Cabinet
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.
Installation at Heights
Working at heights refers to operations that are performed at least 2 meters above the ground.
Stop working at heights if the steel pipes are wet or other potential danger exists. After any of
the preceding conditions no longer exists, the safety director and relevant technical personnel
need to check the involved equipment. Operators can begin working only after obtaining
consent.
Issue 02 (2019-08-30)
Route and bind AC power cables, DC power cables, signal cables, and communications
cables separately.
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.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telecommunication network voltage (TNV) circuits.
Keep irrelevant people far away from the equipment.
Before operating the equipment, wear insulation shoes and gloves, and take measures to
protect your eyes. Remove conductive objects such as jewelry and watches to avoid
electric shock or burns.
Use insulated tools or tools with insulated handles.
Use wooden or fiberglass ladders when you need to perform live working at heights.
Do not place the equipment in an environment that has inflammable and explosive gases
or smoke. Do not perform any operation in such an environment.
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.
Do not use flammable materials such as paper and cotton to shield or cover the
equipment that is running. Otherwise, heat dissipation will fail and the enclosure will
deform, which can cause a fire.
Do not place the product in areas prone to water leakage, such as near air conditioner
vents, ventilation vents, or feeder windows of the equipment room.
