Installation Personnel Requirement
Installation and maintenance personnel must be trained to perform operations
correctly and safely.
Personnel Safety
● A high-voltage power supply provides power for device operations. Direct
human contact with the high voltage power supply or human contact through
damp objects can be fatal.
●
Unspecied or unauthorized high voltage operations could result in re or
electric shock, or both.
● Ground a device before powering it on; otherwise, the human body and the
device are exposed to danger.
● Before performing operations on the power supply facilities, power
o these
facilities.
● Do not look into the optical port without eye protection when handling
optical
bers.
● To protect human respiratory organs and human eyes from dust, take
protective measures when drilling holes.
● When working at heights, prevent objects from falling down.
Device Security
● Keep an unpacked device upright and handle it with care when carrying it or
installing it into a cabinet.
● Use a ladder to lay out cables. Do not trample on a device.
● Wear an ESD wrist strap or ESD gloves when handling circuit boards.
Otherwise, the static electricity discharged from the human body may
damage the electrostatic sensitive components, such as large-scale integrated
circuits (LSIs) on the circuit board.
● Before operating the device, check the electrical connection of the device, and
ensure that the device is properly grounded.
Condensation Prevention
● Before installing the equipment, ensure that no condensation is on the
equipment. Otherwise, the equipment may fail to be powered on.
● If the indoor and outdoor temperature
dierence is 15°C or more, wait eight
hours after moving devices to the equipment and then install them.
● Generally, when the outdoor humidity is greater than 80% and the indoor and
outdoor temperature
dierence is greater than 5°C, condensation forms. In
highly humid weather, before installing a device or board, you are advised to
remove the package inside an equipment room and check whether
condensation forms as follows: Touch the surface of the device or board with
dry
ngers or ESD gloves to check whether water marks exist. If they do,
condensation forms, and the device or board must be kept in the equipment
room for 8 hours before being powered on.
