Installation, operation, and maintenance must be performed in the sequence
specified in the manual. Do not change the structure or installation sequence
of the equipment without permission.
When installing the equipment, use a torque wrench with a proper 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
specified value.
Before installing or removing power cables, ensure that the switch is turned
off.
If the equipment has multiple inputs, disconnect all the inputs before
operating the equipment.
Before connecting power cables, check that cable labels are correct and cable
terminals are insulated.
A circuit breaker equipped with a residual current device (RCD) is not
recommended.
It is recommended that the three-phase loads be equalized and the neutral-
ground voltage be kept at less than 2 V to meet power distribution
requirements.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits
to telecommunication network voltage (TNV) circuits.
A damaged cable must be replaced by the manufacturer or professionals to
avoid risks.
Check equipment connections periodically, ensuring that all screws are
securely tightened.
Do not use water to clean electrical components inside or outside of a
cabinet.
Do not scrawl, damage, or block any labels or nameplates on the equipment.
Promptly replace warning labels that have worn out.
For the equipment that needs to be grounded, install the ground cable first
when installing the equipment and remove the ground cable last when
removing the equipment.
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.
If a "high electricity leakage" tag is attached on the equipment, ground the
protective ground terminal on the equipment enclosure before connecting the
AC input power supply; otherwise, electric shock as a result of electricity
leakage may occur.
Do not operate the equipment in the absence of a properly installed ground
conductor.
