Do not connect or disconnect power cables with power on. Transient contact between the core
of the power cable and the conductor will generate electric arcs or sparks, which may cause
fire or personal injury.

If a "high electricity leakage" tag is attached on the equipment, ground the protective
ground terminal on the equipment enclosure before connecting the AC power supply;
otherwise, electric shock as a result of electricity leakage may occur.

Before installing or removing a power cable, turn off the power switch.

Before connecting a power cable, check that the label on the power cable is correct.

If the equipment has multiple inputs, disconnect all the inputs before operating the
equipment.

A circuit breaker equipped with a residual current device (RCD) is not recommended.

A damaged power cable must be replaced by the manufacturer, service agent, or
professionals to avoid risks.

High voltage operations and installation of AC-powered facilities must be performed by
qualified personnel.
Cabling

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.

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.

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.

When selecting, connecting, and routing cables, follow local safety regulations and rules.
ESD
The static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.
