User Manual
General Requirements
Use dedicated insulated tools when performing high-voltage operations.
AC and DC Power
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.
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 or ZB flame spread rating requirements or
higher.
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.
