1.2 Electrical Safety
High Voltage
The device is powered by a high-voltage power supply. Direct or indirect contact (through
damp or conductive objects) with high-voltage power sources will result in serious injury
or death.
Non-standard and improper high voltage operations may result in fire or electric shocks.
High Leakage Current
Ground the device components and the general ground cable before powering the device on.
Ensure that the ground continuity requirements stipulated in IEC61439-1:2011 is met, and the
ground resistance is 0.1 ohm at most. Otherwise, personal injury or device damage may be
caused by high leakage current.
Cover the exposed parts of cables inside the device with PVC insulation tape and place them
in appropriate positions.
Power Cable
Do not install or remove power cables when the equipment is powered on. Transient contact
between the core wire of a power cable and a conductor may generate electric arcs or sparks,
which may start a fire or cause eye injury.
Turn off the power switch before installing or removing a power cable.
Verify that the label on the power cable is correct before connecting the cable.
To ensure safety, damaged power cables must be replaced by the manufacturer, the
manufacturer's service agent, or similarly qualified persons.
Ensure that the equipment has a mechanism for disconnecting from the main power
supply. Contact intervals must be provided between different levels so that a circuit can
be disconnected under class III overvoltage conditions. Cables for the mechanism must
be incorporated into the fixed wiring based on the wiring rules.
