SAFETY
ELECTRICAL SAFETY
HIGH VOLTAGE
Some components of the power system operate with high voltage. Direct or indirect
contact with these components through non-insulated protective material poses a fatal
hazard.
The installation of AC power supply equipment must comply with safety regulations, and personnel carrying out
the installation of AC equipment must be qualied in high voltage AC-power operation.
It is strictly prohibited to wear watches, bracelets, rings or other conductive objects on your wrist or hand.
Turn off the power immediately if you nd water or moisture in the electric cabinet. When operating in humid
conditions, water should be strictly prevented from entering the equipment.
A “Do not operate” sign must be hung on switches and buttons that are not to be used during installation.
Construction of high-voltage lines can cause re or electric shock accidents.
The racking and wiring of AC cables through the area must comply with the local
regulations and specications. Only personnel qualied for high-voltage and AC
operations can carry out various high-voltage operations.
TOOLS
Special tools must be used for all high AC voltage operations.
THUNDERSTORMS
High AC voltage operations during thunderstorms are strictly prohibited.
Strong electromagnetic elds are produced in the atmosphere during thunderstorms. To avoid lightning
damage to equipment and personnel, do not carry out any operations during thunderstorms.
ELECTROSTATICS
Static electricity generated by the human body can damage electrostatic-sensitive
components on boards such as large-scale integrated circuits (ICs). To prevent static
damage to sensitive components, personnel must wear an anti-static bracelet when in
contact with equipment (hand-held boards, circuit boards, IC chips, etc.). The anti-
static bracelet must be well-grounded on the other end.

SAFETY
SHORT CIRCUITS
It is strictly prohibited to short-circuit the power supply system to the positive and
negative poles or to short the non-ground pole to ground during operation. Short
circuits can cause equipment to burn and pose a personal safety hazard.
In addition, the polarity of the cables and interface terminals must be strictly checked when carrying out live
work.
Power distribution operation space is limited. Before any operation, close attention must be paid to the choice
of operating space.
An insulation tool must be used during operation.
When working with electricity, care must be taken to keep your hands, wrists and arms steady, to prevent
accidents from a tool slipping, or from too much movement of a tool or your body.
SHARP CORNERS
When moving equipment by hand, wear protective gloves to prevent cuts.
POWER CABLE
Make sure that the cable label is correct before connecting the cable.
SIGNAL LINE
The signal cable should be tied separately from the power cable and at
least 15mm away.
