Dangerous energy
Danger
Warning
The power system contains output exceeds 240VA, when installing into end system care must be taken that the output and
appropriate wire may not be touched.
Multi-power input
Danger
Warning
Prevent electric shock and dangerous energy. Even if the AC input power is cut off, there is still dangerous conductive parts
fed by battery existing.
Power supply cable
Notice
Notice
Make sure the cable and cable labels are in accordance with actual installation before cable connection.
Tools
Warning
Warning
In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used.
Thunderstorm
Danger
Danger
Never perform high voltage, AC, iron tower, or mast operations on a day with thunderstorms about.
In thunderstorms, strong electromagnetic field will be generated in the air. Therefore the equipment should be solidly
earthed in time to avoid damage by lightning strikes.
Static
Notice
Notice
The static electricity generated by the human body will damage the static sensitive elements on circuit board, such as
large-scale ICs, etc. Before touching any plug-in board, circuit board and IC chip, ESD wrist strap must be worn to prevent
body static from damaging the sensitive elements. The other end of the antistatic wrist strap must be solidly earthed.
Short circuit
Danger
Danger
During operation, never short-circuit the positive and negative poles of the DC distribution unit of the system or the
non-earthing pole and the earth. The power supply equipment is a constant voltage DC power supply. Short circuit will
result in equipment burning and endanger human safety.
