IV. ESD
Notice
The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale
ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist strap must be worn to prevent body static from
damaging the sensitive components. The other end of the ESD wrist strap must be well earthed.
V. Short circuit
Danger
During operation, never short the positive and negative poles of the DC distribution unit of the system or the non-grounding
pole and the earth. The power system is a constant voltage DC power equipment, short circuit will result in equipment
burning and endanger human safety.
Check carefully the polarity of the cable and connection terminal when performing DC live operations.
As the operation space in the DC distribution unit is very tight, please carefully select the operation space.
Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.
Insulated tools must be used.
In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free movement of
the human body and tool is reduced to a minimum.
VI. Dangerous energy
Warning
240VA, hazardous energy, keep off, no bridge connection. This converter contains outputs exceed 240VA, when installing
into end system care must be taken that the output and appropriate wire may not be touched.
Battery
Danger
Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery
connection method.
Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent
battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs,
thus causing equipment damage and short circuit of PCBs.
Before any operation on battery, pay attention to the following points:
Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist.
Use special insulated tools.
Use eye protection device, and take preventive measures.
Wear rubber gloves and apron to guard against electrolyte overflow.
In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery
upside down or slanted.
