High voltage power supply offers electric power for equipment operation. Direct contact or indirect 
contact (via damp objects) with high voltage and AC mains supply may result in fatal danger.

During installation of the AC power supply assembly, local safety regulations must be 
followed. The personnel who install the AC facility must be qualified for high voltage and AC 
operations.

Conducting articles, such as a watch, hand chain, bracelet and ring are prohibited during the 
operation.

When operation is performed in a damp environment, make sure that water is kept away from 
the equipment.  

 

Non-standard and improper high voltage wiring may result in fire and electric shock. Therefore, 
AC cable installation and wiring must follow the local rules and regulations. The personnel who 
perform high voltage operations should be qualified for high voltage and AC operations.  

 

 

The electrostatic (static electricity) generated by human body may damage the electrostatic-
sensitive components on the circuit board, such as large-scale integrated (LSI) circuits. 

 
The human body moving, friction on clothes, friction between shoes and the ground, holding 
ordinary plastic with hands, will generate a static electricity field that will remain with the human 
body for a long time. 
Before touching the equipment, hand-holding, circuit boards, or ASICs, a grounded electrostatic 
discharge(ESD) wrist strap should be worn to prevent the sensitive components from being 
damage by the electrostatic in human body.
