Installation, Maintenance, and Troubleshooting of Siemens C7-623/624

Electrostatic Discharge (ESD) and Safety Regulations

C7 contains a large number of electronic components that are extremely sensitive to static electricity inside. When the human body walks or comes into contact with plastic products, it may generate thousands or even tens of thousands of volts of static electricity voltage. When this voltage is discharged, the human ear may not even be able to detect it, but it is enough to break through integrated circuits.

Before touching C7 or any module, it is necessary to release human static electricity by touching grounded metal parts (such as cabinet shells).

A grounded ESD wristband must be worn.

The removed circuit board or module must be placed in the conductive ESD foam or ESD shielding bag. It is strictly prohibited to place it on the plastic bag, carton or insulated desktop.
