ESD directives

NOTICE
Electrostatic sensitive devices can be destroyed by voltages which are far below the human perception limit. These
voltages already occur if you touch a component or the electric connections of a module without being electrostatically
discharged. The damaged caused on a module by an overvoltage is not usually recognized immediately, but only becomes
evident after a longer period of operation.
Fundamental measures to protect against static discharge
● Provide good grounding:
When handling electrostatic sensitive devices, provide good grounding for persons, workstation and packaging. In this
manner you avoid static discharge.
● Avoid direct touching:
Only touch electrostatic sensitive devices when this is absolutely unavoidable (e.g. during maintenance). Hold the
modules so that you touch neither pins nor printed conductors. In this manner, the discharge energy cannot reach or
damage sensitive devices.
If you have to carry out measurements on a module, discharge yourself before carrying out any actions. To do this, touch
grounded metal objects. Only use grounded measuring instruments.
