NOTICE
Electrostatic-sensitive devices
The
device contains electrostatic-sensitive devices (ESD). ESD can be destroyed by voltages
far too low to be detected by humans. These voltages can occur if you simply touch a
component part or the electrical connections of a module without being electrostatically
discharged. The damage to a module caused by overvoltage cannot normally be detected
immediately; it only becomes apparent after a longer period of operating time has elapsed.
Protective measures against the discharge of static electricity:
Make sure that no power is applied.
Before working with modules, make sure that you discharge static from your body, for
example by touching a grounded object.
Devices and tools used must be free of static charge.
Hold modules only by their edges.
Do not touch connector pins or conductor tracks on a module with the ESD notice.

Defining the maintenance interval
WARNING
No maintenance interval has been defined
Device failure, device damage, and risk of injury.
Define
