void the warranty.
NOTICE
Voltage can destroy electrostatic-sensitive modules
The device contains modules that are sensitive to electrostatic discharge. ESD devices can
be destroyed by voltages well below the threshold of human perception. Such voltages
occur if you touch a component or electrical connectors of a module without first
discharging the static from your body. The damage caused by overvoltage on a module
cannot normally be detected immediately and only becomes apparent after a longer period
of operation.
Measures for protecting against discharge of static electricity:
• Before working with modules, make sure that you discharge static from your body, for
• The devices and tools used must also be free of static charges.
• Interrupt the power supply.
• Pick up the modules only on their edges and do not touch any pins or printed
