4.4 ESD protective equipment
i ESD (electrostatic discharge) that for example can
arise from rubbing against clothing can destroy
electronic devices or components when the ESD is
released by touching.
! Whenever work is performed on the supply module,
in particular near exposed printed circuit boards for
supply pumps, a protective device against ESD (see
the example in fig. 15) must be worn on the wrist
with a grounded connection to the mains voltage
system.
