Note on electrostatic shielding
1. Electrostatically shielded MOS workstations
Components sensitive to electrostatic discharge
must be handled at workstation with electrostatic
shielding. An electrostatically shielded MOS work-
station is fi tted with discharge resistor which earth
all conductive materials, including the technician
working there. Dielectrics are discharged by air
ionisation. The use of soldering irons and meas-
uring equipment at shielded workstation is only
possible in conjunction with isolating transformer
in each of the devices used. Measuring equip-
ment chassis are also earthed with discharge re-
sistors.
2. Shielded packaging using conductive
materials
To protect against electrostatic charges, electri-
cally conductive plastics are used for packaging
and transport purposes. Conductive plastics are
available in the form of transparent protective
bags, foam plastic, fi lm sheeting or containers.
Sensitive components requiring the use of pro-
tective packaging must only be packed and un-
packed at shielded workstations.
Safety warnings/regulations
1. The repair, modifi cation and testing of mains-op-
erated electronic devices and their accessories
must only be performed by qualifi ed persons.
2. It is necessary to follow the regulations and safety
warnings to VDE 0701, part 200, as well as the
regulations and safety warnings applicable in the
country concerned.
3. VDE 0701, Part 2, contains regulations on the re-
pair, modifi cation and testing of mains-operated
electronic devices and their accessories.
4. Before delivery, the device and the connecting
leads (including any protective earth conductor
fi tted) must undergo visual inspection, and the
insulation resistance and the equivalent leak-
age current must be measured according to VDE
0701, part 200. The low-resistance continuity of
the protective earth conductor must be verifi ed by
measurement to VDE regulation 0701, part 1.
5. The regulations of the country concerned must
also be observed.
6. Only genuine parts must be used for replacing
components marked with the symbol
