1.2 ESD notices
CAUTION
The modules contain electrostatically sensitive devices. Discharge yourself of electrostatic
energy before touching the components. The easiest way to do this is to touch a
conductive, grounded object immediately beforehand (for example, bare metal parts of
control cabinet or the protective ground contact of a socket outlet).
NOTICE
Handling ESD-modules:
When handling electrostatically sensitive devices, make sure that operator, workplace
and packing material are properly grounded.
Generally, electronic modules must not be touched unless work has to be carried out on
them. When handling PCBs make absolutely sure that you do not touch component pins
or printed conductors.
Touch components only if:
– You are permanently grounded via an ESD armband
– You are wearing ESD shoes or ESD shoe-grounding-strips, if ESD flooring is
available
Modules may only be placed on electrically conductive surfaces (table with ESD top,
conductive ESD foam plastic, ESD packaging bags, ESD transport containers).
Keep modules away from visual display units, monitors or TV sets (minimum distance
from screen 10 cm).
Do not bring ESD-sensitive modules into contact with chargeable and highly-insulating
materials, such as plastic, insulating table tops or clothing made of synthetic materials.
Measurements on modules are allowed only if:
– The measuring instrument is properly earthed (e.g., protective conductor) or
– Before measuring with a floating measuring instrument, the probe is briefly
discharged (e.g., touch the bare metal parts of the control housing).
