NOTICE
Handling ESD modules:
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).
● 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 PC boards make absolutely sure that you do not touch component
pins or printed conductors.
● Touch components only if:
– you are constantly grounded via an ESD arm band,
– ESD shoes or ESD shoe grounding strips if there is an ESD floor.
● Boards/modules must only be placed on conductive surfaces (table with ESD surface,
conductive ESD foam, ESD packaging, ESD transport container).
● 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).
