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
 Generally, electronic modules must not be touched unless work has to be carried out on
 Touch components only if:
 Modules may only be placed on electrically conductive surfaces (table with ESD top,
 Keep modules away from visual display units, monitors or TV sets (minimum distance
 Do not bring ESD-sensitive modules into contact with chargeable and highly-insulating
 Measurements on modules are allowed only if:
