Electrostatically Sensitive Devices
Important
Handling of modules containing devices sensitive to electrostatic discharge:
S
When handling electrostatically sensitive devices, make sure that operator,
workplace and packing material are properly grounded.
S
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.
S
Touch components only if
– you are permanently grounded by means of an antistatic chain,
– you are wearing ESD boots or ESD boots with grounding strips in
conjunction with ESD flooring.
S
Modules may be placed only on electrically conductive surfaces (table with
ESD top, conductive ESD foam plastic, ESD packing bags, ESD transport
containers).
S
Keep modules away from visual display units, monitors or TV sets
(minimum distance from screen > 10 cm).
S
Do not bring ESD–sensitive modules into contact with chargeable and
highly–insulating materials, such as plastic sheets, insulating table tops or
clothing made of synthetic materials.
S
Measurements on modules are allowed only if
– the measuring instrument is properly earthed (e.g. equipment grounding
conductor), or
– before measuring with a potential–free measuring instrument, the probe
is briefly discharged (e.g. touch the unpainted metal parts of the control
housing).
Setup and operation of the device/equipment/system in question must only be
performed using this documentation. Only qualified personnel should be al-
lowed to commission and operate the device/system. Qualified persons are
defined as persons who are authorized to commission, to ground, and to tag
circuits, equipment, and systems in accordance with established safety prac-
tices and standards.
Please note the following:
Warning
The equipment may only be used for single purpose applications explicitly
described in the catalog and in the technical description and it may only be
used along with third–party devices and components recommended by
Siemens. To ensure trouble–free and safe operation of the product, it must be
transported, stored and installed as intended and maintained and operated with
care.
