General Regulations
Right to make Changes
Trebing & Himstedt Prozeßautomation GmbH & Co. KG reserves the right to make changes to this manual
and to the specifications of the hardware and software at any time and without warning or prior notice.
Liability and Guarantee
Trebing & Himstedt Prozeßautomation GmbH & Co. KG assumes no warranty that the hardware and software
will perform correctly in all conceivable situations. With technical aids and methods currently available , it is
not possible to develop software which is completely free of errors in all conceivable applications. Accordingly,
Trebing & Himstedt Prozeßautomation GmbH & Co. KG does not accept any liability for damage, both direct
and indirect, arising from the use of the hardware and software and/or the information contained in this
manual.
ESD Guidelines
The hardware contains electronic components which are sensitive to electrostatic discharge. Before touching
the printed circuit board, you should first discharge electrostatic voltages from your body by using a grounded
anti-static wristband or anti-static shoes and a grounded anti-static carpet. A simple precaution is to touch a
grounded, electrically conducting surface such as a heating radiator, water pipe or unpainted surface of a
grounded control cabinet. Damage due to electrostatic discharge may not be immediately apparent, and can
lead to the following types of fault at a later stage:
– premature failure of components and modules,
– fluctuation of typical performance characteristics,
– intermittent faults,
– temperature-dependent faults.
An electrostatic discharge can only be perceived by humans in case of high-level voltage. However, lower
electrostatic voltages which are below the limits of perception can still damage or destroy electronic
components.

Product Observation Liability
Within the framework of our product observation liability, we do our best to warn third parties of dangers we
have identified which can result from the interaction of hardware and software and the usage of our products.
This is only possible if we receive sufficient information from our customers on the planned application(s) and
the existing hardware and software components. As a result of the complex interactions, it is no longer
possible for us to accurately identify all dangers and to check the effect on the overall system and in particular
on our hardware and software if the conditions of application have changed and/or hardware or software has
been exchanged. This manual does not describe all technical characteristics of the hardware and software
and the available versions. Please contact Trebing & Himstedt Prozeßautomation GmbH & Co. KG for further
information.
Warranty
Our products are subject to warranty in accordance with our general business and delivery terms.
