Any improper or inappropriate use might result in a state in which the operational safety
of the device cannot be guaranteed anymore. The manufacturer waives any liability for
resulting damages of persons and materials.
1.2 Notes on safety instructions and symbols
The devices have been designed to fulfil modern safety requirements. They have been
tested and delivered in a condition that ensures safe operation. However, improper or
non-intended use of the device may result in it becoming dangerous. Please always pay
attention to the safety instructions in this manual which are accompanied by the following
symbols:
WARNING

indicates an action or measure which, if performed incorrectly,
can potentially cause life-threatening injuries and lead to a high safety risk.
ATTENTION
CAUTION indicates an action or measure which, if performed incorrectly,
can cause minor to medium severe injuries.
NOTE

1.3 Safety instructions and precautionary measures
The manufacturer takes over no responsibility if the following safety instructions and pre-
cautionary measures are disregarded:
1. Changes to the device, which are implemented without prior written approval of
the manufacturer, lead to the immediate termination of product liability and warran-
ty.
2. Installation, operation, maintenance, repair and decommissioning of this device
must only be performed by specialists authorised by the manufacturer, operator or
owner of the device. The specialist needs to read and understand the entire instal-
lation and operation manual and is obliged to follow these instructions.
3. Control the supply voltage and information given on the type plate, before the de-
vice is installed.
4. Check all connections, settings and technical specifications of any available pe-
ripheral devices.
5. Open the housing or parts of the housing, which contain electrical or electronic
components, only if the electric energy is turned off.
6. Touch no electronic components (ESD sensitivity).
7. Expose the system concerning the mechanical load (pressure, temperature, IP
protection etc.) maximally to the specified classification.
8. For works concerning mechanical components of the system, the pressure in the
pipe system has to be released or the temperature of the medium needs to be
brought to values harmless for humans.
9. No information stated here or anywhere else releases planners, engineers, fitters
and operators from their personal careful and comprehensive evaluation of the re-
spective system configuration in terms of functionality and operational safety.
10.The local working and safety standards and statutes need to be met.
1.4 About the operation manual
The manufacturer reserves the right to change the technical details without prior notice.
The newest information and versions of this operation manual are available at your local
subsidiary or representation as well as on the website.
WARNING
Any liability is waived if the instructions and procedures
in this manual are
not followed!
NOTE
This installation instruction is intended for qualified personnel and contains
thus no basic working steps. Before putting AMBUS® Link or the system into
operation, the installation and operation manual needs to be read and un-
derstood completely.
