1.1 Introduction
This system has been developed in line with the present state-of-the-art and
fulfils the current national and international safety requirements. It is provided
with a high degree of operational safety resulting from many years of develop-
ment experience and continuous stringent quality checks in our company.
In normal operation, this system is safe.
There are, however, some potential sources of danger that cannot be com-
pletely eliminated.
This Hardware Description therefore contains basic safety instructions that
must be observed during system configuration and operation. This Hardware
Description must be read before the system is used and the current version of
the document must always be kept close to the equipment.
All safety instructions have a uniform appearance. This appearance is de-
scribed in detail in CHAPTER 1.3.
1.2 General safety requirements
In order to keep the technically unavoidable residual risk to a minimum, it is
imperative to observe the following rules:
–Transport, storage and operation of the unit/system must be under
the permissible conditions only.
– Installation, configuration and disassembly must be carried out only
by expert personnel and with reference to the respective documenta-
tion.
– The system must be operated by expert and authorised users only.
– The system must not be operated unless it is in perfect working or-
der.
–Any conversions or changes to the system or parts of the system
(including the software) must be carried out by qualified personnel
from our company or by expert personnel authorised by our com-
pany.
All changes carried out by other persons lead to a complete exemption
from liability.
– The removal or disabling of safety facilities, the clearing of faults and
errors, and the maintenance of the equipment must be carried out by
specially qualified personnel only.
– Non-system software is used at one’s own risk. The use/installation
of non-system software can adversely affect the normal functioning
of the system software.
– Only use tested and virus-free data carriers!

Safety
1.3 Appearance of the safety instructions
All safety instructions include a signal word that classifies the danger and a
text block that contains descriptions of the type and cause of the danger, the
consequences of ignoring the safety instruction and the measures that can be
taken to minimise the danger. In some safety instructions, a warning symbol
is placed underneath the signal word (see also CHAPTER 1.3.2):
1.3.1 Classification of safety instructions
There are five classes of safety instructions: “Danger”, “Warning”, “Caution”,
“Notice” and “Important”. The classification is shown in the following table.
The signal word “Note” is also used in this Hardware Description. Text pas-
sages marked in this way do not describe a danger, but rather contain remind-
ers, tips and general information to ensure optimum operation of the system.
1.3.2 Symbols
The following warning symbols are used:
