Conversions and modifications
HBM's express consent is required for modifications affecting the transducers's
design and safety. HBM does not take responsibility for damage resulting from
unauthorized modifications.
Qualified personnel
The transducer may be used by qualified personnel only; the specifications and
the special safety regulations need to be followed in all cases. It is also essen­
tial to comply with the appropriate legal and safety regulations for the applica­
tion concerned during use. The same applies to the use of accessories.
Qualified personnel means: personnel familiar with the installation, fitting, start-
up and operation of the product, and trained according to their job.
Prevention of accidents
According to prevailing accident prevention regulations, it is essential that after
mounting the transducers the user fits a cover or enclosure as follows:
S The cover or enclosure must not be able rotate.
S The cover or enclosure shall protect against crushing or cutting and provide
protection against parts that might come loose.
S The covers and enclosures shall be installed at a safe distance from moving
parts or shall prevent anyone putting their hand inside.
S The covers and enclosures shall even be fitted if the moving parts are
installed in areas to which persons do not usually have access.
The above regulations may only be diverged from, if machine parts are already
sufficiently protected owing to the design of the machine or because other pre­
cautions have been taken.
