• Use of the axial piston unit with assembled parts under water at a depth of more
than 10 meters without the necessary additional measures, e.g. pressure
equalization. Units with electrical components (e.g. sensors) generally cannot
come into contact with water. Axial piston units may only be used on a case-to-case
basis for this application.
• Size 60: The maximum permissible case pressure specified in data sheet 92703
must not be exceeded.
• Sizes 95 to 260: Use of the axial piston unit under a continuous pressure
differential between housing and ambient pressure greater than 2 bar, with
the ambient pressure always lower than the case pressure. Momentary (
t
< 0.1 s)
pressure peaks of up to 10 bar are allowed, but no more than 1000 pressure peaks
over the entire service life. Beyond this, the maximum permissible case pressure
specified in data sheet 92500 must not be exceeded.
• Size 520: Use of the axial piston unit under a continuous pressure differential
between housing and ambient pressure greater than 2 bar (at nominal speed), with
the ambient pressure always lower than the case pressure. Momentary (
t
< 0.1 s)
pressure peaks of up to 6 bar are allowed. Beyond this, the maximum permissible
case pressure specified in data sheet 92050 must not be exceeded.
• Use of the axial piston unit in potentially explosive areas unless
the component or machine/system has been certified as compliant with
the ATEX Directive 2014/34/EU
• Use of the axial piston unit in a corrosive atmosphere
• Use of the axial piston unit in aircraft or spacecraft
2.4 Personnel qualifications
The activities described in this documentation require a basic understanding
of mechanics, electricity and hydraulics, as well as familiarity with associated
technical terms. For transporting and handling the product, knowledge regarding
the use of lifting devices and lifting accessories is required. In order to ensure safe
use, these activities should only be performed by skilled personnel or an instructed
person under the direction and supervision of skilled personnel.
Skilled personnel refers to persons who possess the professional training,
knowledge and experience, as well as the understanding of the regulations relevant
to the work to be done that are necessary to recognize possible dangers and take
the appropriate safety measures. Skilled personnel must follow the rules relevant
to their field and have the necessary hydraulic expert knowledge.
Hydraulic expert knowledge includes:
• Being able to read and fully understand hydraulic circuit diagrams,
• in particular, fully understanding the relationships with regard to safety devices
• comprising of knowledge regarding the function and layout
of hydraulic components.
