system, for example in a machine.
Chapter "2.1 Intended operation", page 5
The following must be completed before the valve is operated:
• Qualified project planning
• Correct start-up and configuration of the valve
WARNING
Only properly qualified and authorized users may work
with and on the valves.

WARNING
Prior to start-up, the valves must be checked for correct
mechanical design. Wrong mechanical design of the
valves will result in danger due to:
• Uncontrolled sequences of motions
• Destruction
• Malfunction
CAUTION
To provide protection against injuries or other damaging influ-
ences on health, suitable protective measures must be taken if
necessary prior to and when carrying out any work on the
valves or the machine, such as e.g., mounting or removing,
electrical or hydraulic connection, troubleshooting or servicing,
and when handling the valves, accessories, tools or hydraulic
fluids.
Chapter "2.6 Occupational safety and health", page 9
CAUTION
Dirt or moisture can get into the valve through open connec-
tors, i.e., if no mating connector is attached, which may result
in damage to the valve.
Open connectors must be covered and sealed.
