1 SAFETY INSTRUCTIONS
Important symbols

This symbol identifies important information and instructions.
Caution!
This symbol identifies a potentially dangerous situation.
If it is not avoided, slight or minor injuries may result.
Danger!
This symbol identifies an immediate hazard.
If it is not avoided, death or serious injuries may result.
General safety information
These operating instructions contain important information on using the ejector. Please
read the operating instructions thoroughly and keep them for later reference.
Never look into any open or closed vacuum vents (e.g. vacuum connec-
tions or suction pads).
Serious injuries could occur as a result. Eyes can be sucked in.
Compressed air can cause closed containers to explode. A vacuum can cause closed
containers to implode.
The ejector may only be operated with a silencer. Never look into the exhaust air jet of
the silencer.
The ejector emits noise. We recommend wearing ear protection.
This device is not intended for use with hazardous dust, oil mist, vapours or aerosols,
etc. If drawn in, these materials will enter the exhaust air and may result in poisoning.

Use only the connections, attachment holes and attachment materials that have been
provided.
Carry out mounting and removal only when the device is in a disconnected, depressur-
ised state.
Do not sit or stand in the area in which the picked-up payload is transported.
Do not sit or stand in the danger area while the machine or system is in automatic mode.
Components may be installed by trained specialist personnel only.
Specialist personnel must be familiar with the most current safety rules and require-
ments. These apply to the use of such components as solenoid valves and pressure
switches and to control units for devices, machines and systems, for example.
Specialist personnel must also be familiar with the system’s control concept. In particu-
lar, they must be familiar with the system’s redundant control components and feedback
signals.
Intended use
The ejector is designed for generating a vacuum for gripping and transporting objects when
used with suction pads. Neutral gases in accordance with EN 983 are approved as media to
be evacuated. Neutral gases include air, nitrogen, and inert gases (e.g. argon, helium and
neon). Aggressive gases or media such as acids, acid fumes, bases, biocides, disinfectants
or detergents are not permitted.
The ejector is not suitable to be used for the transportation or through-suction of
liquids or bulk materials such as granulates.
Personal injury or damage to the ejector may otherwise occur.
The ejector must not be used to fill pressurised containers or to drive cylinders,
valves or other pressure-operated function elements.
Personal injury or damage to the ejector may otherwise occur.
