2Fundamental Safety Instructions
2.1Intended Use
The Ejector is designed to generate a vacuum for gripping and transporting objects when used in conjunc-
tion with suction cups.
The ejector is operated using discrete control signals.
Neutral gases are approved as evacuation media. Neutral gases include air, nitrogen and inert gases (e.g.
argon, xenon and neon).
The product is built in accordance with the latest standards of technology and is delivered in a safe oper-
ating condition; however, hazards may arise during use.
The product is intended for industrial use.
Intended use includes observing the technical data and the installation and operating instructions in this
manual.
2.2Non-Intended Use
Schmalz accepts no liability for damage resulting from non-intended use of the mini valve terminal.
In particular, the following types of use are considered non-intended use:
• Use in potentially explosive atmospheres
• Use in medical applications
• Lifting people or animals
• Evacuation of objects that are in danger of imploding
2.3Personnel Qualifications
Unqualified personnel cannot recognize dangers and are therefore exposed to higher risks!
1. Task only qualified personnel to perform the tasks described in these Operating instructions.
2. The product must be operated only by persons who have undergone appropriate training.
These Operating instructions are intended for fitters who are trained in handling the product and who
can operate and install it.
2.4Warnings in This Document
Warnings warn against hazards that may occur when handling the product. The signal word indicates the
level of danger.
Signal word Meaning
WARNING
Indicates a medium-risk hazard that could result in death or serious injury if
not avoided.
CAUTION
Indicates a low-risk hazard that could result in minor or moderate injury if
not avoided.
NOTE
Indicates a danger that leads to property damage.

8 / 52 EN-US · 30.30.01.01963 · 03 · 10/22
2.5Residual Risks
WARNING
Noise pollution due to the escape of compressed air
Hearing damage!
4Wear ear protectors.
4The ejector must only be operated with a silencer.
WARNING
Extraction of hazardous media, liquids or bulk material
Personal injury or damage to property!
4Do not extract harmful media such as dust, oil mists, vapors, aerosols etc.
4Do not extract aggressive gases or media such as acids, acid fumes, bases, biocides, dis-
infectants or detergents.
4Do not extract liquids or bulk materials, e.g. granulates.
WARNING
Uncontrolled movements of system components or falling objects caused by incor-
rect activation and switching of the Ejector while persons are in the plant (safety
door opened and actuator circuit switched off)
Serious injury
4Ensure that the components are enabled via the actuator voltage by installing a poten-
tial separation between the sensor and actuator voltage.
4Wear the required personal protective equipment (PPE) when working in the danger
zone.
CAUTION
Depending on the purity of the ambient air, the exhaust air can contain particles,
which escape from the exhaust air outlet at high speed.
Eye injuries!
4Do not look into the exhaust air flow.
4Wear eye protection.
CAUTION
Vacuum close to the eye
Severe eye injury!
4Wear eye protection.
4Do not look into vacuum openings such as suction lines and hoses.
