2 Fundamental Safety Instructions
2.1 Intended Use
The product is built in accordance with the latest standards of technology and is delivered in a safe operating con-
dition; however, hazards may arise during use.
The RECB is designed to generate pneumatic vacuum for gripping and transporting objects when used in conjunc-
tion with suction cups. The RECB was developed especially for use on collaborative robot systems. Only specified
compact ejectors (SCPSi) from Schmalz may be inserted into the housing of the RECB since the housing has been
specially adapted to them.
The goods to be lifted should ideally be dry, airtight, rigid and have a smooth surface. Porous or unstable objects
must be tested for suitability before they are handled with vacuum. Contamination of the products can impair
their functionality.
Neutral gases in accordance with EN983 are approved as evacuation media. Neutral gases include air, nitrogen and
inert gases (e.g. argon, xenon and neon).
The product is intended for industrial use.
Intended use includes observing the technical data and the installation and operating instructions in this manual.
The device may only be used with robot systems that comply with the provisions of DIN ISO/TS 15066, DIN EN ISO
10218-1 and DIN EN ISO 10218-2.
Operation as part of a collaborative system is only permitted when the entire system meets the corresponding legal
requirements for collaborative robot systems. The system integrator is responsible for ensuring that these require-
ments are complied with.
2.2 Non-Intended Use
Schmalz does not accept any liability for any direct or indirect losses or damages that result from using the product.
This applies, in particular, to any use of the product that is not in accordance with the intended purpose and to any
use that is not described or mentioned in this documentation.
Non-intended use includes the following:
• Use in potentially explosive atmospheres
• Transport and through-suction of potentially explosive materials
• Use for medical applications
• Use as a clamping device for workpiece processing
• Suction of body parts
• Use with workpieces not suited for suctioning
• Exceeding the lift capacity
• Storing loads while picked up

2.3 Safety
The RECB emits noise due to its use of compressed air.
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, disinfectants
or detergents.
4Do not extract liquids or bulk materials, e.g. granulates.
WARNING
Uncontrolled movements of system components or falling of objects caused by incorrect ac-
tivation and switching of the Ejector while persons are in the plant (safety door opened
and actuator circuit switched off)
Serious injury
4Ensure that the valves and ejectors are enabled via the actuator voltage by installing a potential
separation between the sensor and actuator voltage.
4Wear the required personal protective equipment (PPE) when working in the danger zone.
CAUTION
Compressed air or vacuum in direct contact with the eye
Severe eye injury
4Wear eye protection
4Do not look into compressed air openings
4Do not look into the silencer air stream
4Do not look into vacuum openings, e.g. suction cups
CAUTION
Depending on the purity of the ambient air, the exhaust air can contain particles, which es-
cape from the exhaust air outlet at high speed.
Eye injuries
4Do not look into the exhaust air flow
4Wear eye protection
2.4 Personal Protective Equipment
To avoid injury, always use appropriate protective equipment that is suitable for the situation. The protective
equipment must meet the following standards:
• Protective work shoes in safety class S1 or higher
• Sturdy work gloves in safety category 2231 or higher
EN-US · 30.30.01.02586 · 00 · 11/20 5 / 18
• Ear protection class L or higher
• Eye protection class F
• Hair net
• Closely fitting clothing
2.5 Personnel Qualifications

Personal injury or damage to property
4Prior to installation and before maintenance work, the vacuum generator must be disconnected
from the power supply and secured against unauthorized restart!
8 / 18 EN-US · 30.30.01.02586 · 00 · 11/20
For safe installation, the following instructions must be observed:
1. Use only the connections, mounting holes and attachment materials that have been provided.
2. Firmly connect and secure pneumatic and electrical line connections to the vacuum generator.
7.2 Installing the RECB
WARNING
Falling objects due to improper mounting
Serious injury!
4Using a torque wrench, tighten the screws of the flange connection on the bottom side of the
housing as well as the set screws for the flange connection on the top side of the housing to the
specified tightening torques.
4Wear protective work shoes.
CAUTION
Potential contact with sharp-edged components during connection work
Hand injuries!
4Wear suitable work gloves.
The RECB must not be exposed to strong vibrations.
Always apply a low-strength threadlocker to the fastening screws (e.g. Loctite 221) after opening and
closing the housing.
7.2.1 Connecting the RECB to the Compressed Air and Electrical Connection
The RECB must be opened to connect it to the compressed air supply and to establish the electrical connection.
üAllen wrench sizes SW 3 and 6 are available for use.
üLow-strength threadlocker (e.g. Loctite 221) is available.
üProvide a connection cable with an angle M12 5-pole socket (not included in delivery).
1. Unscrew and remove the three M4x16 mm screws
on the bottom.
2. Rotate the RECB and remove the top housing shell.
EN-US · 30.30.01.02586 · 00 · 11/20 9 / 18
3. To lift the compact ejector, unscrew and remove
the M4 screw.
4. Pull the pre-assembled compressed air hose
through the housing so that the compact ejector
can be easily lifted. This facilitates the installation
of the connection cable and compressed air hose.
5. Attach the connection cable to the compact ejector
(maximum tightening torque = hand-tight).
6. Check the fit of the hoses in the plug connections
(vacuum and compressed air) and ensure complete
insertion.
