safety and cause serious injuries as well as considerable material
and environmental harm.
• Follow local regulations on dispatching product components for
recycling or proper disposal.
2.13 Fundamental dangers
General
• Observe safety distances.
• Never deactivate safety devices.
• Before commissioning the product, take appropriate protective
measures to secure the danger zone.
• Disconnect power sources before installation, modification,
maintenance, or calibration. Ensure that no residual energy
remains in the system.
• If the energy supply is connected, do not move any parts by
hand.
• Do not reach into the open mechanism or movement area of
the product during operation.
2.13.1 Protection during handling and assembly

Basic safety notes
03.00 | GSM-W | Assembly and operating manual | en | 389108
13
2.13.3 Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its ac-
tion being dependent on the control unit and the current oper-
ating condition of the drive. Perform maintenance work, modi-
fications, and attachments outside the danger zone defined by
the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective
fence must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Before starting up the machine or
automated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.
2.13.4 Protection against electric shock
Possible electrostatic energy
Components or assembly groups may become electrostatically
charged. When the electrostatic charge is touched, the discharge
may trigger a shock reaction leading to injuries.
• The operator must ensure that all components and assembly
groups are included in the local potential equalisation in
accordance with the applicable regulations.
• While paying attention to the actual conditions of the working
environment, the potential equalisation must be implemented
by a specialist electrician according to the applicable
regulations.
• The effectiveness of the potential equalisation must be verified
by executing regular safety measurements.

•Stand clear of suspended loads and do not step within their
swiveling range.
•Never move loads without supervision.
•Do not leave suspended loads unattended.
•Wear suitable protective equipment.
WARNING
Risk of injury from objects falling and being ejected!
Falling and ejected objects during operation can lead to serious
injury or death.
•Take appropriate protective measures to secure the danger
zone.
WARNING
Risk of injury due to unexpected movements!
If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
•Before starting any work on the product: Switch off the power
supply and secure against restarting.
•Make sure, that no residual energy remains in the system.
WARNING
Risk of injury from crushing and impacts!
Serious injury could occur during the base jaw procedure and
when breaking or loosening the gripper fingers.
•Wear suitable protective equipment.
•Do not reach into the open mechanism or the movement area
of the product.

Basic safety notes
03.00 | GSM-W | Assembly and operating manual | en | 389108
15
WARNING
Risk of injury due to spring forces!
Parts are under spring tension on products which clamp using
spring force or which have gripping force maintenance. While dis-
assembling components can move unexpectedly and cause seri-
ous injuries.
•Disassemble the product cautiously.
•Make sure that no residual energy remains in the system.
WARNING
Risk of injury from objects falling during energy supply failure
Products with a mechanical gripping force maintenance can,
during energy supply failure, still move independently in the
direction specified by the mechanical gripping force
maintenance.
•Secure the end positions of the product with SCHUNK SDV-P
pressure maintenance valves.
WARNING
Danger of injury due to uncontrolled movements!
Due to incorrect control and incorrect operation, loss of work-
pieces and uncontrolled movement of the product may occur and
can cause serious injuries.
•Take checks in the user's program.
•The danger zone must be secured by suitable measures.
WARNING
Risk of injury from rotating components!
In the case of swivel units or rotary tables with a rotary drive,
serious injuries can be caused by rotating components.
•Take appropriate protective measures to secure the danger
zone.
WARNING
Risk of injury by parts becoming detached and destruction of
the rotary actuator if the shock absorbers are defective.
Avoidance measures: Regular visual inspections of individual
components for wear and damage.

WARNING
Risk of injury due to unexpected movements!
If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
•Before starting any work on the product: Switch off the power
supply and secure against restarting.
•Make sure, that no residual energy remains in the system.
NOTICE
Damage to the gripper is possible!
If the maximum permissible finger weight or the permissible
mass moment of inertia of the fingers is exceeded, the gripper
can be damaged.
•A jaw movement always has to be without jerks and bounce.
•You must therefore implement sufficient reduction and/or
damping.
•Observe the diagrams and information in the catalog data
sheet.
NOTE
• Observe the requirements for the compressed air supply,
Technical data [}16].
• In case of compressed air loss (cutting off the energy line), the
components lose their dynamic effects and do not remain in a
secure position. However, the use of a SDV-P pressure
maintenance valve is recommended in this case in order to
maintain the dynamic effect for some time. Product variants are
also offered with mechanical gripping force via springs, which also
ensure a minimum clamping force in the event of a pressure drop.
