• 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

03.00 | PWG-S | Assembly and operating manual | en | 389361
Incorrect lifting of loads
Falling loads may cause serious injuries and even death.
• Stand clear of suspended loads and do not step into their
swiveling range.
• Never move loads without supervision.
• Do not leave suspended loads unattended.
2.13.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
• Take appropriate protective measures to secure the danger
zone.
• Never step into the danger zone during operation.
2.13.3 Protection against dangerous movements
Basic safety notes
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
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, 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.

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.
Assembly
• 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 [}13].
• 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.

The inductive proximity switches used are equipped with reverse
polarity protection and are short-circuit-proof.
Make sure that you handle the proximity switches properly:
• Do not pull on the cable.
• Do not allow the sensor to dangle from the cable.
• Do not overtighten the mounting screw or mounting clip
• Please adhere to a permitted bend radius of the cable (☞
cataolg).
• Avoid contact of the proximity switches with hard objects and
with chemicals, in particular nitric acid, chromic acid and
sulphuric acid.
03.00 | PWG-S | Assembly and operating manual | en | 389361
17
Assembly
The inductive proximity switches are electronic components,
which can react sensitively to high-frequency interference or
electromagnetic fields.
• Check to make sure that the cable is fastened and installed
correctly. Provide for sufficient clearance to sources of highfrequency interference and their supply cables.
• Parallel switching of several sensor outputs of the same type
(npn, pnp) is permissible, but does not increase the permissible
load current.
• Note that the leakage current of the individual sensors (approx.
2 mA) is cumulative.
• If you require further information on sensor operation, contact
your SCHUNK contact person or download information from our
homepage.
• Technical data for the sensors can be found in the data sheets
(included in the scope of delivery).
