CAUTION Indicates a hazardous situation which, if not avoided, could result in minor or moderate injuries.

NOTICE Indicates that damage may be inflicted on the product or the environment.

The following must be observed:
General information

• Observe the valid local regulations in the country of use to protect the environment and avoid workplace accidents.
• Only use AVENTICS grippers that are in perfect working order.
• Examine the product for obvious defects, such as cracks in the housing or missing screws, caps, or seals.
• Do not modify or convert the grippers.
• Only use the device within the performance range provided in the technical data.
• Do not place any improper mechanical loads on the product under any circumstances. Never use the product as a handle or step. Do not place loose objects on it.

On installation

• Make sure the relevant system component is not under pressure or voltage before assembling the product or when connecting and disconnecting plugs. Protect the system against being restarted.
• Lay cables and lines so that they cannot be damaged and no one can trip over them.
• Before commissioning, make sure that all the seals and plugs for the compressed air connections have been installed correctly and without any damage to prevent fluids and foreign bodies from penetrating the product.

During operation

• Only authorized personnel are allowed to operate the setting mechanisms of the components or parts, under the proviso that the pneumatic system is used as intended.
• Only allow persons who are authorized by the system owner to access the system’s direct operating area. This is also valid when the system is standing still.

During service and repairs
Make sure that no line connections, ports, and components are disconnected as long as pressure and voltage are applied in the system. Protect the system against being restarted.

Assembly

Assembling the gripper

CAUTION
Risk of injury or damage due to improper assembly!
An incorrectly mounted gripper may result in uncontrolled movements that could injure personnel or damage other system parts. Gripper assembly requires basic mechanical, pneumatic, and electrical knowledge.

• The gripper may only be assembled by qualified personnel (see “Personnel qualifications”).
• Make sure that the gripper is securely fastened.

There are various options for gripper assembly:
There are mounting threads with a center hole on the mounting surface that can be used for assembly.

• **3** On the base
  • 2 mounting threads with center hole C
  • 2 mounting threads D
  • 4 through-holes H
• **4** On the side
  • Side with 2 through-holes

1. Tighten the gripper as shown in Fig. **3** or Fig. **4**
   • Use the provided centering rings E (2 pieces) for this.

2. Tighten the screws. See Fig. **3** or **4** Fig. for the tightening  torque.

Gripper fingers are assembled on the clamping jaws:
Notice: The gripper fingers are not supplied.

• **5** Gripper fingers can be assembled from the top via 4 through-holes on the clamping jaws.
  • 2 mounting threads with center hole per clamping jaw

Connecting the gripper pneumatics

CAUTION
Danger of injury if assembled under pressure!
Injuries and damage to the device or system components may occur if the pressure is not switched off before beginning assembly.

• Make sure that the relevant system part is not under pressure before you assemble the product.

There are two options for connecting the gripper pneumatics:

• **6** Compressed air connection for fittings
  • Connection A = open gripper
  • Connection B = close gripper
  • Connection S = sealing air
• **7** Compressed air connection for flange mounting (F = flange/G = gripper)
  • Connection a = open gripper
  • Connection b = close gripper
    Variant I: flange mounting on the side
    Variant II: flange mounting on the base

► Connect the pneumatic connections to the gripper as shown in Fig. **6** and Fig. **7**
• Use the provided O-rings K (2 pieces) for this.

Commissioning

CAUTION
Risk of injury or damage!
If the gripper has not been assembled correctly, personnel may be injured and the product or system damaged when the gripper is commissioned.

• Make sure that the gripper has been assembled by qualified personnel before commissioning it.
• The gripper may only be commissioned by qualified personnel (see “Personnel qualifications”).

Proceed as follows to commission the gripper:

1. Before commissioning, make sure that all the connections on the gripper are properly connected and all of the tubing are firmly fitted.
2. Switch on the operating pressure.

First-time commissioning
Perform a function test if commissioning the system for the first time:

• Switch the compressed air on at compressed air connection A/a. The gripper opens.
• Switch the compressed air on at compressed air connection B/b. The gripper closes.

Operation

WARNING
Danger of crushing and shearing between the clamping jaws and gripper fingers!
Persons or extremities may be crushed during operation.
Extremities, such as fingers, may be severed by this.

• Make sure that no persons are in the hazardous area during operation.
• Do not reach into the open mechanics or between the clamping jaws.

CAUTION
Danger of injury due to falling or ejected gripper objects!
If the power supply fails, the gripper objects may fall or be ejected (depending on the application).

• Make sure that no persons are in the hazardous area during operation.
• Use protective devices to catch any ejected parts (e.g. a protective grid).
• Install pressure maintenance valves in your system.
• Install mechanical devices to retain the gripping force.

Gripping safety when the emergency OFF function is actuated!
Grippers with a mechanical gripping safety can still move independently in the stipulated direction after an emergency OFF.

• Make sure that no persons are in the hazardous area of the gripper.
