1 About this document

These instructions contain important information on the safe and

appropriate assembly, transport, commissioning, operation,

maintenance, and disassembly of the gripper and how to remedy

simple malfunctions yourself.

O Read this documentation completely, especially chapter “Basic

Safety Instructions”, before working with the gripper.

2 Basic Safety Instructions

The gripper has been manufactured according to the accepted

rules of technology. Even so, there is a risk of injury or damage if

the following general safety instructions and the specific warnings

given in this instruction manual are not observed.

O Read all these instructions completely before working with the

gripper.

O

Keep these instructions in a location where they are accessible

to all users at all times.

O Always include the assembly instructions when you pass the

gripper on to third parties.

Intended use

The gripper is exclusively intended for installation in a machine or

system or for combination with other components to form a

machine or system. The product may only be commissioned after

it has been installed in the machine/system for which it is

intended. The gripper and system may only be used under the

operating conditions and within the performance limits listed in

the technical data.

O Only use the gripper to grip loads within the scope of its

technical data.

Intended use includes having fully read and understood these

instructions, especially chapter “Basic Safety Instructions”.

Improper use

Do not use the gripper to crush connections or objects (e.g. pipe or

tubing fittings, sheet metal parts).

Personnel qualifications

Assembly, commissioning and operation, disassembly, service

(incl. maintenance and care) require basic mechanical, electrical,

and pneumatic knowledge, as well as knowledge of the applicable

technical terms. In order to ensure operational safety, these tasks

may only be carried out by qualified personnel or an instructed

person under the direction of qualified personnel.

Qualified personnel are those who can recognize possible hazards

and institute the appropriate safety measures, due to their

professional training, knowledge, and experience, as well as their

understanding of the relevant regulations pertaining to the work to

be done. Qualified personnel must observe the rules relevant to the

subject area.

pressure or voltage before assembling the product or when

connecting and disconnecting plugs. Protect the system

against being restarted.

W Lay cables and lines so that they cannot be damaged and no

one can trip over them.

W 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.

Assembling the gripper

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.

1. Tighten the gripper as shown in Fig. or Fig. .

– Use the provided centering rings E (2 pieces) for this.

2. Tighten the screws. See Fig. or Fig. for the tightening

torque.

Gripper fingers are assembled on the clamping jaws:

Notice: The gripper fingers are not supplied.

Connecting the gripper pneumatics

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.

O The gripper may only be assembled by qualified personnel

(see “Personnel qualifications”).

O Make sure that the gripper is securely fastened.
