7.1 Installation
WARNING!
Risk of injury due to unexpected movement of components.
• Bring moving parts of the connected mechanical system into a secure position (e.g.move into the lower end position).
Mount motor
1. Clean motor shaft. The motor shaft must be dry and free of grease.
2. Fasten the motor to the driven mechanical system è accompanying documents.
7.2 Mounting accessories
– Use Festo accessories èwww.festo.com/catalogue.
8 Electrical installation
WARNING!
Risk of injury due to electric shock.
• Switch off power supply prior to assembly and installation work; ensure that
it is off and secure it against being switched back on.
Cancelling the enable signal is not sufficient.
1. Connect cable to the servo drive èObserve documentation for cable and
servo drive.
2. Connect cable to the motor.
– Conductor cross-section must be adequately dimensioned.
– Use screened cables.

WARNING!
Risk of injury due to unexpected movement of components.
• When releasing the holding brake, secure the driven mechanical system to
prevent unintended movement.
• Deenergise the motor before releasing the holding brake manually.
• Before setting the enable signal, protect the traversing range of the driven
mechanical system from access.
– Commission the motor together with the servo drive èDocumentation for
servo drive.
10 Operation
WARNING!
Danger of burns from hot housing surfaces.
Metallic housing parts can reach high temperatures during operation.
Contact with metal housing parts can cause burn injuries.
• Do not touch metallic housing parts.
• After the power supply is switched off, let the device cool down to room temperature.
