Note
If unused plug connectors are touched, there is a danger that damage may occur to the
ERMO or to other parts of the system as a result of electrostatic discharge (ESD).
To avoid such discharges: Use protective caps on unused ports.
Note
To ensure compliance with EMC safety:
The maximum length of the individual cables should not exceed 30 m.
1. Switch off power to the controller and secure it from being restarted accidentally.
Cancelling the enable signal on the controller is not sufficient.
2. Wire the motor to the controller in accordance with the following tables.
The pre-assembled cables from Festo offer sufficiently large cable cross-sections as well as screen
ing of the motor/encoder cable with earth contact on both sides (è 10 Accessories).
