4.6.8 Ferrite core for data cable
A plastic bag with a shield clamp and a ferrite core is supplied with each universal supply module.
The ferrite core is only needed when using the USB-SPP interface.
It is used for shielding and avoiding external interferences on the data line.
The ferrite core must be mounted as follows:
- Strip the insulation of data cable
- Push the ferrite core over the data cable.
- Snap the shield clamp onto the DIN rail in the universal supply module.
- Press the ferrite core into the shield terminal.
- Place the data cable with bare shield in the shield terminal.
- Connect the data line to the terminal.
