Installation of the RCD-ETU connecting cable
1. Remove the contact hazard protective cover.
2. Open the slide over the interface <X3 RCD>.
The slide is fitted as a protective guard (e.g. to protect the interface against soiling).
3. Insert one end of the connecting cable into the interface on the residual current device.
The interfaces and the connecting cable are labeled to ensure that the cable ends are
inserted in the right interfaces.
Note
Plug in or remove the RCD-ETU cable only when the residual current device is
deenergized.
