Connecting Signal Source to Digital Input

Qualified person

It is possible to connect a digital signal source (e.g. ripple control receiver or remote terminal unit) to the digital input of the product. This must be connected if it is prescribed by the grid operator.

Additionally required material (not included in the scope of delivery):

  • Connection cable

  • Bootlace ferrules (only for multi-core stranded wire, usable length of the ferrule at least 12 mm)

Requirements for connection cable:

  • Cable with shielding: Yes

  • External diameter: 5.3 mm to 7 mm

  • UV-resistant for outdoor use.

Requirements:

  • The signal source must be technically suitable for connection to the digital inputs ( > Technical Data).

  • The connected digital signal source has a safe separation to the grid potential.
