Installation and start-up
Actuators KNX R4 16 A and KNX R8 16 A
• Version: 28.05.2020 • Technical changes and errors excepted.
KNX R8 16 A:
The clamp groups [A1, A2, B1, B2] and [C1, C2, D1, D2] can be used with mixed voltag-
es, as there is increased insulation between them. Non-labelled clamps (X) may not be
used, to avoid influencing the insulation properties!

Insulation 6 kV (increased insulation)
