Overview of the terminals in the heat pump control unit
Note
■ Route 230 V~ cables and LV cables
separately and bundle them tightly
together at the terminals. This ensures
that, in case of failure, for example
when detaching a wire, the wires can-
not drift into the adjacent voltage area.
■ Strip the insulation as close to the ter-
minals as possible.
■ If two components are connected to
the same terminal, press both wires
together into a single wire ferrule.
