Overview of electrical connections
Note
■
Route 230 V~ cables and LV leads separately and
bundle them tightly together at the terminals. This
ensures that, in the event of a fault, e.g. if a wire
becomes detached, the wires cannot drift into the
adjacent voltage area.
■
Strip the cables of a small amount of insulation close
to the terminals.
■
If 2 components are connected to the same terminal,
press both cores together in a
single
wire ferrule.
