Overview of electrical connections
Note
Route 230 V~ cables and LV cables separately and
■
bundle them tightly together at the terminals. This
ensures that, in the event of a fault, e.g. when
detaching a wire, the wires cannot drift into the adja-
cent voltage area.
Strip the insulation as close to the terminals as pos-
■
sible.
■
If 2 components are connected to the same terminal,
press both cores together in a single wire ferrule.
