Options for use of the labeling fields “Appl.” and “Loc.”:
Handwritten identification of the location and the activated application group.
All terminals are detachable plug-in screw-terminals. To avoid incorrect wiring,
terminals which can be connected to AC 230 V are physically separate from the
other terminals.
Warning!
The cable restraints on the housing base
must
be
used for the connections to terminals 19 … 21
(AC 230 V). The conductors must be secured with
cable ties (see diagram).
Ensure that the power is off before inserting or
removing plug-in terminals connected to a
mains voltage.
