User manual

▶ Hold the new electronic unit by the top and the bottom,
and carefully slide it into the base module.
The electronic units are functionally coded
so that they can only be inserted into the ap-
propriate base module. If it is not possible to
insert a new electronic unit into the base mod-
ule, check if the combination is correct and if
there is a possible mix-up.
Inserting the new electronic unit
▶ Fold the connector frame back so that it closes and clicks
into place.
▶ In case of replacement during operation: Pay attention to
the collective error LED (SF) on the fieldbus coupler.
Only when this doesn't light up any more, the new elec-
tronic unit has been recognised and the next electronic
unit is able to be pulled out.
