Enclosure cover monitoring
Enclosure cover monitoring is fitted at the intermediate position of the command points. The
plunger is screwed onto the enclosure cover. The module attachment is snapped into the
intermediate position on the enclosure base and fitted with 1 NO (normally-open) contact
module. The entire circuit is routed via this contact module. When the enclosure has been
correctly screwed together, the circuit closes and the controlled device can be operated.
Please note that the enclosure cover monitoring cannot be used with the raised enclosures
with one command point (3SU18.1-1AA00-1AA1).
