7 Maintenance / Servicing
The relevant national regulations which apply to the maintenance/

Before opening the enclosure make sure that the equipment is
disconnected from the voltage, or take the appropriate protective
measures.
In case of intrinsically safe circuits, working is permitted while voltage
applies.
The required maintenance intervals depend on the specific application and
will therefore have to be determined by the user dependent on the
conditions of use.
When servicing the apparatus, particularly those parts that are decisive for
the type of protection against explosion, will have to be checked (e.g.
intactness and tightness of the enclosure, efficacy of the gaskets and the
cable entries).
If during servicing, repairs prove to be necessary, section 8 of these
operating instructions will have to be observed.
