Maintenance/Servicing

The relevant national regulations which
apply to the maintenance/servicing of
electrical apparatus in explosive atmos-
pheres, shall be observed (IEC/EN 60079-17).
Before opening the enclosure make sure
that the apparatus is disconnected from the
voltage, or take the appropriate protective
measures.
The required maintenance intervals depend on
the respective 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.
Cleaning:
Because of the risk of an electrostatic
charge, the junction boxes shall only be
cleaned with a damp, non fibrous cloth or
sponge!
hen servicing the apparatus, particularly those
parts that are decisive for the type of protection
against explosion, will have to be checked (e. g.
intactness of enclosure, cable glands, efficacy
of the cover gaskets).
If during servicing repairs prove to be neces-
sary, section 8 of these operating instructions
will have to be observed.
