Taking into operation

The electrical connection of the device may only be carried out by skilled
staff (IEC/EN 60079-14).
Prior to taking the apparatus into operation, the tests specified in the
relevant national regulations will have to be carried out.
Apart from that, the correct functioning and installation of the apparatus
in accordance with these operating instructions and other applicable
regulations will have to be checked.
Incorrect installation and use of the junction boxes can invalidate
the guarantee.

The required maintenance intervals are set according to their
application and should therefore be determined depending on the
conditions of use.
Before opening the enclosure make sure that the apparatus is
disconnected from the voltage, or take the appropriate protective
measures.
In case of intrinsically safe circuits, working is permitted while voltage
applies.
The relevant national regulations which apply to the maintenance/
servicing of electrical apparatus in explosive atmospheres, shall be
observed (IEC/EN 60079-17).
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 of enclosure, cable glands, efficacy of the cover gaskets).
If during servicing repairs prove to be necessary, section 8 of these
operating instructions will have to be observed.

Repairs and overhaul may only be carried out with genuine COOPER
CROUSE-HINDS / CEAG spare parts.
Repairs that affect the explosion protection, may only be carried
out by COOPER CROUSE-HINDS or a qualified electrician (Compe-
tent person) in compliance with the applicable national rules
(IEC/EN 60079-19).
For replacement and repair only original parts from COOPER
CROUSE HINDS-/ CEAG may be used.
Modifications to the apparatus or changes of its design are not permit-
ted, except for the mounting of additional cable entries and the installa-
tion of supply terminals in accordance with the approval of the apparatus.
