item 2, can be removed from the base, item
1, by turning it anticlockwise.
Warning: The cover shall be safeguarded
against falling off.
The connection of explosion-protected
flameproof enclosures and distributions
may only be carried out by specialists.
The permissible ambient temperature, the
terminal cross section and the self-
heating of the apparatus, that is mainly
caused by the power dissipation are to be
observed to ensure that the temperature
class stated on the type label of the
apparatus is maintained.
Explosion-protected empty housings
must be certified after assembly by an
inspection station or for the examination
of entitled persons.

Before screwing in the cover thread is to be
greased. Preferably with type of fat:
Renocal, university Universities of 2, -50°C to
+100°C, FN 745/94, DIN VOLKSWAGEN tl
745).
The cover of the enclosure have to be
turned down clockwise into the cover-
base, till the stop.
To fixing of the enclosure-cover, the fixing-
screw (Pos.3, Pic 1&2), or the switch in the
enclosure-cover, have to be used.

apparatus and of the built-in components
(measuring instruments, signal lamps,
pushbuttons, etc.) shall be checked in
accordance with these operating instructions
and other applicable regulations.
Warning: Only certified apparatus may be
put into operation
If the Explosion-protected flameproof
enclosures interior temperatures under -
20 °C the system mustn´t be operated.
If lower temperatures are present, the
Explosion-protected flameproof
enclosures must become pre-heated with
a suitable certified heating on over -20 °C.
If an uncertified heating is used to pre-
heat the flameproof enclosures inside
temperature on over -20 °C,explosive
atmosphere mustn´t to be present.

Maintenance / Servicing
The relevant national regulations which apply
to the maintenance/repair of electrical
apparatus in explosive atmospheres, will have
to be observed (in Germany e.g. ElexV,
VDE 0105 part 9).
Before opening the enclosure make sure that
the apparatus is disconnected from the
voltage, or take the appropriate protective
measures.
The necessary intervals between servicing
depend upon the specific application and
shall be stipulated by the operator according
to the respective operating conditions.
1. Flameproof enclosures
Visual inspection of the cover thread.
The thread shall not be treated or varnished!
Any damaged parts shall be replaced
immediately using original parts or the
damaged parts shall be repaired by the
manufacturer.
2. Connection and bus bar boxes
