To ensure the required minimum degree of
protection, the cover screws shall be tightened
down.
Overtightening may impair the degree of
protection.

6.6 Putting into operation

Prior to putting the apparatus into operation, the
tests specified in the relevant national regula-
tions shall be carried out.
In addition to this, the correct functioning and
installation of the apparatus in accordance with
these operating instructions and other applicable
regulations shall be checked.
Warning: The maintenance and repair supply
socket distribution may only be put into
operation if a "hot work permit" has been
issued and if it has been ensured that no
potentially explosive gas atmosphere is
present!
If, when the socket distribution is put into
operation, the ELCB (RCD) trips immediately,
check the connected consumer units for an earth
fault. Eliminate any connections or insulation
faults between the neutral and the PE wire.
Check the plug for any damage before inserting
it into the socket.
The user must ensure that a uniform equipoten-
tial earth applies throughout when the plug and
socket system is being operated.
The incorrect installation and operation of
the maintenance and repair supply socket
distributions can entail the loss of warranty.

the specific application and shall be, determined
by the user dependent on the conditions of use.
The white test button "T" of the ELCB (RCD)
shall be operated once a month in the switched
on state. The ELCB (RCD) shall trip when the
test button is actuated (blue switch jumps to
"O" position).
If this is not the case, the protective function is
no longer guaranteed and the ELCB (RCD) shall
be replaced.
Warning: In the case of live socket distribu-
tions and when the enclosure cover is open,
the switching-on of the MCB or the function
test of the ELCB (RCD) shall be carried out
with special care by specialized personnel!
During servicing, special attention shall be given
to checking the parts on which the explosion
protection depends (e.g. intactness of the
flameproof components, the enclosure, the
seals and cable entries).
If, in the course of servicing, it is ascertained,
that repairs are necessary, section 8 of these
operating instructions shall be observed.
