Mains Connection; Fitting The Lamps - Eaton CROUSE-HINDS Série Mode D'emploi

4.2 Opening and closing the light fitting
– Turn the central locking device with a box
spanner (opening of the spanner SW 13)
through 90° to its lock-in position and fold
down the protective bowl, see fig. 3.
Caution:
If unsuitable tools are used, a strong
tightening of the central locking system is
not guaranteed and it will be damaged.
– Fit in and remove the protective bowl acc. to
fig. 6 and 7.
– The protective bowl can, at option, be hinged
on either side.
– To close the light fitting, press the protective
bowl tightly onto the luminaire housing and
turn the central locking device through 90°.
4.3

Mains connection

To open the connection box, turn the green
handle to its stop in the direction of arrow,
then pull it and fold down the flap,
see fig. 4 and 5.
For power connection, use cables with copper
conductor.
– Introduce the cable through the Ex cable
entry, see fig. 5. Use sealing inserts 1,2 and 3
for cables from 8 to 10 mm Ø, sealing inserts 1
and 2 for cables from 10 to 13 mm Ø and
sealing insert 1 for cables from 13.5 to 17.5 mm Ø.
Pay attention to the proper fit of the
remaining sealing insert in the cable gland.
– Connect the conductors to the terminals
PE, N, L1, (L, L2, L3) in accordance with
the terminal marking (see wiring diagram,
page 3). With single connection of the
terminal no bending (loop) of the conductor
required! Also tighten vacant terminals!
– When using multi- or fine-wire connection
cables, the wire ends must be provided with
wire end sleeves or cable lugs.
Attention:
In case of unused cable entries, remove their
protective cover and close the entries with a
blanking plug .
When closing the gland with a blanking plug,
always use sealing inserts 1+2!
When metal cable entries are used, the yellow
protective caps of the unused entries are to be
removed and the entries to be closed with
certified Ex blanking plugs!
4.3.1 Installation of the eLLM 92 ...
The pole mounted light fitting is mounted and
installed in the following order:
– Unscrew the three recessed head screws in
the cover of the pole connecting compart-
ment, see fig. 2, item 1.
– Open the connecting compartment by folding
down the cover, see fig. 2, item 2.
– Pull the stay shackle of the cable entry socket
up to its stop and take off the cover plate,
see fig. 2, item 3.

Explosion protected light fittings
Series: eLLK 92, eLLS 08, eLLM 92
– Remove the cable entry sockets from the
guiding grooves in in the connecting
compartment.
– Then the pole mounting tube or the tube of
the wall socket of 42 mm Ø each
(fig. 2, item 4) is pushed home into the
opening of the light fitting, see fig. 2, item 4a.
– Adjust the light fitting and screw down the
pre assembled M 6 special screws, applying
a torque of 3.0 Nm, see fig. 2, item 5.
– Introduce the cable through the tube and
strip the insulation to the required length.
– Introduce the cable through the Ex cable
entry (KLE) and tighten it down with the
pressure screw of the cable entry.
– The complete support (with the cable being
introduced) is put into the guiding grooves of
the pole mounted light fitting, see fig. 2, item 6.
– Lock the support with the stay shackle,
see fig. 2, item 3.
– Insert the cable into the pull-relief and tighten
it down, see fig. 2, item 7.
– Then connect the cable in accordance with
the terminal marking.
4.4

Fitting the lamps

Observe the safety instructions of the lamp
manufacturer!
Only use such lamps that have been
certified for these light fittings, see technical
data and type label!
4.4.1 Single-pin lamp (Fa6)
First insert one side of the lamp into the
lampholder. Then pull the opposite lampholder
slightly outwards and insert the lamp, see
fig. 8.1 and 9.1.
4.4.2 Bi-pin lamp (G13)
The lamp is to be inserted to its stop into both
holders, see fig. 8, so that both pins on either
side of the lamp engage in the holder.
Then turn the lamp through 90° to its lock-in
position, see fig. 9, the green surface in the
holder getting visible. Now the lamp is secured
against falling out.
5. Taking into operation
Prior to operation, check the light fitting for its
proper functioning and installation in compli-
ance with these operating instructions and
other applicable regulations!
Only carry out insulation measurements
between PE and the external conductor L1
(L, L2, L3) as well as between PE and N.
– measuring voltage: max. 1 kV DC
– measuring current: max. 10 mA
Then the luminaire will have to be closed. The
terminal compartment of the pole mounted
light fitting (eLLM92..) is again to be covered
with the cover plate that was previously
removed. To that effect, pull up the stay
shackle of the cable entry socket (fig. 2, item 3)
and clamp down the cover plate and the cable
entry socket with the stay shackle. Again screw
down the cover of the terminal compartment
with the three recessed head screws.
6. Maintenance
Observe the national regulations
applicable to the maintenance, servicing and
test of apparatus for explosive atmospheres
e.g IEC/EN 60079-17 and IEC/EN 60079-19 as
well as the general rules of engineering!
6.1 Servicing:
When servicing, in particular those components
that affect the explosion protection, will have to
be checked, e. g.:
– Housing and protective bowl for any cracks
or damages.
– Gaskets for their perfect condition.
– Terminals and blanking plugs for their firm fit.
– Because of the risk of an electrostatic charge,
the light fitting shall only be cleaned with a
damp, non-fibrous cloth or sponge!
Only use customary household washing-up
liquid diluted in water! The water temperature
may be max. 50 °C.
After that, rinse with clear water to prevent the
risk of tension cracks in the protective bowl!
6.2 Lamp replacement
– Lamp replacement: Keep replacement
intervals as specified by the lamp
manufacturer!
– Lamp replacement can be done without cut
off the luminaire from mains supply, because
an all pole switch will isolate the lampholders
while opening the protective bowl.
Notice: Observe national standards or
directions for use which can be divergent to
this!
7. Repair
Prior to replacing or removing any components,
observe the following:
Cut the apparatus off the voltage before
opening it or carrying out repairs!
Only use certified genuine CCH / EATON spare
parts! (see CCH / EATON spare parts list).
8. Disposal/Recycling
When the apparatus is disposed of, the respec-
tive national regulations on waste disposal will
have to be observed.
In case of disposal you can obtain additional
information from your Cooper Crouse-Hinds /
EATON branch.
In order to facilitate the recycling of individual
components, plastic parts are provided with the
identification mark of the plastic material used.
Subject to modifications or supplement of the
product range.
