Mind: The charging conductor L and the luminaire's mains
connection must always be connected to the same external
conductor of the mains supply!
Attention: In case of unused cable entries, remove their protective
cover and close the entries with a blanking plug (torque of 2,6 Nm).
When closing the gland with a blanking plug, always use both
sealing inserts! When metal cable entries are used, the protective
caps of the unused entries are to be removed and the entries to be
closed with certified Ex blanking plugs!

Installation eLLM 92 NE
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 compartment (fig. 2, item 1).
– Open the connecting compartment by folding down the cover
(fig. 2, item 2).
– Pull the stay shackle of the cable entry socket up to its stop and take
off the cover plate (fig. 2, item 3).
– Remove the cable entry sockets from the guiding grooves 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 (fig. 2, item 4a).
– Adjust the light fitting and screw down the preassembled M 6 special
screws (torque of 3.0 Nm, 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 with
the pressure screw of the cable entry (torque of 3.0 Nm).
– The complete support (with the cable being introduced) is put into the
guiding grooves of the pole mounted light fitting (fig. 2, item 6).
– Lock the support with the stay shackle (fig. 2, item 3).
– Insert the cable into the pull-relief and tighten it (fig. 2, item 7).
– Then connect the cable in accordance with the terminal marking.
– If multi- or fine-wire connecting cables are used, the wire ends will
have to be handled in acc. with the applicable national and international
rules. (e.g. use of sleeves for strands).

Inserting the lamp
Only use such lamps that have been certified for these light
fittings, see technical data and type label!
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
(fig. 8.1 and 9.1).
Bi-pin lamp (G13)
The lamp is to be inserted to its stop into both holders (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 (fig. 9), the green
surface in the holder getting visible. Now the lamp is secured against
falling out.

6.
Prior to operation, check the light fitting for its proper functioning
and installation in compliance 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
Mind: There must no insulation measurement be carried out
between L and N, since that would destroy the electronics (mains
input fuse in the VE unit).
– Then the luminaire will have to be closed. The terminal compartment of
the pole mounted light fitting (eLLM 92..) 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.
– Switch on the mains voltage and then the light fitting.
– Leave the light fitting switched on for at least
14 hours so that the battery will be recharged.
– After that, release a function test of the emergency light connection,
see 7 . Maintenance, function test.
7.
The national regulations applicable to the maintenance, servicing
and test of apparatus for explosive atmospheres as well as the
general rules of engineering will have to be observed
(IEC/EN 60079-17 and IEC/EN 60079-19)!
7.1
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!
– Lamp replacement: Keep replacement intervals as specified by the lamp
manufacturer!
The battery is monitored via the automatic test cycles and conditioned
(get / regenerate the battery capacity).
