5.3 Installation eLLM 92...A LED 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. 1, item 1).
– Open the connecting compartment by folding down the cover
(fig. 1, item 2).
– Pull the stay shackle of the cable entry socket up to its stop and take off
the cover plate (fig. 1, 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 [
each (fig. 1, item 4) is pushed home into the opening of the light fitting
(fig. 1, item 4a).
– Adjust the light fitting and screw down the pre assembled M 6 special
screws (torque of 3.0 Nm, fig. 1, 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.
– The complete support (with the cable being introduced) is put into the
guiding grooves of the pole mounted light fitting (fig. 1, item 6).
– Lock the support with the stay shackle
(fig. 1, item 3).
– Insert the cable into the pull-relief and tighten it (fig. 1, 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).
5.4 LED module inserting
As delivered, the LED module (CML 17ATEX3243U /
IECEx CML 17 .0137U) is attached to the light fitting.
Use only approved CCH / EATON stock items in stock!
Do not damage the LED module reflector.
Only transport the LED module in its original packing.
When removing from the packaging and fitting in to the light fitting,
only handle the unit by the plastic parts at the ends (Fig 6a).
Insert the LED module in the G13 versions of linear luminaire fig. 7 .
Snap the module into the G13-sockets of the light fitting, whereby a
distinct clicking sound can be heard (Fig. 2.8).

Taking into operation

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. 1,
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 compart-
ment with the three recessed head screws.

Explosion protected emergency light fittings
Series: eLLK(M)(S)92 LED 400A(800A) NE
– 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!
7.2
Switch the luminaire off the mains voltage.
The emergency operation LED row (row with green spot) must light up
The emergency function lasts at least 1 min..
A function test should not exceed the following test periods:
Battery set for 1.5 h emergency light: 60 min.
Battery set for 3.0 h emergency light: 120 min.
Note: See the enclosed operating instructions for eBK12, No. 3 2211 000 172
for further information on the automatic function and operation duration
test
8.
Prior to replacing or removing any components, observe the
following:
Cut the apparatus off the voltage before opening or servicing it!
The battery have to be removed.
Repairs and overhaul may only be carried out with genuine Cooper
Crouse-Hinds / EATON spare parts.
In the event of damage, replacement of these components is
mandatory. In case of doubt, the respective apparatus shall be sent
to CCH / EATON for repair.
Reconstruction or modifications to LED module are not permitted.
Repairs that affect the explosion protection, may only be carried
out by CCH / EATON or a qualified electrician in compliance with the
applicable national rules (IEC/EN 60079-19).
