2. Conformity with standards
The light fitting is suitable for use in zone 1, 21, 2 and 22
hazardous areas acc. to EN 60079-10 and IEC 61241-10.
The built-in EVG 05 fulfills the requirements of the draft IEC
60079-7 Ed. 4 (EOL) and the IEC 61347-2-3 (§17.2 and §17.3).
It has been designed, manufactured and tested according to
the state of the art and according to DIN EN ISO 9001: 2000.
All requirements of the standards are fully kept in mains
operation. In the event of interferences being emitted in emer-
gency operation, there will be a slight upper deviation from
the value defined in the standard in a certain frequency range.
That deviation does not entail any impairment of any other
apparatus, if the luminaire is duly operated.

4. Special functional features
Charging the battery
In mains operation the light fitting is charged by means of a
constant current charger. Charging takes place via the
unswitched external phase L to prevent an interruption, even
when the luminaire is switched off.
With regular operation of the light fitting the charging current
is measured so that a flat battery will have obtained apx. 90 %
of its rated capacity within 14 h. It is suitable for a continuous
charge of the battery.
In emergency operation a deep discharge protection with
reclosure preventing device monitors the battery voltage and
prevents the accumulators’deep discharge.
System modes
When voltage applies, the lamps in the light fitting can be
switched on and off with the light switch.
There are two system modes for emergency operation
1. Independent system mode:
If the terminals on the terminal block 2-3 (wiring diagrams 1
and 3) are bridged, there will be an automatic changeover to
emergency operation in the event of a mains failure.
On the eLLM92 pole mounted light fitting this bridge is
established on the terminals S1 and S2 (wiring diagram 2).
2. Dependent system mode
When removing the bridge 2-3 (wiring diagrams 1 and 3) the
emergency light function can be separately switched on and off
via a remote switch installed outside in the event of a mains
failure.
Connect the remote switch to terminal 2-3 (eLLK 92) or to S1
and S2 (eLLM 92).
Max. 10 luminaires can be connected to one remote switch
(wiring diagram 4).
Setting the emergency duration
1.5 hours:
Connect both conductors
under terminal 1.
3.0 hours:
Connect one conductor under terminal 1
and one conductor under terminal 0,
(wiring diagrams 1, 2 or 3).
5. Installation eLLK 92 ...NIB
The respective national regulations as well as the
general rules of engineering which apply to the in-
stallation and operation of explosion protected appara-
tus, will have to be observed!
Transport and storage of the luminaire is permitted in
original packing and specified position only!
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.
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°.
Mounting:
see fig. 1
The integrity of the fitting may be compromised if
the fixing centres are not correctly aligned, see fig.
10-12. When fixing the mounting accessories onto the light
fitting, observe the max. depth of thread of 12 mm!
Do not use too long screws!
I
nstalling the light output upwards additional protection
has to be assembled to avoid permanent water
accumulations at the protective bowl gasket area.
Accessories for mounting:
See CCH/CEAG catalogue.
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 (fig.
4 and 5).
Introduce the cable through the EEx cable entry (fig. 5).
Use both sealing inserts for cables from 8 to 12 mm Ø,
and the outer sealing insert only for cables from 12 to
17 mm Ø. Pay attention to the proper fit of the sealing
insert remaining in the cable gland.
Connect the conductors to the terminals
PE, N, L1, L, (L2, L3) in accordance with the terminal
marking (wiring diagrams, page 2). Also tighten vacant
terminals!
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 3.5 Nm). When closing the
gland with a blanking plug, always use both sealing in-
serts!
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 EEx blanking plugs!
5.1 Installation of the eLLM 92 NIB
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 [ 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 EEx cable entry (KLE) and
tighten it with the pressure screw of the cable entry
(torque of 3.5 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.
Inserting the lamp
Only use such lamps that have been certified for these
light fittings, see technical data and type label!
T12-lamps (Ø 38 mm) will be detected as faulty and will be
cut off by the EOL-circuit
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. 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 AC/DC
– measuring current:
max. 10 mA
Mind: There must no insulation measurement be
carried out between L and N, since that would de-
stroy 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 pre-
viously 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. Maintenance
The national regulations applicable to the mainte-
nance, servicing and test of apparatus for explo-
sive atmospheres as well as the general rules of
engineering will have to be observed!
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!
Lamp replacement: Keep replacement intervals as
specified by the lamp manufacturer!
Test of the emergency light function
Switch the luminaire off the mains voltage.
The emergency lamp (red lampholder) must light.
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.
Should the emergency lamp be extinguished within the
test period though the battery is fully charged, the latter
will have to be replaced by a new battery set.
Mind: The full battery capacity will be available after
approx. 3 charging/discharging cycles due to physical
behaviour.
Repair:
Prior to replacing or removing any components, observe
the following:
Cut the apparatus off the voltage before opening or
servicing it! Only use certified genuine CCH/CEAG
spare parts! (See CCH/CEAG spare parts list).
Subject to alteration or supplement of this product
series.
Regarding waste disposal, observe the relevant national
regulations! The plastic materials are marked with the
relevant labels.
