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.
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.
Max. 10 luminaires can be connected to one remote switch
(wiring diagram page 3).
Attention! Remote switch must be potentional-free, do
not connext to external voltage!

5. Installation eLLB 20 ...NIB
The respective national regulations as well as the
general rules of engineering which apply to the
installation and operation of explosion protected
apparatus 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
unscrew the slotted screws on the cover pane and open
the pane (see fig. 1 and 2)
To close the glass pane, press tightly onto the luminaire
housing and hand-screw (Test torque 1.5 Nm)
Mounting dimensions: see fig. 9
Recessed ceiling installation
For recessed ceiling installation into sufficient capable ceilings
the mounting lugs (4 x 18 W/6 x 36 W have to be screwed with
an Allen key 4 mm through the aperture in the mounting frame.
The apertures have to be sealed with blanking plugs after be
used.
Observe the correct ceiling cutout!
When fixing the mounting accessories onto the light fitting,
observe the max. depth of thread!
Do not use too long screws!
Accessories for mounting: See 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, see
fig. 5 and 6.
Introduce the cable through the EEx cable entry, see
fig. 5. Use both sealing inserts for cables from 8 to 12
mm, and the outer sealing insert only for cables from
12 to 17 mm. Pay attention to the proper fit of the

no bending (loop) of the conductor required! 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 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
EEx blanking plugs! (min. IP 66)

the keyway on the coupler. Then turn the plug to the right through
approx. 30° until it reaches the stop.
Insert plug into coupler until it reaches the final stop.
Observe the relevant CEAG instruction GHG 570 7001 P0002!
(see Internet using" www.ceag.de")
Tighten the coupling nut on the connected plug and
socket.
Fitting the lamps
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.
Bi-pin lamp (G13)
The lamp is to be inserted to its stop into both holders, see
fig. 7, 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.
8, 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 destroy the elec-
tronics (mains input fuse in the VE unit).
Then the luminaire will have to be closed.
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
Observe the national regulations applicable to the
maintenance, servicing and test of apparatus for
explosive atmospheres e.g IEC 60079-17 as well as
the general rules of engineering!
Servicing
When servicing, in particular those components that affect the
explosion protection, will have to be checked, e. g.:
Housing and cover pane for any cracks or damages.
Gaskets for their perfect condition.
Terminals and blanking plugs for their firm fit.
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 serv-
icing it! Only use certified genuine CEAG spare parts! (See
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
material identifications.
