1)
Intensive sun radiation in areas of high ambient temperatures
may cause inadmissible temperature rise inside of the
luminaire. This may result a decrease in lifetime of the
electronic ballast (EVG). Therefore those luminaires should be
switched off during daytime by a photocell control.
4. Installation
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!
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!
Installing 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.
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°.
) in
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.
-
Introduce the cable through the Ex 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 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 2). With single
connection of the terminal no bending (loop) of the
conductor required! Also tighten vacant terminals!
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 yellow
protective caps of the unused entries are to be
removed and the entries to be closed with certified
Ex blanking plugs!
Installation of the nLLM 09 ...
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, see
fig. 2, item 1.
-
Open the connecting compartment by folding
1)
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.
-
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
2
1.5 mm

pushed home into the opening of the light fitting,
6.0 mm
2
2
see fig. 2, item 4a.
-
Adjust the light fitting and screw down the
for max. 16 A
preassembled M 6 special screws, applying a
2
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 (3.5 Nm torque).
-
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.

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!
T12-lamps (Ø 38 mm) will be detected as faulty and
will be cut off by the EOL-circuit
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 vi-
sible. 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 compliance with these
operating instructions and other applicable regula-
tions!
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
(nLLM92..) 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 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 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
-
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!
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/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 material identifications.
