Conformity with standards
The light fitting is suitable for use in hazardous
areas of zone 2, 22 according IEC/EN 60079-10-
1 and -2.
They have been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001:2015 and
EN ISO/IEC 80079-34:2011.
The light fitting is conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.
4.
Installation
Observe the respective national
regulations as well as the general rules of
engineering which apply to the installation
and operation of electrical apparatus!
Transport and storage of the luminaire is
permitted in original packing and specified
position only!
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!
T5-lamps (Ø 16 mm) at their life´s end, will
be detected as faulty and will be cut off by
the EOL-circuit.
In special environment condition it could be
necessary to use a breathing and drainage plug
(GHG960 1954 R0002)!
Mind
For handrail mounting (e.g. mounted at 45°) we
recommend replacing the existing cover of the
locking bolt with the version part
no 22216904000.
In such a case the cover should be fixed with
its hinges on the top part of the housing.
Due to the high ingress protection condensa-
tion cannot be avoided completely. Therefor we
recommend the use of a breather plug in
outdoor areas with high humidity and high
ambient temperatures.
(e.g. M20 order no. GHG9601954R0014 or
M25 order no. GHG9601954R0002)
4.1
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°.
Explosion protected light fittings
Series: nLLK 10
4.2
Mounting dimensions see fig. 2
When fixing the mounting accessories
onto the light fitting, observe the max.
depth of thread of 14 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.
4.3
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+5.
For power connection, use cables with copper
conductor.
– The air and creep distances inside the light are
designed for soiling level 2.
(EN/IEC 60644, EN/IEC 60598-1,
EN/IEC 60079-0/6.1 Note 3)
– When connecting the light to a flexible cable,
ensure the correct strain relief (trumpet screw
with at least IP66 protection class).
Only cable entries and sealing plugs certified
to 2014/34/EU may be used.
To guarantee protection type „nA" , use only
cable entries with at least IP66 protection
class.
The corresponding manufacturer's Operating
Manual must be observed.
Where cable entries are not used, the pro-
tective glass must be removed and sealed
with a certified sealing plug (test torque
3.5 Nm). If sealing with a sealing plug,
always use both sealing inserts! (IP66).
Unused threaded holes for cable entries are
sealed with a certified screw-plugscrew
(IP66).
– Introduce the cable through the 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 sealing insert remaining
in the cable gland.
– Plug the bared conductors to the terminals
in accordance with the terminal marking
(see wiring diagram, page 2).
Stripping length 2.5 mm²: 8 - 9 mm
– When screw-terminals are used also tighten
vacant terminals! With single connection of
the terminal no bending (loop) of the
conductor required!
– If screw terminals are fitted, unused terminals
must also be tightened! With single-compo-
nent terminals, the wires do not need to be
bent (loop)!
4.4
Fitting the lamps
Only use HE lamps that have been
certified for these light fittings, see Technical
data and type label!
The bi-pin lamp (G5) is to be inserted to its stop
into both holders so that both pins on either
side of the lamp engage in the holder. Then turn
the lamp to its lock-in position, see fig. 8.
Attention! Lamp exchange must be
carried out while energy is switched off.
Option: automatic double-pole switch while
opening the protective bowl.
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 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
6.
Maintenance
Observe the national regulations
applicable to the maintenance, servicing
and test of electrical apparatus as well
as the general rules of engineering
(e.g. EN/IEC 60079-17)!
Servicing
When servicing, in particular those components
that affect the type of 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 cloth or sponge!
Only use customary household washing-up
liquid diluted in water as specified! The water
temperature may be max. 50ºC. 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.
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! All components are
marked with relevant material signs.
