For skilled electricians and trained person-
nel in accordance with national legislation, including
the relevant standards and, where applicable, in
acc. with IEC 60079-17 on electrical apparatus for
explosive atmospheres.
The light fitting is not suitable for use in
hazardous areas of zone 0 , zone 1 and zone 20!
The light fitting must not be use while
excessive deposit of dust (≥ 50 mm, accd. EN
50281-1-2) exist.
The technical data indicated on the light fitting
are to be observed!
Changes of the design and modifications to the
light fitting are not permitted!
The light fitting shall be operated as intended
and in undamaged and perfect condition!
Only genuine Zumtobel spare parts may be
used for replacement!
Repairs may only be carried out by Zumtobel or
a qualified "electrician"!
Do not keep these operating instructions inside
the light fitting during operation!
The national safety rules and regulations for
prevention of accidents and the following safety
instructions which are marked with an (
these operating instruction, will have to be
observed!
2. Conformity with standards:
This explosion protected light fitting meets the
requirements of the EC directive „Apparatus and
protective systems for its intended use in hazardous
areas (94/9/EC) and electromagnetic compatibility
(2004/108/EEC).
It has been designed, manufactured and tested
according to the state of the art and according to DIN EN
ISO 9001: 2000. The light fitting is suitable for use in
hazardous areas of zones 2 and 22 according
IEC 60079-14 and IEC 61241-10.

Therefore those luminaires should be switched off
during daytime by a photocell control.

4. Installation
Observe the respective national regulations as
well as the general rules of engineering which
apply to the installation and operation of elec-
trical apparatus! Transport and storage of the
luminaire is permitted in original packing and speci-
fied 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+4.
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
) in
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!
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 Zumtobel catalogue.
Mains connection KXB ...
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.
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!
Attention
In case of unused cable entries, remove their
protective cover and close the entries with a
blanking plug (test-torque of 3.5 Nm). When

The bi-pin lamp (G13) 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.

6. Maintenance
trical apparatus as well as the general rules of engi-
neering (e.g. 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!
Repair
ing it or carrying out repairs! Only use certified
genuine Zumtobel spare parts! (See Zumtobel 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.
