3. Conformity with standards
The light fitting is suitable for use in zone 1, 21,
2 and 22 hazardous areas acc. to
IEC/EN 60079-10-1 and IEC/EN 60079-10-2.
The light fitting is conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.
References to standards and directives in these
operating instructions always relate to the latest
version. Other additions (e.g. details relating to
the year) shall be observed.
4. Installation
The respective national regulations as
well as the general rules of engineering
which apply to the installation and opera-
tion of explosion protected apparatus will
have to be observed (IEC/EN 60079-14)!
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 / 8 x 58 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 (M8 x 18), observe the max. depth
of thread!
Do not use too long screws!
Accessories for mounting:
See CCH / EATON catalogue.
Mains connection
To open the connection box, turn the green han-
dle to its stop in the direction of arrow, then pull
it and fold down the flap, see fig. 5 and 6.
– Use sealing inserts 1, 2 and 3 for cables from
8 to 10 mm Ø, sealing inserts 1 and 2 for
cables from 10 to 13 mm Ø and sealing
insert 1 for cables from 13.5 to 17 .5 mm Ø.

– Connect the conductors to the terminals
PE, N, L1, (L, L2, L3) in accordance with
the terminal marking (see wiring diagram,
page 2+3). With single connection of the
terminal no bending (loop) of the conductor
required! Also tighten vacant terminals!
Use only fixed installed cables! If cable
glands of other manufacturer are used the
specifications regarding clamping and strain
relief have to be observed.
In case of unused cable entries, remove their
protective cover and close the entries with a
blanking plug (test torque see technical data).
When closing the gland with a blanking plug,
always use sealing inserts 1+2!
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 Ex blanking plugs! (min. IP 66)
Fitting the lamps:
Only use such lamps that have been
certified for these light fittings, see Technical
data and type label! Note! Observe the
safety instructions of the lamp manufacturer!
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.

5. Taking into operation
Prior to operation, check the light fitting
for its proper functioning and installation in
compliance with these operating instruc-
tions 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
appli cable to the maintenance, servicing and
test of apparatus for explosive atmospheres
e.g IEC/EN 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:
– 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!
7. Repair
Repairs that affect the explosion
protection, may only be carried out by CCH /
EATON or a qualified electrician (Competent
person) in compliance with the applicable
national rules (IEC/EN 60079-19).
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 / EATON spare parts
(see CCH / EATON spare parts list)!
8. Disposal/Recycling
When the apparatus is disposed of, the
respective national regulations on waste
disposal will have to be observed.
In case of disposal you can obtain additional
information from your Cooper Crouse-Hinds /
EATON branch.
Subject to modifications or supplement of the
product range.
