Conformity with standards

The luminaire is suitable for use in zone 1, 2, 21
and 22 hazardous areas acc. to
EN/IEC 60079-10-1 and EN/IEC 60079-10-2.
The luminaire is conform to the standards
specified in the EU-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 Ex-Lite
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!
4.1 Opening and closing the light fitting
– Unscrew the four recessed head screws of
the cover
– Remove the protective cover.
4.2 Installation of the fitting
Warning:
Hazard due to electrostatic charges!
Luminaire must not be installed in the
vicinity of charge-generating processes!
The luminaire shall be fitted by using the four
mounting clips with suitable fixing screws
(Ø 5 mm, fig. 1) onto a suitable surface.
4.3 Mains connection
After opening the cover unscrew the four
screws of the LED-printed board (fig.1).
Let down the LED-printed board (fig.2).
The printed board is protected against falling
down by a safety tie.
Pass the cable through the certified Ex cable
entry M 25 x 1,5.
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.
Pay attention to the proper fit of the remaining
sealing insert in the certified cable gland.
In case of unused cable entries, remove their
protective cover and close the entries with a
blanking plug (torque of 3.0 Nm).
When closing the gland with a blanking plug,
always use sealing inserts 1+2!

Explosion protected LED exit luminaire
Series: Ex-Lite, Ex-Lite LT Ex-Lite V-CG-S, Ex-Lite 24 V
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 IP 66!
Only fix laid cable may be used for
connection! If cable glands from other
manufacturer are used the instructions
regarding strain relief and clamping capacity
must be observed!
Connect the conductors to the terminals L, N
and PE in accordance with the terminal
marking (see fig. 3).
Remont the LED-printed board into the
housing. Take care not to pinch any conductors.
Take care not to pinch any conductors. Install
the protective cover with the four screws
(Test torque 2.4 Nm).
4.4 Changing of the legend
To install the correct legend open the 4 scews
(fig. 4) together with the 2 brackets at the cover
frame. Remove the old legend. Put the selected
new legend onto the protective glas panel. Fix
the legend with the two brackets and scews on
the frame. Close the frame onto the enclosure
(fig. 5).
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
(IEC/EN 60079-14)!
Only carry out insulation measurements
between PE and the external conductor L as
well as between PE and N.
– measuring voltage: max. 1 kV AC/DC
– measuring current: max. 10 mA
Mind: There must no insulation measure-
ment be carried out between L and N, since
that would destroy the electronics (mains
input fuse in the unit).
5.1 Monitoring (only Ex-Lite V-CG-S)
The V-CG-S module monitors and indicates to
the connected CEAG emergency supply system
the operation of the supply unit circuit and the
function of min. 50 % of the installed LEDs.
The V-CG-S module allows single monitoring of
these luminaires in CEAG emergency lighting
systems. The switching mode (maintained/
non-maintained and switched emergency
luminaires) is freely programmable and mixed
operation up to 20 addresses in a single circuit
is possible.
5.2 Addressing
Before fitting the cover, the addressing of the
individual luminaires is to be carried out. The
desired address (fig.6, 1 - 20) is set on the
address switch by means of a suitable screw
driver (Arrowhead to No., fig. 6). If the luminaire
should not be monitored the code 0/0 has to be
selected.
The standing luminaire Ex-Lite and is not
equipped with monitoring circuit and can not be
addressed.
6 Maintenance/Servicing
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!
When servicing, in particular those components
that affect the explosion protection, will have to
be checked, e. g.:
– Housing and protective glas for any cracks or
damages.
– Gaskets for their perfect condition.
– Terminals and blanking plugs for their firm fit.
7 Repair/Overhaul
Repairs that affect the explosion
protection, may only be carried out by CCH/
CEAG or a qualified electrician 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 CEAG/CCH spare
parts (see CEAG/CCH 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.
