Conformity with standards
The light fitting is suitable for use in hazardous
areas of zone 2 and 22 according
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.
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
Observe the respective national
regulations as well as the general rules of
engineering which apply to the installation
and operation of electrical apparatus
(IEC/EN 60079-14).
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!
T12-lamps (Ø 38 mm) 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)!
Installing the light output upwards
additional protection has to be assembled
to avoid permanent water accumulations
at the protective bowl gasket area.
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. Therefore
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)

Explosion protected light fittings zone 2 and zone 22
Series: KXB-......
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.
Caution: If an unsuitable tool is used,
frictional turning of the central locking
device can not be guaranteed and the
device may be damaged.
– 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 °.
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!
Accessories for mounting:
See ZUMTOBEL catalogue.
4.3
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. 3+4.
For power connection, use cables with copper
conductor.
– The air and creep distances inside the light are
designed for soiling level 2. (IEC/EN 60644,
IEC/EN 60598-1, IEC/EN 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
protective glass must be removed and
sealed with a certified sealing plug (test
torque 2,6 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 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 sealing insert
remaining in the cable gland.
– Plug the bared conductors to the terminals in
accordance with the terminal marking (see
wiring diagram, page 3).
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 such lamps that have been
certified for these light fittings, see
Technical data and type label!
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.
Option: automatic double-pole switch
while opening the protective bowl.
