Introduce the cable through the Ex cable
entry, see fig. 4.
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 cable gland.
-
Connect the conductors to the terminals
PE, N, L1, (L, L2, L3) in accordance with the
terminal marking (see wiring diagram,
page 2. With single connection of the
terminal no bending (loop) of the conductor
required!
Also tighten vacant terminals!
-
When using multi- or fine-wire connection
cables, the wire ends must be provided with
wire end sleeves or cable lugs.
Attention
In case of unused cable entries, remove
their protective cover and close the entries
with a blanking plug (torque of 3.5 Nm).
When closing the gland with a blanking plug,
always use both sealing inserts!
When metal cable entries are used, the yellow
protective caps of the unused entries are to be
removed and the entries to be closed with
certified Ex blanking plugs! (min. IP 65)

Fitting the lamps
Consider 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!
4.4.1 Bi-pin lamp (G13)
The lamp is to be inserted to its stop into both
holders, see fig. 6, 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. 7 , the green surface in the
holder getting visible. Now the lamp is secured
against falling out.
Explosion protected light fittings series: KXA-2...
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 DC
– measuring current: max. 10 mA
Then the luminaire will have to be closed.
6.
Maintenance
Observe the national regulations applica-
ble to the maintenance, servicing and test of
apparatus for explosive atmospheres e.g
IEC/EN 60079-17 and IEC/EN 60079-19 as well
as the general rules of engineering!
6.1
Servicing
When servicing, in particular those components
that affect the explosion 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, non-fibrous cloth or sponge!
Only use customary household washing-up liquid
diluted in water!
The water temperature may be max. 50°C.
After that, rinse with clear water to prevent the
risk of tension cracks in the protective bowl!
6.2
Lamp replacement
-
Lamp replacement: Keep replacement
intervals as specified by the lamp manufactur-
er!
-
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
Prior to replacing or removing any
components, consider the following:
Switch the apparatus off the voltage before
opening it or carrying out repairs! Only use
certified genuine ZUMTOBEL spare parts
(see appropriate 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 ZUMTOBEL branch.
Subject to modifications or supplement of the
product range.
