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-Declara-
tion 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.

Special functional features
Charging the battery
In mains operation the light fitting is charged by means of a constant
current charger. Charging takes place via the unswitched external phase L
to prevent an interruption, even when the luminaire is switched off. With
regular operation of the light fitting the charging current is measured so
that a flat battery will have obtained approx. 90% of its rated capacity
within 14 h. It is suitable for a continuous charge of the battery.
In emergency operation a deep discharge protection with reclosure
preventing device monitors the battery voltage and prevents the
accumulators deep discharge.
System modes
When a voltage is applied, the LED module in the light fitting can be
switched on and off with the light switch.
There are two system modes for emergency operation
1. Independent system mode:
If the terminals on the terminal block 3-4 (wiring diagrams) are bridged,
there will be an automatic changeover to emergency operation in the
event of a mains failure.
2. Dependent system mode
When removing the bridge (B), terminal 3-4 the emergency light function
can be separately switched on and off via a remote switch installed
outside in the event of a mains failure. Connect the remote switch to
terminal 3-4. Max. 10 luminaires can be connected to one remote switch
(wiring diagram).
Setting the emergency duration:
1.5 hours:
connect Bridge "C" between terminals 5 and 6
3.0 hours:
remove Bridge "C" between terminals 5 and 6.
Explosion protected emergency light fittings
Series: KXA-2 2600 NE, KXA-2 5100 NE
5.
The respective national regulations as well as the general rules of
engineering which apply to the installation and operation of
explosion protected apparatus, will have to be observed!
Transport and storage of the luminaire is permitted in original
packing and specified position only!
Note: Installing the light output upwards additional protection
has to be assembled to avoid permanent water accumulations at the
protective bowl gasket area.
Note:
For handrail mounting (e.g. mounted at 45°) we recommend replacing the
existing cover of the locking bolt with the version part no 22216904000.
5.1
– 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. 5 and 6.
– The protective bowl can, at option, be hinged on either side.
– Then the luminaire will have to be closed. When closing the protective
bowl, pull it out slightly to prevent the catch mechanism from touching
the LED module reflector (fig. 8a).
– To close the light fitting, press the protective bowl tightly onto the
luminaire housing and turn the central locking device through 90°.
The integrity of the fitting may be compromised if the fixing
centres are not correctly aligned, see fig. 9 - 10. 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.
5.2
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 (fig. 3 and 4).
For power connection, use cables with copper conductor.
– Introduce the cable through the Ex cable entry (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 sealing insert remaining in the cable
gland.
– Connect the conductors to the terminals PE, N, L1, L, (L2, L3) in
accordance with the terminal marking (wiring diagrams, page 3). Also
tighten vacant terminals!
Note: The charging conductor L and the luminaire's mains
connection must always be connected to the same external
conductor of the mains supply!
Attention: In case of unused cable entries, remove their protective
cover and close the entries with a blanking plug. When closing the
gland with a blanking plug, always use both sealing inserts! 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!
