5.4 Connection Battery nLLK 08... N 1/6
The battery is cut of for delivering. Connect the
battery before taking into operation.
- Open the second reflector flap. (fig. 3)
- fasten unplugged battery wire. (fig. 4-6)
securely onto the connector.
- Observe the polarity of the Battery. (fig 5)
5.5 Connection Battery
nLLK 08... N 2/6
The battery is cut of for delivering. Connect the
battery before taking into operation:
Open the light fitting protective bowl
before opening the battery compartment.
This interrupts the emergency lighting circuit.
- Unscrew the battery compartment cover
(fig. 14).
- Connect cables on the connectors.
- Close battery-box in reverse order.
5.6 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. 19 and 20.
T12 lamps (Ø 38 mm) are supplied by the EOL
circuit detected as faulty and switched off!
Lights with T12 lamps (Ø 38 mm) must be
installed with mechanical protection and
marked accordingly.
6. 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 AC/DC
- measuring current: max. 10 mA
- Only operate the light fitting with complete
closed protective bowl.
- The battery is not complete full charged in
delivery condition.
- To balancing the LED display to the battery
capacity, the battery have to be charged 14
h before the first operation.
- After that, release a function test of the
emergency light connection, see 7.1.1.
Maintenance, function test.
7. Function
7.1 Emergency operation
The duration of the emergency operation is
factory side fixed and can not be adjusted.
The emergency operation will automatically
stated when mains supply failed or the charging
line L is switched off. The green marked
emergency lamp will operate on battery mode.
7.1.1 Function test emergency light
Switch off the mains supply from light fitting.
The green marked emergency lamp will operate.
A function test should not exceed the following
test periods:
Battery set for 1,5 h emergency light: 60 min.
Battery set for 3,0 h emergency light: 120 min.
Should the emergency lamp be extinguished
within the test period though the battery is fully
charged, the latter will have to be replaced by a
new battery set.
7.2 Charging
At temperatures below -5°C and above +35°C
the battery will not be fully charged for
electrochemical reasons.
Note: New batteries will reach their total useful
capacity only after 3 charging/discharging cycles.
8. Maintenance
Observe the national regulations
applicable to the maintenance, servicing and
test of electrical apparatus as well as the
general rules of engineering
(e.g. IEC/EN 60079-17, IEC/EN 60079-19)!
8.1 Servicing
When servicing, in particular those components
that affect the type of 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 cloth or sponge!
Only use customary household washing-up
liquid diluted in water as specified! The water
temperature may be max. 50ºC. After that,
rinse with clear water to prevent the risk of
tension cracks in the protective bowl!
Lamp replacement: Keep replacement intervals
as specified by the lamp manufacturer!
9. Repair
Prior to replacing or removing any
components, observe the following:
Disconnect the power supply to the equip-
ment before maintenance / repair.
Disconnect the power supply to the equip-
ment before maintenance / repair.
Only use certified genuine CCH / EATON spare
parts! (See CCH / EATON spare parts list).
Lamp exchange must be carried out while
energy is switched off.
Option: automatic double-pole switch while
opening the protective bowl.
9.1 Battery change general
Transport the battery only in original
packing through potentially zones 2/22 with
explosive atmospheres.
Protect against shocks.
- Prior to opening the enclosure, it is necessary
to ensure that the voltage supply has been
isolated.
- Only use certified genuine CCH / EATON
spare parts.
Explosion protected light fittings zone 2 and zone 21/22
