In case of unused cable entries, remove their protective cover
and close the entries with a blanking plug (torque of 2.6 Nm).
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!
(min. IP 65)

Fitting the lamps:
Only use such lamps that have been certified for these light
fittings, see Technical data and type label!
Note! Observe the safety instructions of the lamp manufactur-
er!
Bi-pin lamp (G13)
The lamp is to be inserted to its stop into both holders, (fig.3a) so that
both pins on either side of the lamp engage in the holder. Check the
correct position by slightly pulling the lamp. (fig. 3b)
Note! If the ligth fitting is not connect to main power- more
than 6 month, the battery have to charge 24 h before the light
fitting is started to operation.

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!
– Leave the light fitting switched on for at least 24 hours so that the
battery will be recharged. The green LED in the reflector
is on.
– After that, release a function test of the emergency light connection,
see 7 . Maintenance, function test.
– 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
Mind: There must no insulation measurement be carried out
between L and N, since that would destroy the electronics
(mains input fuse in the VE unit).

Maintenance
Observe the national regulations applicable to the mainte-
nance, servicing and test of apparatus for explosive atmospheres
e.g IEC/EN 60079-17 as well as the general rules of engineering!
8.1
Servicing:
When servicing, in particular those components that affect the
explosion protection, will have to be checked, e. g.:
– Housing and cover pane for any cracks or damages.
– Gaskets for their perfect condition.
– Terminals and blanking plugs for their firm fit.

8.2
– Lamp replacement: Keep replacement intervals as specified by the lamp
manufacturer!
– 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!
8.3
Switch the luminaire off the mains voltage.
The emergency lamp (green marker) must light.
The green LED in the reflector is off
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.
Mind: The full battery capacity will be available after approx. 3
charging/discharging cycles due to physical behaviour.

Prior to replacing or removing any components, observe the
following:
Cut the apparatus off the voltage before opening it or carrying out
repairs!
Repairs that affect the explosion protection (see national standard),
may only be carried out by CCH / EATON or a qualified "electrician"!
Only use certified genuine CCH / EATON spare parts!
(See CCH / EATON spare parts list).
10
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.
