4. Installation
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 light fitting is
permitted in original packaging only!
Pay attention when mounting or repairing the
light fitting, don´t damage the fire-finish of the
glass adquired during moulding (abrasions,
sanding, etc.) that can weaking their
mechanical functions!
Number maximum of light fittings with electronic
ballasts: See table 2
The light fittings are suitable for a wall and for a
ceiling installation.
The light fittings have to be only mounted
horizontally, or with the cable entry from below
for the wall installation.
4.1 Opening and closing the
luminaires
The opening of light fitting always shall be
without voltage!
For opening and closing the light fitting see
secuency fig 3.
The light fitting is well closed when the cover
is completly threaded on the luminaire
enclosure!
Dimensions for mounting: See figure 2

4.3 Mains connection

See wiring diagram.
-Observe the isolation inside the light fittings acc. to
( EN 60598-1, EN 60079-0 / 6.1 remark 3)
-Flexible cables shall be used with trumpet-
shaped cable glands or other suitable entries with
additional pull-relief. (min. protection IP66)
If multi- or fine-wire conneting cables are used,
the wire ends will have to be handled in acc. with
the applicable national and international rules.
(e.g. use of sleeves for strands).
In order to maintain the explosion category, the
conductors will have to be connected with
special care.
The insulation shall reach up to terminal.
The conductor itself must not be damaged.

5. Taking into operation
Prior to operation check the light fitting for its
proper functioning and installation in
compliance with these operating instructions
and others applicable r others applicable regulations! others applicable r others applicable r others applicable r egulations! egulations! egulations! egulations!
Only carry out insulation measurements between
PE and external conductor L1 (L1, L2, L3) as well
as between PE and N.
- measurement voltage: max. 1kV AC/DC
- min. insulation: 2 MΩ
Then the light fitting have to be tightly closed.
Before the first operation, the battery have to be
charged 14 h.
6. Function

6.1 Emergency operation

The duration of the emergency operation is
factory side fixed and can not be adjusted.
The emergency operation will automatically
started when main voltage falls under 75 % for
more than 100 ms or the charging line L L L L L is
switched off (see wiring diagram).
6.1.1 Function test emergency
light
Switch off the mains supply from light fitting.
The 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.
6.2 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.
