Cable entries, which are not used, must be closed with the
enclosed closure plug (see section 3, Technical Data)! An inlaid dust
protective disc, if existing, must be removed before.
The conductors must not be damaged when skinning resp.
stripping the cable!
When stripping the cable special attention needs to be paid to the
correct length of the conductor end sections (see section 3, Technical
Data)!
Connect the conductors to the right terminals as per marking.
It is important to ensure that the bare conductor is fully inserted
into the terminal and that no cable insulation is clamped!
The dimable light fittings with DALI control unit have two additional
terminals, are marked with "DA".The cables for the DALI control unit have
to be suitable for the main voltage of the light fitting.

Electronic gear in 3-phase-operation

see Fig. 2
The diagram shows the wiring for light fittings or light fitting groups in
3-phase circuits and with a common neutral conductor N
If the common neutral conductor is interrupted and voltage is present,
then light fittings or groups of light fittings may be exposed to unaccept-
ably high voltages and consequently the electronic gear may be de-
stroyed.

8.4 Isolation measurement
see Fig. 3
For measuring the isolating resistance the test voltage must be
put on between the outer conductor and the earth conductor or
between the neutral conductor and the earth conductor only.
After finishing the isolation test the conductor between the mains and the
light fitting must be reconnected safely. Before starting operation the
connection of the neutral conductor must be safe for avoiding any
damage whatsoever of the electronic control gear caused by any
inadmissible excess-voltage in case of an unbalanced mains load.
(see section 8.3)
8.5 Close the light fitting
Any foreign matter shall be removed from the apparatus.
- Join diffuser with included reflector and housing together.
- Hook the clips into the diffuser and fix it.
- After closing the light fitting take care that the whole gasket is
effective.

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!
Before commissioning this explosion-proof lighting fitting please check
and ensure that:
- the light fitting has been installed according to the regulations and in
the allowed operating position.
- the explosion-proof cable glands resp. explosion-proof locking screws
are securely fixed in the housing
(Torques see section 1, Technical Data).
- the pressing screw of every explosion-proof cable gland is tightened
with the required torque (Torques see section 1, Technical Data).
- the connection cable has been firmly installed and is not subject to
any tension whatsoever.
- the bare conductor is fully inserted into the terminal and that no
cable insulation is clamped.
- at versions with connection terminal screws the screws are firmly
tightened (Torque see section 1, Technical Data).
- the light fitting is closed correctly.
- all gaskets are effective.
- the light fitting is not damaged whatsoever.

Maintenance

The national regulations applicable to the maintenance, servicing
and test of apparatus for explosive atmospheres as well as the
general rules of engineering will have to be observed
(IEC/EN 60079-17)!
Especially components which are important for the explosion category
have to be carefully checked. Therefore it must to be checked very
carefully:
- glass, housing and gaskets for any kind of damages.
- the correct installation and tightness of explosion-proof cable glands
and explosion-proof locking screws
(Torques see section 1, Technical Data).
- all parts of plastic inside the light fitting to attend to colour change,
deformation and damaging.
- the tight fit of the conductor and the condition of the cable insulation.
- that the light fitting is closed correctly and the gasket is effective.
