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.
- the light fitting is closed correctly.
- all gaskets are effective.
- the light fitting is not damaged whatsoever.

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.
10.1 Cleaning the light fitting
At the plastic parts of the light fitting there is a danger of ignition
due to electrostatic charging! For cleaning the housing and cover
outside and inside and for cleaning internal plastic components use
only cold or lukewarm water (if necessary with a mild cleaning
agent) together with a viscose sponge or a soft fibrous-free cloth!
Pay attention to the following in case of application of this light
fitting in dusty atmospheres:
Dust deposits have got thermal insulation characteristic features. It is
necessary to clean the fitting from dust regularly. In case the dust layer
may be higher than 5 mm it must be ensured that the surface tempera-
ture of the light fitting does not exceed the maximum permissible surface
temperature of the specific dust considering the thickness of the dust
layer. The dust layer must not exceed 50 mm at any time.

Repairs and overhaul may only be carried out with genuine
EATON/COOPER CROUSE-HINDS spare parts.
Repairs that affect the explosion protection, may only be carried
out by EATON/COOPER CROUSE-HINDS or a qualified electrician in
compliance with the applicable national rules (IEC/EN 60079-19).
In the event of damage, replacement of these components is
mandatory. In case of doubt, the respective apparatus shall be sent
to EATON/COOPER CROUSE-HINDS for repair.
- For applications in dusty atmospheres the light fitting must be
cleaned before opening!
- Ensure that there will be no dust getting into the light fitting while it
is open!
- Replace damaged explosion-proof parts by original spare parts from
the EATON/COOPER CROUSE-HINDS only!
11.1 Replacing LED and electronic gear
Replacement of the LED boards and/or of the electronic gear has been
described in the separate instructions which can be found attached to the
spare parts to be supplied.
12
When the apparatus is disposed of, the respective national regulations on
waste disposal will have to be observed.
Subject to modifications or supplement of the product range.
In order to facilitate the recycling of individual components, plastic parts
are provided with the identification mark of the plastic material used.
