Putting Into Operation - Cooper Crouse-Hinds CEAG AB 12 108 EVG Serie Instrucciones De Uso

6. Installation
The EN 60079-14, relevant national regulations and the generally
recognized rules of engineering shall be applied for the installation and
operation.
Transport and storage of the luminaries is permitted in the original
packaging and specified positions only.
Pay attention when installing, maintaining or repairing the light
fittings, do not damage the fire-finish of the glass surface by
abrasions, sanding, small strokes, etc. that can weaken their
mechanical functions.
Intensive sun radiation in areas of high ambient temperatures may
cause inadmissible temperature rise inside of the luminaries. This
may result a decrease in lifetime of the electronic ballast (EVG) or
electronic components inside of the luminaries. Therefore those
luminaries should be switched off during daytime by a photocell
control.
Earth leakage protection, the earth leakage current of the luminaries
AB12 is normally less than 1 mA, due to this it is suggested non install
more than 30 luminaries for earth leakage switch with sensibility of
30mA.
The improper installation and operation of light fittings can result
in the invalidation of the guarantee.
6.1 Mounting
Fixing dimensions are shown in Figure 2 (B).
Luminaries are suitable for ceiling, wall or pole mounting, the accessories
are not included, see COOPER Crouse-Hinds catalogue for the correct
selection of the mounting accessories and self-adhesive pictograms.
The light fitting may only lie flat on and be fixed torsion-free to the fastening
points provided for direct assembly. The screws chosen shall fit the fixing
hole and shall not damage the hole (e.g. use of a washer, select the
correct length, etc.). The number of screws used for fixing the equipment
shall correspond to the number of fixing holes in the light fitting.
Special attention shall be paid to the PE connections.
Warning: Over tightening might damage the light fitting.
6.2 Opening the device / Electrical connection
Before opening the light fitting, it is necessary to ensure that there
is no voltage and it must be allowed to cool down for 10 minutes
after switching off.
The connection of explosion-protected light fittings may only be carried
out by specialists. These luminaries shall be connected directly in the
flameproof enclosure using certified flameproof cable entries, whereby
the mounting instructions for the cable entry shall be taken into account
(see Section 6.3 Cable Entries).
Warning: In order to establish the type of protection "Ex-d flameproof ",
it is essential to pay attention to the correct mounting of the cable
and cable entry.
To open a flameproof enclosure (see Fig. 3), the interlocking screw, item
1, in the cover has to be unscrewed. The cover, item 2, can then be
removed from the luminary by turning it anticlockwise.
Warning: The cover shall be safeguarded against falling off.
To maintain the explosion protection, conductors shall be connected with
special care.
The insulation shall reach up to the terminal. The conductor itself shall
not be damaged.
The minimum and maximum conductor cross sections that can be
connected shall be observed, see point 3 technical data. All screws and/
or nuts of connection terminals, including those not in uses, shall be
tightened down securely.
Excessive tightening can affect the connection.
6.2.1Lamp
The lamp tube type approved for each light fitting is specified in table 1
and in the label of the luminaries.
For installation of lamps tubes, once performed the steps mentioned in
point 6.2 (see Fig 3), remove the 2 nuts item 4 and extract the tray, item 5.
Take special care to remove correctly the cable for internal PE
connection between tray and body of the light fitting.
Install or replace the suitable lamps into the corresponding lamp holders,
test for a secure installation, insert the tray again, see Fig. 3 item 5,
connect the cable for internal PE connection between tray and body of
the light fitting, screw the 2 nuts, item 4, and then close the light fitting as
indicated in point 6.4.
Only lamps tubes that are approved for each type of light fitting may be
used. If you have any doubt, please consult with COOPER Crouse-Hinds.
6.3 Ex-d cable entries / Ex-d blanking plugs
Only suitable certified flameproof cable entries and certified
flameproof blanking plugs may be used. These should be for the
same groups of explosion of the light fittings, in this case IIC for
gas and IIIC for dust.
The relevant mounting and installing manufacturer directives for certified
cables entries and blanking plugs shall be observed.
When using cable entries with a degree of protection that is lower than
the IP protection of the light fitting (see Technical Data), the degree of
protection IP for the complete unit is reduced.
In order to ensure the required minimum degree of protection, the cable
entries shall be tightened down securely. Torque of 15Nm for the original
plug suppied with the light fitting.
Over tightening can impair the degree of protection.
In order to guarantee and/or establish the explosion protection and
degree of protection, unused entry holes shall be sealed with a
certified flameproof blanking plug.
6.4 Closing equipments / Cover lock
Any foreign matter shall be removed from the equipment.
Grease the cover thread before screwing the cover, preferably with grease
thermally and chemically stable i.e.: Molikote® BR2 plus.
Pay attention to the correct fit of the seal into the cover. All seals must be
clean an undamaged
To close the light fitting, see fig. 3 item 2, it is necessary to fit the cover
onto the light fitting body correctly (if necessary, turn the cover
anticlockwise). The cover can then be screwed into the enclosure base
by turning it in a clockwise direction until the stop is reached. After this,
the cover shall be fixed in position with the interlocking screw of the
cover, see Fig. 3 item 1.

6.5 Putting into operation

Before putting the light fitting into operation, the tests specified in the
individual national regulations shall be performed. In addition to this, the
correct functioning of the light fitting shall be checked in accordance with
these operating instructions and other applicable regulations.
Only carry out insulation measurement between PE and external con-
ductor L1 (L2, L3) as well as between PE and N.
- Measurement voltage:Max. 1KV AC/DC
- Measurement current: Max. 10 mA
The light fitting may only be operated when closed
Warning: Only certified equipments may be put into operation.
Improper installation and operation of the lamp leads to loose of the
guarantee
