Putting Into Operation; Maintenance / Servicing - Eaton CROUSE-HINDS AB 12 Série Instructions D'utilisation

Warning: In order to establish the type of protection "Ex-d fl ameproof ",
it is essential to pay
attention to the correct mounting of the cable and cable entry.
To open a fl ameproof 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 connec-
ted 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, (torque = 0,7Nm)
Excessive tightening can affect the connection.
6.2.1 Lamp
The lamp tube type approved for each light fi tting is specifi ed 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 fi tting.
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
fi tting, screw the 2 nuts, item 4, and then close the light fi tting as indicated
in point 6.4.
Only lamps tubes that are approved for each type of light fi tting may be
used. If you have any doubt, please consult with EATON Crouse-Hinds
Division.
Due you can use LED tubes from many manufacturers, observe the correct
selection of LED tubes according to the light fi ttings LED type, these must
be suitable for direct mains connection without any driver, ballast or control
gear, T8 for G13 lamp socket and with appropriate length.
Special care to control the correct LED tubes selection according to the lu-
minaire wiring type shall be taken. Wiring type is showed in the internal tray
of the luminaire and in the Fig. 1 for the types LED, LED 1E and LED 1EF
for luminaire LED 1EF, the "F" fuse supplied by the LED tube manufactures
shall be installed.
Warning: Do not install any type of fl uorescent lamps in any LED type
light fi ttings.
Due to these LED type of light fi ttings have direct mains connection
and have no control gear inside, the use of fl uorescent tubes in these
LED type of light fi ttings can cause an internal short circuit or an ex-
plosion that can destroy the light fi tting.
The improper use of LED type luminaires and the use of LED tubes
not suitable for the provided wiring may result in an invalidation of
the guarantee.
6.3 Ex-d cable entries / Ex-d blanking plugs
Only suitable certifi ed fl ameproof cable entries and certifi ed fl ame-
proof blanking plugs may be used. These should be for the same
groups of explosion of the light fi ttings, in this case IIC or IIB (see
table in Fig. 2) for gas and IIIC for dust.
The relevant mounting and installing manufacturer directives for certifi ed
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 fi tting (see Technical Data), the degree of protec-
tion 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.
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 certi-
fi ed fl ameproof 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 fi t of the seal into the cover. All seals must be
clean an undamaged.
To close the light fi tting, see fi g. 3 item 2, it is necessary to fi t the cover onto
the light fi tting 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
fi xed in position with the interlocking screw of the cover, see Fig. 3 item 1.

6.5 Putting into operation

Before putting the light fi tting into operation, the tests specifi ed in the indivi-
dual national regulations shall be performed. In addition to this, the correct
functioning of the light fi tting shall be checked in accordance with these
operating instructions and other applicable regulations.
Only carry out insulation measurement between PE and external conductor
L1 (L2, L3) as well as between PE and N.
- Measurement voltage: Max.:
- Min isulation:
The light fi tting may only be operated when closed
Warning: Only certifi ed equipments may be put into operation.
Improper installation and operation of the lamp leads to loose of the gua-
rantee.
Warning
To avoid the risk of fi re, explosion, or electric shock, this product should
be installed, inspected, and maintained by a qualifi ed electrician only,
in accordance with all applicable electrical codes.

7 Maintenance / Servicing

The valid national regulations for the maintenance/servicing of electri-
cal equipments for use in potentially explosive atmospheres shall be
observed (i.e. IEC/EN 60079-17).
Before opening the enclosure, it is necessary to ensure that the volta-
ge supply has been isolated and should allowed to cool down for 10
minutes after switching off.
The necessary intervals between servicing depend upon the specifi c appli-
cation and shall be stipulated by the operator according to the respective
operating conditions.
We recommend a regular maintenance according to an approved preventi-
ve maintenance program.
During servicing, above all, parts on which the explosion protection de-
pends shall be tested or visually inspected to ensure their correct state, i.e.:
- Enclosure threaded parts like cover and cable entries, shall be properly
greased, in good conditions, clean and without any corrosion or dama-
ged.
- The thread shall not be treated, painted nor varnished!, preferably
with grease thermally and chemically stable i.e.: Molikote® BR2 plus.
- Check all seals for effi ciency and intactness. Replace older or damaged
seals with new seals.
- Be aware about the lamp tube change intervals specifi ed by the manu-
facturer of it, lamp tubes types must be as specifi ed.
Any damaged parts shall be replaced immediately using original parts or
damaged parts shall be repaired by the manufacturer.
Check that connection terminals, cable entries and blind plugs fi t securely.
All electrical and electronic material inside of the enclosure shall be main-
tained as per their own instructions.
If, in the course of servicing, it is ascertained, that repairs are necessary,
section 8 of these operating instructions shall be observed.
8 Repair / Overhaul / Modifi cations
