Opening The Device / Electrical Connection; Putting Into Operation - Eaton CROUSE-HINDS Série Instructions D'utilisation

6. Installation
The IEC/EN 60079-14, relevant national regulations and the generally re-
cognized rules of engineering shall be applied for the installation and ope-
ration.
Transport and storage of the luminaries is permitted in the original packa-
ging and specifi ed positions only.
Pay attention when installing, maintaining or repairing the light fi t-
tings, do not damage the fi re-fi nish of the glass surface by abra-
sions, 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 lumi-
naries should be switched off during daytime by a photocell control.
The maximum number of luminaries with electronic ballast connected to the
same circuit as indicated in the table 2 should be observed
The improper installation and operation of light fi ttings 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
EATON catalogue for the correct selection of the mounting accessories.
The light fi tting may only lie fl at on and be fi xed torsion-free to the fastening
points provided for direct assembly. The screws chosen shall fi t the fi xing
hole and shall not damage the hole (e.g. use of a washer, select the correct
length, etc.). The number of screws used for fi xing the equipment shall
correspond to the number of fi xing holes in the light fi tting.
Special attention shall be paid to the PE connections.
Warning: Over tightening might damage the light fi tting.

6.2 Opening the device / Electrical connection

Before opening the light fi tting, it is necessary to ensure that there is
no voltage and it must be allowed to cool down for 10 minutes after
switching off, as a safety measure.
The connection of explosion-protected light fi ttings may only be carried out
by specialists. These luminaries shall be connected directly in the fl ame-
proof enclosure using certifi ed fl ameproof cable entries, whereby the moun-
ting 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 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.
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. 1KV AC/DC
- Measurement current: Max. 10 mA
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.
