Only luminaires with protection modes "d e marked on the label can be
opened when an explosive atmosphere is present.
Once the luminaire is opened, the batteries or their parts shall not be
manipulated when an explosive atmosphere is present, this operation can
only be done when there is no explosive atmosphere present.
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 type approved for each light fitting is specified in point 3 and in
the label of the luminaries. Replace the lamps according with the
manufacturer recommendation.
For installation of lamps, 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 lamp into the corresponding lamp holder, test
for a secure installation, insert the tray again, see Fig. 3 item 5, connect the
cable it 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 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 indi-
vidual 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 conduc-
tor L1 (L2, L3) as well as between PE and N.
- Measurement voltage:Max. 1KV AC/DC
- Min Insulation 2MΩ
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.
Before put into operation the batteries shall be charged during 14hs
minimum.
7. Operation
7. 1
This luminaire operates in non-maintained mode, the main lamp is off
when main AC voltage is present, this situation is indicated by a white LED
on.
When the supply voltage falls below 75% of its nominal value by more than
100ms the fixture goes into emergency mode and the emergency lamp is
turned on.
The proper functioning of AC circuit lamp is indicated by a green LED on,
while the Red LED off indicates a fault in the battery charger circuit.
If any of these LED's will turn off, open the luminaire as showed in 6.2 and
6.2.1 to control the correct state of the fuses.
7. 2 Function test of the emergency light
Switch off the main supply AC voltage from the light fitting the emergency
lamp will operate.
The test function should not exceed 90 min.
If the emergency lamp is turned off within the test period thought the battery
is fully charged, the latter will have to be replace by a new battery set.

7. 3 Battery charge

At temperatures below -5 °C and above +35 °C the battery is not fully charged
for electrochemical reasons.
Note: New batteries will reach their total useful capacity only after 3 charging
/ discharging cycles.

8 Maintenance / Servicing

The valid national regulations for the maintenance/servicing of
electrical equipments for use in potentially explosive atmospheres shall
be observed (i.e. EN/IEC 60079-17).
Before opening the enclosure, it is necessary to ensure that the voltage
supply has been isolated and should allowed to cool down for 10
minutes after switching off.
The necessary intervals between servicing depend upon the specific
application and shall be stipulated by the operator according to the respec-
tive operating conditions. We recommend a regular maintenance according
to an approved preventive maintenance program.
During servicing, above all, parts on which the explosion protection depends
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
damaged.
- 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 efficiency and intactness. Replace older or
damaged seals with new seals.
- Be aware about the lamp tube change intervals specified by the
manufacturer of it, lamp tubes types must be as specified.
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 fit securely.
All electrical and electronic material inside of the enclosure shall be
maintained 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.
