6.2.1 Lamp
The lamp type approved for each light fi tting is specifi ed in point 3 and in
the label of the luminaries. Replace the lamps according with the manu-
facturer 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 con-
nection between tray and body of the light fi tting.
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 fi tting, screw the 2 nuts, item 4, and then close the light fi tting as
indicated in point 6.4.
Only lamps 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.
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 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
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 supplied with the light fi tting.
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 cer-
tifi 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 grea-
se 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 anticloc-
kwise). The cover can then be screwed into the enclosure base by tur-
ning 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
individual 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 con-
ductor L1 (L2, L3) as well as between PE and N.
- Measurement voltage:
- Min Insulation:
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.
Before put into operation the batteries shall be charged during 14hs mi-
nimum.
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 fi xture 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 fi tting 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 char-
ging / discharging cycles.
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.
Max. 1KV AC/DC

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. IEC/EN 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 specifi c
application and shall be stipulated by the operator according to the res-
pective operating conditions. We recommend a regular maintenance ac-
cording to an approved preventive 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 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 effi ciency and intactness. Replace older or
damaged seals with new seals.
- Be aware about the lamp tube change intervals specifi ed by the
manufacturer 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.
9 Repair / Overhaul / Modifi cations
Repairs and overhaul may only be carried out with genuine EATON
Crouse-Hinds Series spare parts.
Switch off the equipment before opening or isolate it before the dismant-
ling of individual parts.
Only use original spare parts. Repairs that affect the explosion protection
may only be carried out by EATON Crouse-Hinds Division or a qualifi ed
electrician in compliance with the applicable national rules. For repair
electrical equipments in protection mode is suggested follow the instruc-
tions indicated in IEC/EN 60079-19.
Modifi cations to the equipments or changes of its design are not permitted.
All reparations have to be done without voltage!
In the event of damage to the fl ameproof enclosures or other part of
equipments that could affect the mode of protection, replacement
of these components is mandatory. In case of doubt, the respecti-
ve equipments shall be sent to EATON Crouse-Hinds Division for
repair. Reconstruction or modifi cations to equipments are only
possible within the scope of the approvals and shall be certifi ed
afterwards.
If it is expressly stated on the label of the luminaire, do not open it
when an explosive atmosphere is present.
Only luminaires with protection modes "d e marked on the label can be
opened when an explosive atmosphere is present.
The batteries or their parts never shall be manipulated when an explosive
atmosphere is present.
9.1 Battery change
Only change batteries outside the hazardous area for explosive atmos-
pheres.
Use only original spare battery set from EATON Crouse-Hinds Series.
- Open the light fi tting as shown in point 6.2
- Remove the internal tray according to section 6.2.1
- Disconnect the plug terminal
- Cut the fasteners that hold the battery pack.
- Install the new battery pack and secure it with the fasteners
