Putting Into Operation; Maintenance / Servicing - Eaton CROUSE-HINDS Serie Instrucciones De Uso

6.2.1 Lamp
The lamp type approved for each light fi tting is specifi ed in table 1,2 and in
the label of the luminaries.
For installation of lamp remove the screws of the glass-frame, (see Fig 5),
and open the enclosure. When uncrewing the screws from the lamp com-
partiment cover, we recommend to let in a couple of screws on the frame
glass cover to facilite the closing procedure.
Install or replace the suitable lamps into the corresponding lamp holders,
test for a secure installation, and then close the glass-frame 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.
6.3 Ex cable entries / Ex blanking plugs
Only suitable certifi ed Ex cable entries and 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 cer-
tifi 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. Torque of 15Nm for the original
plug suppied 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 certi-
fi ed blanking plug.
6.4 Closing equipments / Cover lock
Any foreign matter shall be removed from the equipment.
Grease the fl ange joints, 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.
Close the enclosure and tighten the screws. The luminaire is well clo-
sed when the gap of the fl ange joints, in every side of the enclosure are
<0,15mm. Torque of bolts 17,7 Nm.

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.

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 and fl ange joints, like covers and cable
entries, shall be properly greased, in good conditions, clean and
without any corrosion or damaged.
- The thread and fl ange joints shall not be treated, painted nor
varnished!, only shall be greased.
- Check all seals for effi ciency and intactness.
damaged seals with new seals.
- Be aware about the lamp change intervals specifi ed by the
manufacturer of it, lamp types must be as specifi ed.
The fl ameproof of these apparatus have to be greassed permanentlly in
order to ensure it protection in front of the corrosion, water ingrees and
seize-up problems. Cleaning rest of grease and corrosion, not use sharp
metallic devices that can damage the surface of the joint, and grease it
using apropiate grease thermically and chemically stable with a drop point
> 200ºC like e.g.: Molikote® BR2 plus.
When the housing need to be repainted, pay attention that the fl ameproof
joints rest without any part with coating. Less for the PTFE coating, that in
this case ask EATON for the correct process.
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
Repairs and overhaul may only be carried out with genuine EATON spare
parts.
Switch off the equipment before opening or isolate it before the dismantling
of individual parts.
Only use original spare parts. Repairs that affect the explosion protection
may only be carried out by EATON or a qualifi ed electrician in complian-
ce with the applicable national rules. For repair electrical equipments in
protection mode is suggested follow the instructions indicated in IEC/EN
60079-19.
Modifi cations to the equipments or changes of its design are not permitted.
Glass-metal seal and/or fl ameproof joints can only be repaired by
EATON, user is not authorized to replace the glass-metal seal, or repair
fl ameproof joints.
If necessary to change the original screws of closing enclosure EJ (body
to cover), pay special attention to use screws of the same characteristics,
A2-70, and dimensions identical to those originally supplied.
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 respective
equipments shall be sent to EATON for repair. Reconstruction or mo-
difi cations to equipments are only possible within the scope of the
approvals and shall be certifi ed afterwards.
9 Disposal / Recycling
When the equipment or their parts is disposed of, the respective valid na-
tional regulations on waste disposal shall be observed. In order to facilitate
the recycling of individual components, plastic parts are provided with the
identifi cation mark of the plastic material used.
