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

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 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 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

- 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 dama-
ged 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.
