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

To open the luminaire (see Fig. 1), the interlocking screw, item 2, in the co-
ver and item 1 in the glass collar has to be unscrewed. The cover or glass
collar, can then be removed from the luminary by turning it
anticlockwise.
Warning: The cover or glasscollar shall be safeguarded against falling
off.
To maintain the explosion protection, conductors shall be connected with
special care, connect main cable to terminals L,N and PE. (See Fig.4)
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 2,5Nm.
Excessive tightening can affect the connection.
6.2.1 Lamp
The lamp type approved for each light fi tting is specifi ed in table 1. and in
the label of the luminaries.
For installation of lamps unscrew the interlocking screw (1) of the glass
collar, then remove it from the luminaire by turning it anticlockwise.
Install or replace the suitable lamps into the corresponding lamp holders,
test for secure installation, 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 Cable entries / blanking plugs
Only suitable Ex certifi ed cable entries and blanking plugs may be
used. These should be for the same group of explosion of the light fi t-
tings, in this case IIC for gas and IIIC for dust and shall have the same
mode of protectection than the conexion enclosure.
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.
In case of use the original suppled blanking plugs the torke small be 15Nm
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 cover and glass collar thread before screwing the cover and
glasscollar, preferably with grease thermally and chemically stable i.e.: Mo-
likote® BR2 plus.
Pay attention to the correct fi t of the seals cover and glass collar. All seals
must be clean an undamaged.
To close the light fi tting, see fi g. 1, it is necessary to fi t the cover and glass
collar onto the light fi tting correctly (if necessary, turn the cover and glass
collar anticlockwise). The cover and glass collar can then be screwed into
the enclosure by turning it in a clockwise direction until the stop is reached.
After this, the cover and glass collar shall be fi xed in position with the inter-
locking screw, see Fig. 1 item 1 and item 2.

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
L as well as between PE and N.
- Measurement voltage: Max. 1KV AC/DC
- Minimun isolation: 2M
Subject to alteration or supplement of this product without any advertise-
ment before.
Save these instructions for future reference.
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.
Verify that installed lamp, particularly LED lamps allow this type of measure,
otherwise remove the lamp before performing this test.
The luminaire can only be used when it is properly closed, luminaire is con-
sidered properly closed when the collar glass and cover, if it exist, are fully
threaded to the body and locking screws are tightened.
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.

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.
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.
