6.4 Opening/closing the luminaire
6.4.1 General
The opening of luminaire always shall be without voltage!
All gasket seals must be clean and undamaged before closing the
luminaire.
Make sure the luminaires is well closed before operatrion!
There are Exd thread joints between the heatsink housing and the
glass housing, and between the heatsink housing and top hat.
Glass housing has been fi xed to the heatsink housing by the ma-
nufacturer before delivery screw, and the Exd thread joint has
been tightened by the set scret which is not permitted to be loo-
sen by the user.
6.4.2 Terminal cover
Unscrew the screws and remove the terminal compartment cover.
Carry out the steps in reverse order to close the luminaire.
Check all screws to ensure a secure a secure fi t (Torque for screws:
1.5Nm). See Fig. 4
6.5 Electrical connection
The electrical connection of the lighting must only be established
by qualifi ed electricians. Make sure the supply voltage is the same
as the luminaire voltage!
Use proper supply wiring as specifi ed on the nameplate of the
luminaire and in this instruccions!
Excessive tightening may affect or damage the connection.
See section 6.4 for notes on opening and closing the lamp.
Connect cable according to the terminal numbering and circuit diagram.
The conductors shall be connected with special care in order to main-
tain the explosion category.
Leads connected to the terminals shall be insulated for the appropriate
voltage and this insulation shall extend to within 1mm of the metal of
the terminal throat.
When more than one single or multiple standed wires connecting to
terminal block, or multiple conductors join together, a single insulated
crimpled boot lace ferrule must be used.
The conductor itself shall not be damaged.
The connectible min. and max. conductor crosssections shall be obser-
ved (see technical data). All terminal screws, used and unused, shall be
tightened down to between 1.2~2Nm.
Main connection: See wiring diagram. Fig. 4 and Fig. 5.
6.6 Putting into operation
Prior to putting the apparatus into operation, the tests specifi ed in the
relevant national regulations shall be carried out.
Insulation measurements may only be carried out between PE and the
external conductor L1 (L2, L3) as well as between PE and N.
-Measurement voltage: Max. 1kV AC/DC
-Measurement current: Max. 10 mA
-The luminaire may only be operated when closed.
7 Maintenance / Servicing
The valid national regulations for the maintenance/servicing of
electrical equipments for use in potentially explosive atmosphe-
res 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 20 minutes after switching off.
Potential electrostatic hazard clean only with a damp cloth.
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
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 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 se-
curely.
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 neces-
sary, seccion 8 of these operating instructions shall be followed.
8 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 dis-
mantling of individual parts.
Only use original spare parts. Repairs that affect the explosion pro-
tection 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 instructions indicated in IEC/EN 60079-19.
Reparation of the sealed part between collar and glass shall be done by
EATON Crouse-Hinds Division only user care not authorized to repair
any sealed part of the luminaire.
Modifi cations to the equipments or changes of its design are not per-
mitted.
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, replace-
ment of these components is mandatory. In case of doubt, the res-
pective 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.
9 Disposal / Recycling
When the equipment or their parts is disposed of, the respective valid
national regulations on waste disposal shall be observed. In order to
facilitate the recycling of individual components, plastic parts are
Subject to alteration or supplement of this product without any adver-
tisement before.
Save these instructions for future reference.
