Inserting the lamp

Mind: Take the double-ended tubular lamp
insert with a dry cloth only. When fitting in
the lamp insert, it shall be pushed into the
holder until you feel that the socket parts
lock in.
In case the rated voltages deviate > 5%, the
indications of the lamp manufacturer will
have to be observed.
The illuminants are not included in our
standard delivery.
For inserting the lamp into the lampholder of
the dTLS 85 land dHLS uminaire, proceed as
follows:
12
Explosion protected light fittings
Type: dHLS 85 and dTLS 85
The bezel ring is screwed out of the luminaire
housing. To do so, first the hexagon bolt M5 in
the bezel ring will have to be unscrewed. Now
the lampholder is accessible and the lamp can
be inserted into the luminaire (see fig. 4).
As a standard, the luminaire dTLS is delivered
for the use with metal vapour high-pressure
lamps. The distance of the lampholder support
for these is 149 mm (see fig. 5).
Should sodium vapour lamps be used, the
distance between the lampholder supports will
have to be adjusted to 193 mm (the respective
tapped holes have been provided, see fig. 5).
Does not apply for dTLS 85070.
If the dTLS light fitting is fitted with a „diffuser
with reflector" group, this assembly can be
detached by first removing the circlip for locking
(see fig. 6).
After having inserted the lamp, the luminaires
are closed in inverse order by screwing in the
bezel ring.
Pay attention that on the closed light fitting the
hexagon bolt is located between two marking
ribs (see fig. 6).
6.5 Closing the light fitting
When putting the bezel ring in place take
care that the cover thread is properly
screwed into the luminaire housing.
Any foreign matter shall be removed from
the apparatus.
In order to ensure the required minimum
protection category, the bezel ring shall be fully
screwed home in the luminaire housing and be
secured with the locking screw.
As well the cover screws are to be tightened
down.

Taking into operation

Prior to taking the apparatus into operation,
the tests specified in the relevant national
regulations will have to be carried out. Apart
from that, the correct functioning and installa-
tion of the apparatus in accordance with these
operating instructions and other applicable
regulations will have to be checked.
Incorrect installation and use of the
luminaires can invalidate the guarantee.
Luminaires with compensation box only to
be switched on at ambient temperatures
over -20 °C.
7 Instandhaltung / Wartung
The relevant national regulations which
apply to the maintenance/repair of electrical
apparatus in explosive atmospheres, will
have to be observed (IEC/EN 60079-17).
Before opening the enclosure make sure
that the apparatus is disconnected from the
voltage, or take the appropriate protective
measures.
Mind: After having switched off the light
fitting, wait at least 10 minutes before
opening it!
The required maintenance intervals depend on
the respective application and will therefore
have to be determined by the user dependent
on the conditions of use.
When servicing the light fittings, particularly
those parts that are decisive for the type of
protection against explosion, will have to be
checked (e. g. intactness of flameproof
enclosed components, enclosure, cable entries,
efficacy of the cover gaskets).
If during servicing repairs prove to be neces-
sary, section 8 of these operating instructions
will have to be observed.
Compensation:
Mind! The condition of the adhesive tape on
the breather opening of the capacitor is to
be checked at regular intervals.
If the adhesive tape is damaged then the
capacitor shall be changed out.

Repairs / Modification

Repairs may only be carried out with
genuine CCH / EATON spare parts.
In case of a damaged flameproof enclosure,
only its replacement is permitted. In case of
doubt, the respective apparatus will have to
be returned for repair to CCH / EATON.
Repairs that affect the explosion protection,
may only be carried out by CCH / EATON or
a qualified electrician in compliance with the
applicable national rules (IEC/EN 60079-19).
Peripheral surfaces of the air gaps on
the flameproof enclosure must not be
subsequently worked or painted.
Modifications to the apparatus or changes of
its design are not permitted, except for the
mounting of additional CCH / EATON accessories.
9

Disposal / Recycling

When the apparatus is disposed of, the
respective national regulations on waste
disposal will have to be observed.
In case of disposal you can obtain additional
information from your Cooper Crouse-Hinds /
EATON branch.
Subject to modifications or supplement of the
product range.
