Installation
For the mounting and operation, the respective
national regulations as well as the general rules
of engineering will have to be observed
(IEC/EN 60079-14).
6.1
Mounting
The luminaires can be suspended from carrying
ropes by means of eyebolts DIN 580 (see fig. 1).
10 pcs. carrying ropes are optionally available as
accessories, with order No. GHG 690 1921 R0003.
HME
On the top of the luminaire there are two M10
drilled holes by means of which it can be screwed
onto brackets or scaffold profiles (see fig. 1).
Should mounting brackets be used,
HSE, HST,
type L218 order No. GHG690 1913 R0001,
HIT
type L430 order No. GHG690 1913 R0002,
are available as accessories (see dimensional
drawings page 6 and 7), these have to be
screwed into the M10 holes which are laterally
arranged on the luminaire housings.
The fastening screws shall match the fastening
holes (see dimensional drawings page 6 and 7).
They must not damage the hole (e.g. use of a
washer) and shall be tightened down.
If the screws are overtightened, the
apparatus can be damaged.
6.2
Opening the device/
Electrical connection
Before opening the apparatus, ensure that it
has been isolated from the voltage supply,
or take appropriate protective meassures.
The electrical connection of the luminaire
may only be carried out by skilled staff.
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
In order to maintain the explosion category,
the conductors will have to be connected with
special care.
If multi- or fine-wire connecting cables are
used, the wire ends will have to be handled in
acc. with the applicable national and interna-
tional rules (e. g. use of ferrules).
The insulation of the conductors shall reach
up to the terminal. The conductor itself shall
not be damaged.
The connectible min. and max. conductor
cross-sections will have to be observed.
The supply terminals are designed for the
connection of copper conductors.
Between connecting wires keep an distance of
>5 mm at 250 V (acc. IEC/EN 60079-7).
All screws and/or nuts of the supply terminals,
also of those remaining vacant, shall be
tightened down.
Excessive tightening may affect or damage
the connection.
The electric connecting lead is introduced
through the KLE cable entry and connected to
the terminals L / N / PE (see fig. 1 and 2).
The conductor cross-section is max. 4 mm².
The PE connection is specially marked in the
terminal compartment. Only a single-phase
through-wiring is possible.
The mains connection of p.f. corrected
luminaires is established in the compensating
capacitor box.
Mind:
The dTLS 85 luminaire shall be mounted so
that the position of the lamp insert in the
luminaire is at max. +/- 45° (see fig 3).
6.3
Cable entries (KLE);
blanking plugs
Generally, only certified cable entries and
blanking plugs may be used. Flexible cables
shall be used with trumpet-shaped cable
glands or other suitable entries with
additional pull-relief.
When using cable entries with a lower IP
protection than that which applies to the
luminaire (see page 3), the IP protection of the
whole device will be reduced.
The mounting directives applicable to the cable
entries fitted shall be observed.
In order to establish the minimum protection
category, unused holes shall be closed with a
certified blanking plug.
Care has to be taken that when fitting the cable
entries, sealing inserts appropriate to the cable
diameter be used. In case of sealing inserts that
are cut out, it will have to be ensured that the
insert is properly adapted to the cable diameter.
In order to ensure the required minimum
protection category, the cable entries will have
to be tightened down.
Overtightening might impair the protection
category.
All vacant metric CCH / EATON cable entries
shall be closed with the certified blanking plug
for metric cable entries.
