Lumiglas Luminaire USL 07 LED-Ex, 3541.281.00, 3541.282.00, 3541.284.00, 3541.283.00 Operating Instructions Manual

• Description:

The luminaire USL 07 LED-Ex is designed with ignition pro­ tection type – flameproof enclosure “d” for the housing and
with ignition protection type increased safety “e” for the
terminal compartment as well as protection by enclosure “t”.
It is approved for applications in potentially explosive areas –
Ex zones 1 and 2 and also zones 21 and 22.
Lumistar luminaires are intended for observing processes
in reactors, apparatuses, vessels, etc. Under no circumstances
should a luminaire be utilised as a substitute for the mating
flange or the complete sight glass flange fitting or used on
its own to close a vessel port.
Lumistar luminaires intended for use in potentially ex­ plosive environments must always be installed, connected
and serviced by persons who have been trained expressly for
this purpose and are authorised to do this work.
Caution: Avoid looking into the light source – risk of damage
to the eyes!

• Mechanical installation:

The Lumistar USL 07 LED-Ex luminaire fits the following
nominal sizes with the corresponding attachment:

• Attachment with luminaire mounting:

The luminaire is attached to the mating flange of a circular
sight glass unit or flow indicator or to the slotted cover nut
of screw-type sight glass fittings to DIN 11851 using the
mounting parts – straight or angular bracket.
Straight bracket for DN 50 to 100
Angular bracket for DN 125 to 200

• Mounting with flange adapter:

The flange adapter can be welded to the slotted nut
(DIN 11851 or similar) or underlaid with the corresponding
size.

Please order any required mounting parts separately.

• Electrical connection:

- Open the cover of the terminal compartment

- Insert cable through the Ex eb/Ex tb cable entry gland (5)
into the terminal compartment

- Wire cable to Ex terminals (6)
Rated cross-section = 2.5 mm² (single, fine and stranded
wired)

- Then replace the cover of the terminal compartment com­ plete with seal and screw the cover back on again

- The external protective conductor terminal (1) needs to be
connected to a separate plant earthing point

- The luminaire is internally fused with a 1 A or 1.6 A micro­ fuse on the power supply card. All appropriate and approved
Ex eb/Ex tb cable glands can be used, provided they have a
temperature resistance of at least 80°C (e.g. cable gland
M20x1.5, part no.: 9103.141.00)

- The connecting cable should be secured after a maximum
distance of 1 metre

- Caution: Excess voltage or under-voltage may cause a
luminaire failure!

- When using 24 V mains power supply, the parallel connec­ tion of luminaires with only one feed line should be avoided.
The resulting major impedances in the feed line due to the
reduced line cross-section together with contact resistances
caused by terminals and connectors can lead to malfunctions
in the luminaire.

• Maintenance:

- Please use original replacement parts only

- Accessories need to be ordered separately

- The luminaire should be kept clean. To ensure optimum
light emission, the glass lens should be cleaned at regular
intervals

- After opening the luminaire, the thread of the screwed lens
should be regreased (e.g. with AEMA-SOL 6 B made by
A.E. Matthes)
