• Important, please note:
Sight glass luminaires are specifically designed and solely
intended for mounting with or onto flanged sight glass
fittings. Under no circumstances should sight glass
luminaires be used as a substitute for the cover flange or
the complete sight/light port or as a lid or cover for vessel
openings. Luminaires for use in potentially explosive
environments must be mounted, installed and serviced by
staff who have the relevant qualifications and have been
properly trained for this type of work. Please observe the
data set out in the EC type-examination certificate!
• General operating conditions:
- Independent of pressure/vacuum in the vessel
- Approved for use in Ex environments:
Gas: Zones 1 and 2; Dust: Zones 21 and 22
- Approved for use in ambient temperatures of between
-20°C and +60°C or +40°C, depending on the lamp power
(see type plate and temperature classification parameters).
• Electrical data, general:
- Voltage, power, temperature class and protection rating
are shown on the type plate.

- The variant with integrated transformer is PTC-protected
with 5 W; thermal link with 10 W.
No fuse replacement necessary.
- Power supply: AC or DC, depending on lamp fitted
- Caution: Only alternating current should be used on
luminaires with integrated transformer.
- Warning: Over-voltage will cause premature lamp failure!

• Parameters/Temperature classification:
• Mounting with hinged bracket:
The hinged bracket is used to secure the luminaire to the
cover flange of a circular sight glass unit (also suitable for
flow indicators). Alternatively, it can be attached to the
slotted cover nut of screw-type sight glass fittings to
DIN 11851.
The bracket is fixed in place by turning the supplied ‘M8‘
bolt into a blind hole which has previously been tapped in
the pitch circle of the cover flange face. An additional
option is to weld the bracket on.
• Mounting with flanged adapter collar:
The flanged adapter collar fits between the glass disk and
the slotted cover nut (DIN 11851):
- Position appropriate seal between glass face and the
flanged adapter collar
- Tighten the slotted nuts
- Insert the luminaire into the flanged collar
- Please note: The Lumiglas luminaire variant for sterile
technology is slipped over the collar of the sterile
technology flange.
- Please note: Please order fastening and mounting
elements, claw spanner, etc. separately if not available.
