Installation Instruction:
The easiest way of setting up the luminaire is by using the purpose designed securing brackets available:

Ensure also that, before installation, you read the Information Sheet “Important note for users of sight glass fittings ..”

On circular sight glasses and on flow indicators the hinged bracket secures the luminaire to the cover flange face. In the case of the screwed sight glass the luminaire is secured to the slotted cover nut.

The Lumiglas Luminaire ESL 25-Ex suits the following fitting sizes:

  1. circular sight glass style DIN 28120: DN 25...
  2. circular sight glass style DIN 28121: DN 40...
  3. flow indicators: DN 50
  4. screwed sight glass style DIN 11851:
    - DN 65 using the separate upstand adapter.
    - DN 80 upwards using the hinged bracket. 

Hinged bracket:
Secure bracket on bolt circle of flange face using the M8 screw provided or by welding it on.

Adapter flange:
Adapter flange fits between glass disc and slotted cover nut (DIN 11851):

  • Lay gasket provided between upstand flange and glass.
  • Tighten cover nut.
  • Slide luminaire into upstand.
  • Tighten set screws on adapter flange.

Problem free electrical connection:

  1. ESL 25-Ex - with integral cable tail:
    - Cable is resin cast into EEx d flared cable entry gland.
    - Luminaire is ready wired internally for operation.
    - The external safety terminal (2) requires connection to a suitable earthing point.
    - Unsupported cable length should not exceed 1 m.
    - Caution! If the cable is to be changed e. g. for a different length, ensure internal wiring and cable gland internal lock nut are first loosened.
  2. ESL 25-Ex/1- without cable:
    - Cable connected through EEx d cable entry screwed gland unit.
    - Screwed cable entry gland supplied is suitable for all non-armored cable whereby proper seal is assured between gland and outer cover of cable.
    - Select correct cable to suit screwed gland assembly (1).
    - Unscrew lens ring (6) using special key (see “lamp exchange”).
    - Unscrew cable gland (1).
    - Pass cable through gland into luminaire body and secure cable cores to terminals.
    - Tighten cable gland (1).
    - Refit lens ring (6) and rotate until tight (see „lamp exchange“).
    - Connect external safety terminal (2) to suitable earthing point
Connecting cable options:
  1. works fitted: connecting cable (standard length 2 m) with integral pressure tight resin cast threaded cable entry and lock nut fitted one end. Alternative lengths available on request: 5, 10, 20 m.
  2. no works fitted cable: select cable suitable for cable gland assembly (M20 x 1,5).

At ambient temperatures greater than 40° C use heat resistant cable e. g. 4GMH4G-J3x1,5mm2.

Easy lamp exchange - thanks to lens ring design:

  • Switch off power.
  • Wait for period shown on identity plate.
  • Loosen locking screw (3) so releasing locking tab (angle) (4) to lens ring (6).
  • Using only the correct key, unscrew lens ring (6).
  • Withdraw defective lamp (2 pin).
  • Replace with new lamp (use only genuine original parts) holding it with protective material (not bare fingers) and pressing home carefully into 2 pin socket.
  • Replace and tighten lens ring (6) until pressing against ‘O’-ring.
  • Ensure tab (4) engages in its notch so that lens ring (6) is locked in position.
  • Retighten locking screw (3).
  • Switch back on.
