EU Declaration of Conformity
The Wolf ATEX Turbolite meets all relevant provisions of the 2014/34/EU (ATEX Equipment) Directive by virtue of the issued EC Type Examination Certificate, and
subsequent review, confirms compliance with the essential health and safety requirements.
The Wolf ATEX Turbolite is powered with compressed air that, once regulated, drives the turbine wheel fitted to the shaft. The magnet, also fitted to the shaft, rotates
within windings, generating electricity and powering a 24v 250watt tungsten halogen bulb. The A-TL44A/B Baylight provides all round illumination; the A-TL45A/B
Floodlight gives directional illumination, with the suffix denoting A – Aluminium construction or B – Brass construction.
A-TL44A, A-TL45A, A-TL44B and A-TL45B are all approved for Group II surface applications, as Category 2 equipment, for zone 1 & 2 potentially explosive gases,
vapours, mists and dusts, where T4 temperature class permits.
Approval code: II 2 GD II T4 (Ta=55°C) T135°C
A-TL44B and A-TL45B are approved for Group I mining applications, as Category M2 equipment.
Approval code: I M2
Conditions of Certification (X)
• clean, dry compressed air must be used
• anti-static air hose must be used (≥10
• in dust atmospheres the silencer must be replaced by an anti static hose, ensuring exhaust air is piped to a safe/non hazardous area, preventing dust deposits from
being disturbed. Performance of the lamp may be reduced dependant on hose length.
These lamps are not solidly earthed, precautions against the hazards associated with static electricity should be taken.

Housing Cover Removal from Manufacturing date code 0409 (2004, September)
To remove the generator housing cover (A-216/212), remove the screws (A-18), the assembled rotor is fitted to the housing cover. Do not prise the housing cover off this
would damage the casting and 'O' ring seal. The bearing in the generator housing has an adhesive on the outer ring (see fig 1b), also the attraction of the magnet will
resist removal. Light tapping with a plastic or hide mallet on the rim of the housing cover will be required to release the cover.
Disassemble the components from the rotor shaft to get access to the bearing retaining ring (A-868) and the 3 x bearing retaining ring screws(A-873), which allow the
rotor shaft with sealed bearing to be removed from the housing cover.
Before reassembly ensure the bearing outer race and generator housing bearing bore are clean. Do not use abrasive cleaners. A small amount of loctite 222 adhesive or
equivalent thread locking adhesive should be applied to the generator housing bearing bore. Make sure that no small ferrous objects have been attracted to the magnet.
