- Carefully pull out the cable and supply flange to the rear and strictly vertically/per-
pendicularly (see Figure 6-4). There is a risk of side tilt! Because of negative pres-
sure, it may be difficult to remove the flange.
- The circular cylindrical clearance fit
H8f7
or
H8G7
(in accordance with ISO 286) of
the lighting body and flange must not be tilted!
Risk of damage to the flame-proof
gap (DIN EN 60079-1)!
- Caution: Avoid any contact of the screw thread with skin and/or clothes! There is oil
lubricating paste applied, to protect the surface against fretting corrosion and me-
chanical stresses.
- Attention: Use particular care when dealing with installed components (camera
module, optics, temperature control, electronics, etc.) which are fixated above the
mounting adapter on the cable and supply flange (cable gland). Risk of damage!
- Attention: When removing the flange, ensure that the Gylon flat gasket (Style 3504,
blue) does not get damaged or dirty!
- After the completion of the work at the components which are installed inside the
luminaires, immediately re-close the housing. Ensure that no foreign objects and
particles are enclosed in the housing!
- For closing the housing, follow the instructions for opening the housing in reversed
order. Please observe the following safety warnings:
Attention!
Insert the flange to reach the end position, in order to ensure ignition
protection and the protection level (IP) of the housing.
Attention!
If the bolted connections are tightened too strongly, it can cause dam-
ages to the device!
Attention!
Do not to damage the surface of the drill hole and the shaft (fitting) of
the flame-proof gap.
Attention!
Ensure that you do not damage the housing seals. Keep them clean.
