Fig. 6-2 Removing the weather protection roof (2/2) (similar illustration)
To open the stainless steel housing (T07 VA2.3.x.x) of the ExCam XF Q1785, loosen the
eight cylinder-head hexagon screws (DIN 912/ ISO 4762) together with their spring rings
(DIN 127A) on the rear side of the cable and power supply flange (see Figure 6-3). Cau-
tion: do not touch the screw threads with your skin or clothes! On the threads, there is
LOCTITE® 243™ (chemical basis is dimethacrylate ester) applied to prevent the bolted
connection from unintentional loosening because of impacts and vibrations and to seal
them tightly. It is not permitted for the customer to open the front-side sight glass flange!
There is no need of such an action.

Carefully pull out the cable and supply flange to the rear, as straight as possible. Be-
cause of negative pressure, it may be difficult to remove the flange. The cylindrical clear-
ance fit (H8f7 - DIN ISO 286) of the camera body and flange may not be tilted! Risk of
damage to the flame-proof gap (DIN EN 60079-1:2012)!
