Information:
This information applies only to special versions!
VEGAPULS 68 is available in versions where the
antenna has a bigger diameter than the process fitting
(thread/flange). Therefore the antenna must be dis-
mounted on the process fitting before mounting.
Proceed as follows:
1 Loosen the hexagon screws on the antenna socket
(1) with an Allan key (size 3)
2 Remove the antenna (2)
