This information applies only to special versions! the polarisation plane is marked on the instrument. VEGAPULS 68 is also available in versions where the antenna has a bigger diameter than the process fitting (thread, flange). The antenna must therefore be disconnected from the process fitting before mounting.
10 Tighten locknut (2) with SW 36, torque max. 40 Nm. Note: Take note for VEGAPULS 68 with rinsing air connection that the holes in the antenna and in the process fitting correspond. This ensures a sufficient air flow (the air is led through the holes to the feed system. A rinsing of the parabolic antenna in total is not intended).

Tip: sensors is not possible. In case of extreme dust in the antenna system, VEGAPULS 68 is available with rinsing connection e.g. for air. The air is distributed via channels in the antenna system and keeps it virtually free of dust.
Provide a reliable separation between the supply circuit and the mains circuits according to DIN VDE 0106 part 101. The VEGA power supply units VEGATRENN 149A Ex, VEGASTAB 690 as well as all 5.2 Connection procedure VEGAMETs meet this requirement.
