1. Undo and remove the bolted connections (M5) on the upper antenna seg­
ment.
There are fan type lock washers between the antenna segments: make
sure that they do not get lost.
2. Use an appropriate base plate to install the stator housing in the shaft train
so that there is sufficient opportunity for horizontal and vertical adjust­
ments. Do not fully tighten the bolts yet.
3. Now use two hexagon socket screws to mount the upper antenna segment
removed in Point 1 on the lower antenna segment.
Make sure that the two fan type lock washers are inserted between the antenna
segments (these ensure that there is a defined contact resistance)!
Important
To make sure that they function perfectly, the fan‐type lock washers (A5,
3-FST DIN 6798 ZN/galvanized) must be replaced after the bolted antenna
connection has been loosened three times.
4. Now tighten all antenna‐segment bolted connections with a tightening
torque of 5 Nm.
