Terminals the same designation are connected to each other internally and identical in their functions. The
maximum load of the internal clamps UB-UB and GND-GND is 1 A each.
(A and B are each isolated with 100 nH inductivity for 12 MBaud operation).
Carefully press the cover of the inclination sensor over the sealing rubber, taking care not to tilt it.
The cover must fully rest against the base plate.
Tighten both the fastening screws firmly in the same direction.
The inclination sensor housing and braided shield of the connecting cable are only ideally connected if the
cover is resting fully against the base plate (positive locking).
