3.3 Grounding
Open the lid and mount the cable bushing set 18941HM. Do the grounding
according to Figure 3.3. When connecting the signal cable to the transmitter
housing, fold the cable braid between the brass disk in order to achieve the
best possible EMC performance. Do not leave the bare shield of the
connected wires so that it can shortcircuit the electronics!
(If the cable diameter is less
than 7mm, use a shrinking
tube or an adhesive tape)
