4.2 Signal connection
4.2.1 Screening of the analog outputs
The interference suppressor attenuates electromagnetic effects on control, power and
signal lines.
After the connection of the data transfer cables clip the interference suppressor (in
scope of delivery) on the cable cores (not on the outer insulation of the cable!). Place
the cable screen out of the interference suppressor and connect it to PE (brass screw
with bolt, top right in the connection compartment) (
→
Fig. 12).
!
Note!
With the two-channel version, place the cable cores of all cables (data cables to analog
output 1 and to analog output 2) through the interference suppressor.
