For connection to the technical earth (ground) (TE), a threaded stud with nut is provided
on the connection module. To assure electromagnetic compatibility (EMC), connect this
stud to a suitable earthing (grounding) point using as short a cable as possible
(max. 30 cm).
Use of the 4 - 20 mA setpoint input
If the voltage supply of a TOP Control Continuous device fails in a row of such devices con-
nected in series, the input of the failed device will become high-impedance. This will cause the
4 - 20 mA standard signal to fail. If this occurs, please contact Bürkert Service directly.
