1. Basic information on fieldbus connection
Electrical connection The electrical connection of the actuator must be opened to be able to connect the
fieldbus cables.
RefertoOperationinstructions “Multi-turnactuatorsTIGRONTR-M30X –TR-M1000X”
(Y009.100), “Electrical connection”chapter.
The “Electrical connection”chapter of the operation instructions fully applies
to the connection of the fieldbus cables.It is imperative to heed the safety and
warning instructions of this chapter in particular.

Cable recommendation
Only cables complying with IEC 61158 or IEC 61784, cable type A, may be used for Profibus DP wiring.

Prior to installation, please note:
●Connect maximum 32 devices to one segment.
●If more devices are to be connected:
- Allot devices to different segments.
- Connect segments using repeaters.
●Install fieldbus cables at a distance of minimum 20 cm to other cables.
●If possible, fieldbus cables should be laid in a separate, conductive, and earthed
cable tray.
●Ensure absence of equipotential earth bonding differences between the indi-
vidual devices at fieldbus (perform an equipotential earth bonding).
