15.2.3 Control connections
The M12 control connections function by location, thread style, pin count and plug code vary.
15.2.3.1 Network connection
Overview Two network connections are provided for the PROFIBUS models. Both
connections have an identical function.
Both PROFIBUS connectors are joined internally to allow flexible network
configurations. If the pump is to be used at the end of a network, we
recommend the use of a PROFIBUS termination plug for maximum network
speed and robustness. To maintain ingress protection the termination plug
must be IP66, NEMA 4X rated.
Location The connections are located as
illustrated by the graphic.
