Power and motor connection on the M200D motor starter (in this example: M200D for AS-i)

Communication connection using AS-Interface and digital inputs and outputs

Communication connection using PROFIBUS and digital inputs and outputs

Communication connection using PROFINET and digital inputs and outputs

Power supply to the motors via the power bus with power T and double-T clamp connectors linked by power bus cables, spur lines to the field devices (motor starters), and power loop-through to the motors via motor connection cables

Power bus

The power supply to the field devices (ET 200pro motor starters, M200D motor starters) is provided via the power bus, in which the power T terminal connectors or power double-T terminal connectors are connected by power bus cables.

Feeders

From the terminal connectors, spur lines with Han Q4/2 plugs lead to the field devices, from which the motors are supplied with power via motor connection cables.

Interruption-free thanks to power terminal connectors

In finger-safe connection technology, the power T clamp connectors and power double-T clamp connectors connect the components of a feeder to the power bus. They ensure interruption-free operation, i.e. the power bus is not interrupted when the components are plugged in.
