Basic structure of an ET 200pro version with (from the left) connection module for IM, interface module for communication (IM), RSM isolator module, two ET 200pro motor starters (MS), and connections for energy

Infeed on the ETВ 200pro motor starter

Infeed on the isolator module

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.

Motor control via PROFIBUS

The interface module (IM) for PROFIBUS can be combined with three different connection modules for connecting PROFIBUS DP and the power supply:

• Direct connection with cable glands
• ECOFAST connection with hybrid fieldbus cables (with two copper cores for data transfer with PROFIBUS DP, and four copper cores for the power supply), and ECOFAST connectors (HanBrid)¹⁾
• M12, 7/8" connection
  • with M12 connecting cable and M12 plugs for data transfer with PROFIBUS DP
  • with 7/8" connecting cable and 7/8" plugs for the power supply²⁾

For connection modules with the relevant accessories, see Accessories for ET 200pro interface modules IMВ 154-1 and IMВ 154-2.

¹⁾ Hybrid fieldbus connections with HanBrid sockets designed as cabinet bushings transmit data and energy from the control cabinet (IP20) to the field (IP65). In addition, they are also the interfaces for the joint route PROFIBUS DP and the auxiliary voltages into the hybrid fieldbus cable.

²⁾ On the cabinet bushings with two M12 sockets for the PROFIBUS M12 connecting cables, the 24 V supply of the motor starters is implemented via separate 7/8" connecting cables.

Motor control via PROFINET
