Placing and Connecting to Common Potential
You can choose where to position the power modules in the ET 200S. Every TM-P terminal
module (for a power module) that you install in the ET 200S opens a new voltage group. All
sensor and load supplies of the downstream electronic modules are fed from this TM-P
terminal module (for a power module). If you place an additional TM-P terminal module after
an electronic module/motor starter, you interrupt the potential buses (P1/P2) and
simultaneously open a new voltage group. This enables sensor and load supplies to be
individually connected to common potential.
AUX(iliary) bus (AUX1)
A TM-P terminal module (for a power module) allows you to connect additional potential (up
to the maximum rated load voltage of the module), which you can apply by means of the
AUX(iliary) bus.
You can set the AUX(iliary) bus individually:
• As a protective conductor bar
• For additionally required voltage
The AUX1 bus is laid out as follows:
• Maximum current-carrying capacity (at 60 °C ambient temperature): 10 A
• Permitted voltage: 230 VAC/DC
