Placement and connection to common potential of power
modules
Placement and connection to common potential
You can choose where to position the power modules in the ET 200S. Each TM-P
terminal module (for a power module) that you install in the ET 200S opens a new
potential group. All the sensors and load supplies of the downstream electronic
modules/motor starters 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 voltage buses (P1/P2) and simultaneously
open a new potential group. This permits connection to common potential of
sensor and load supplies.
AUX(iliary) bus (AUX 1)
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 ground bar
•
Additionally required voltage
