3.2 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.
