Positioning and Connecting Power Modules
An ET 200S containing fail-safe modules is no different than an ET 200S containing
standard modules with regard to positioning and connection of power modules.
You can position the power modules as you wish. Each TM-P terminal module (for a power
module) that you add to the ET 200S opens a new voltage group. All sensor and load current
supplies of the electronic modules/motor starters that follow are fed from this terminal
module.
Placing another TM-P terminal module after an electronic module/motor starter interrupts the
voltage buses (P1/P2) and simultaneously opens a new voltage group. This enables
individual connection of sensor and load current supplies.
AUX(iliary) Bus (AUX 1)
A TM-P terminal module (for a power module) allows an additional voltage connection (up to
the maximum rated load voltage of the module), which you can apply over the AUX(iliary)
bus. You can use the AUX(iliary) voltage as follows:
• As a protective conductor bus
• When additional voltage is required
