⑬
AUX1 bus
⑦
Supply voltage 1
Warning
If you connect the AUX1 bus to common potential independently of the P1/P2 buses
(different voltages), there is no safe electrical separation between the AUX1 bus and the
P1/P2 buses.
Connecting different potentials to the AUX1 bus
Note
If you apply different potentials to the AUX1 bus within an ET 200S station, you must
separate the voltage groups by means of a power module with the TM-P15S23-A0 terminal
module.
