4.3.1 Selecting a PotDis-BaseUnit
Selection of a suitable PotDis-BaseUnit potential distributor module
①
Light-colored PotDis-BaseUnit: Configuration of a new potential group, electrical isolation from
adjacent module on the left. The first BaseUnit of the ET 200SP is usually a light-colored Ba-
seUnit for the incoming supply voltage.
②
P1 terminal: 16 internally bridged terminals for individual use up to 48 V DC/10 A
Example: Multiple cable connection for DI 16×24VDC ST
