Selection of a suitable BaseUnit
①
Light-colored BaseUnit: Configuration of a new potential group, electrical isolation from adja-
cent module on the left. The first BaseUnit of the ET 200SP is usually a light -colored BaseUnit
for feeding the supply voltage L+.
Dark-coloredBaseUnit: Continuation of the internal power and AUX buses from the adjacent
module on the left.
②
Additional terminals: 2×5 internally bridged terminals for individual use up to 24 V DC/2 A
