If you mount the motor starter to the right of a 15 mm or 20 mm I/O module or immediately next to a
head module, use a dummy module. You will find further information in "Selecting motor starters with
a suitable BaseUnit (Page 40)."

If higher values (2 kV (phase to ground) or 1 kV (phase to phase) are required, you will need an addi-
tional external protective circuit (see Designing interference-free controllers
