To suppress conducted interference, the conductors for the 24 V NC and 24 V
PLC output voltages (X90 of the PSL) must be passed through a toroidal core
(ID 309694-07, inside diameter 14 mm). There are different ways to do this
depending on the PSL variant:

Variants 02 and 03 of the PSL 130, variant 01 of the PSL 135
The toroidal core is included with the PSL. The output lines of connector X90
(24 V NC, 24 V PLC) must be passed through the toroidal core in order to
suppress conducted interference. The lines must not be wound around the
toroidal core, however.

Variant 02 of the PSL 135, variant 04 of the PSL 130
The toroidal core is integrated in the unit. No further external measures for
noise suppression must be taken.
