Load power supply (L+, M)
Here a 24-V load power supply must be connected. The unit will not operate if the
poles are reversed.
Note
Note the SIMATIC setup guidelines. In particular, the M terminal (reference poten-
tial) must be connected with the chassis ground of the programmable controller
(M terminal on the terminal block of the S7-300 CPU).

Danger
The 24 V load power supply should be a functional extra-low voltage with safe
isolation to EN60204-1, Section 6.4, PELV (with M grounding).
Note
Make sure that the interconnecting cable between power supply and load power
supply connection L+ and appropriate reference potential M does not exceed a
max. permissible length of 10 m.
