For connection of a load, the reference pole L- of the channel group must be used.
Although L- at terminals 7 and 12 and at terminals 13 and 18 are connected
internally to L- on the power supply input, it is strictly recommended to use 7 and
12 for outputs 1 through 4 only and 13 and 18 for outputs 5 through 8 only. EMC
testing was performed in this manner.

TIP
Inductive loads can be connected without a protection diode on
the load. However, Rockwell Automation strongly recommends
that a protection diode be fitted directly to the load to suppress
any interference voltage.
