Are you using 120v or 240v?
If 240v, it doesn't matter each leg is hot with 120v so L1 and L2 both get 120v from each terminal of the filter. If 120v, then I'm guessing P (DC+) goes to L1 but not sure if L2 gets the neutral.
The DYN4 connects to the load side
DMM said they no longer require two filters for logic and mains. They told me to just use x1 10a filter per drive to filter both. I'm using terminal blocks to breakout the power into two 240v pairs for both the main power and the logic.
They also told me the 1A fuse was no longer necessary.
Keep in mind these were for drives purchased in March 2019. Earlier drive may still require them.
Here is a pic from during my panel build. The red and black wires are 120v pairs making 240v. After they go through the breakers, contactors, and line reactors, they feed into the line side of the filters (partially obstructed by the BOB mezannine). From there the lines are broken into terminal blocks where they feed both the drive power (S,T) and the logic power (L1,L2).
