S120 with SLM 5KW problem

Im working with a S120 (CU320-2PN), SLM 5KW and Double Motor Module. I did all the steps for the online comissioning and that stuff.

I have in my starter the CU, the two Servo (double motor module) and some configuration for my wiring.

I have some doubts.

1- Who controls the Line Contactor? Im using my DO 8 from the CU320 to energice the Line Contactor,but when I try to do the interconnection in the Input/output screen, it ask me to select the device and I dont have a infeed configuration in the starter. Should I select Servo 1 or Servo 2?

2- The same for the Contactor Feedback, Im using my DI 9, should I select servo 1 or servo 2?

3- And the most important. The signal EP for the SLM 5KW, one manual (attach 1 "manual 1") tells me to conect the EP signal to an aux contact for the Main Disconnecter, directly to the 24VDC from a Power Supply... Another manual (attach 1 "manual 2", same PDF) tells me to connect the EP signal to the same aux contact, but that signal should come from a DO of the CU320, but it doesnt say the configuration for the DO. The two manuals are from 01/2011 date. Which configuration is the right one.

Please Help.

Thanks
