Just found the diagram

Hi! I need help to this diagram/connection.

1.) How do I connect MBCR and GBCR respectively? 2.) What does G and M means in Electrical Interlock? 3.) Do I need extra relay to be able to connect MCBR to a normally close contact?

There is a note: Mains break closed output should be configured for de-energise close mains, and use the normally closed contacts of MCBR

Am I right with the connection? Let me know if I am wrong.

For Mains: 1.) From 29 connect to a normally close contact (external?) Then out from normally close contact and connect to 32 OR 2.) From 29 connect to 8 then from 8 to battery negative which is number 1 and from 1 to neutral number 32

For Generator: 1:) From 25 connect to 7 then from 7 to battery negative which is number 1 and from 1 to neutral number 28

I think this diagram/connection will make the Generator to Auto Start if it detects no power in Mains and Auto Stop if it detects there is power in Mains.
