Hello All,

On a multilin 750, I want to block the second phase instantaneous element. It has an option to block overcurrent function, in the drop down it has different input selections. Based on the attached image:
1. When the voltage is applied/available across the INPUT-1, the contact will open. Is that correct? and the instantaneous element will not be blocked? AND
2. When the voltage is NOT applied/available across the INPUT-1, the contact will be closed. Is that correct? and the instantaneous element will be blocked?

This relay is different than other relays available where the logic can be used to invert the input which makes it easy to interpret.
