5. Ensure that all conductors are correctly connected.
6. Ensure that the conductors sit securely in the terminal points.

6.12 Connection to the multifunction relay X12/X13

6.12.1 Digital output X12/X13 (MFR)

The multifunction relay (MFR) is a digital output that can be specifically configured to the system.
The three digital outputs X12 and X13 are change-over contacts via which the appropriate remote
terminal can be controlled.
In a system with multiple SMA Data Managers, you must carry out the connection to the
multifunction relay of the System Manager.
