    For this, they need to be parameterised and the unit – consisting of a switch which detects the removal of the terminal cover – has to be installed. It can be ordered from Landis+Gyr, part number 74 766 0163 0. Whenever the terminal cover is removed, the terminal cover detection de- tects the switch status change via control input 1 and enters event 13 in the event log with date and time.
