2. Installation
The controller is designed for either panel (cut-out 138 x 138 mm) or DIN-rail installation. It is
locked to the rail by a screwdriver-operated fixing spring and to a panel by a side fitting spring.
There are two ways of connecting the controller to the network.
Voltage LN (Line – Neutral) (CT on the same line phase)
Voltage LL (Line – Line) (CT on the third phase)
Incorrect connections can be automatically corrected by the controller when Auto Setup is
selected from the main menu.
Caution: For use in HV network, look first at chapter 6.3
