This parameter gives the phase rotation of the L1, L2 and L3 terminals, with relation to E1 and E3 when voltage is first detected on L1, L2 and L3.
A supply loss trip will result if a phase is missing.
Example
L123 E21 phase rotation on L1, L2, L3 is clockwise, terminal E1 is connected to the same phase as L2 terminal, terminal E3 is connected to the same
phase as L1 terminal.
The input frequency measured on the auxiliary terminals.
