L1 S L2 L All measuring inputs (L1, L2 and L3) must be connected to phase 3N~ 1~ L3 voltage. N N If single or 2-phase monitoring is required, unused input terminals (L) N L3 N L3 must be connected to mains voltage to have proper L-N voltage on the terminals L1, L2 and L3. L1 L2 L1 L2 A phase failure can not be detected, if the reverse voltage coming from the load exceeds the threshold U . 11 11 S R R Test function (optional) 12 14 12 14 The test function enables a manually disconnection of the output relay. 11 11 Undervoltage monitoring 12 14 12 14 The output relay R switches into on-position (yellow LED illuminated), when the measuring voltage of all connected phases exeeds the fixed threshold U by more than the fixed hysteresis H. When the voltage of S one of the connected phases (L1, L2 or L3) falls below the fixed threshold, the output relay R switches into off-position again (yellow LED not illuminated).
