All measuring inputs (L1, L2 and L3) must be connected to phase voltage. If single or 2-phase monitoring is required, unused input terminals (L) must be connected to mains voltage to have proper L-N voltage on the terminals L1, L2 and L3. A phase failure can not be detected, if the reverse voltage coming from the load exceeds the threshold US. L1 L2 3N~ L3 L N N Test function (optional) The test function enables a manually disconnection of the output relay. Undervoltage monitoring The output relay R switches into on-position (yellow LED illuminated), when the measuring voltage of all connected phases exeeds the fixed threshold US by more than the fixed hysteresis H. When the voltage of 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). 1~ N L3 L1 L2 N L3 L1 L2 11 R 11 R 12 14 12 14 11 12 14 11 12 14 Dimensions Us R 5mm 44mm 60mm 87mm 45mm H 17,5mm Ordering information Types Rated voltage UN Switching threshold Us Options LEDs Part.
