E3YU400V02FunctionsConnectionsUndervoltage monitoring for 3-phase mains with adjustable threshold andfixed adjustable hysteresis. All measuring inputs (L1, L2 and L3) must beconnected to phase voltage. If single or 2-phase monitoring is required,unused input terminals (L) must be connected to mains voltage to haveproper L-N voltage on the terminals, L1, L2 and L3.A phase failure can not be detected, if reverse voltage coming from theload exceeds the threshold U S.Undervoltage monitoringThe output relay R switches into on-position (yellow LED illuminated),when the measuring voltage of all connected phases exceeds thethreshold U Sby more than the fixed hysteresis. When the voltage of oneof the connected phases (L1, L2 or L3) falls below the fixed threshold(green LED L1, L2 or L3 illuminated), the output relay R switches into offpositionagain (yellow LED not illuminated).1~L1NN L111R12 1412 11L221R22 24L322 2114 24UsHDimensionsRConnections45mm87mm3N~L1L2L3NNL1L2L35mm44mm60mm35mm11R12 1412 1121R22 2422 2114 24Ordering informationType Rated voltage U NSwitching thresholds U SOptions LEDs Part.
