User & Safety Instructions 2322320 ABB E236-US1.1 Monitoring relay
Description
All measuring inputs must be connected to one phase at a time. If a three-phase measurement is not performed, the measuring inputs must be connected to a phase in order to apply the required voltage to all measuring inputs. If a load causes a reversal voltage that exceeds the threshold value US, phase failures cannot be identified. A neutral conductor must always be connected!
