... You cannot use reverse-phase protection if you use control power with single-phase operation. Connect to terminals 1 and 2 for single- phase operation. Also, make sure to turn OFF the reverse-phase setting on the function setting switches. An error will occur if the SE is used with the reverse-phase setting turned ON during single-phase operation. Reverse-phase is detected in order of phase1, phase2 and phase3 of control power ...

... M Motor Note: 1. When using the (overload and open-phase) relay not necessary to connect terminal 3 (W). Also, always turn OFF the reverse-phase elements. 2. When using a model with an automatic reset, the Motor Protective Relay may not operate if there is an open phase on the power supply side of the motor circuit. ...

... CT of the SET-3@ are rectified, then converted to DC voltage, which is necessary for the SE, by the resistor at each tap, and output from the positive and negative terminals. The DC and AC component ratios in this voltage differ between the normal three-phase condition and conditions of phase-failure or unbalance ...

... Mounting When installing with an 8PFA1 connecting socket, first fasten the socket firmly to the panel with screws, then plug in the relay and secure it with a hook. Leave at least space between the relays for the hooks. Although there is no particular restriction on the mounting direction best to mount horizontally ...
