5.THE COMMERCIAL POWER SUPPLY-INVERTER SWITCH-OVER SEQUENCE FUNCTION

If the commercial power supply-inverter switch-over sequence function is activated with the FR-A5AR mounted on the inverter, the phenomenon where magnet contactor switches alternate between ON and OFF may occur.

To prevent this, adapt either connection shown below.

(1) Recommended connection example 1

Use inverter output terminals (Contact sig-

MC2

nal, open collector signal) instead of MG1

signals.

The phenomenon occurs when relay out-

put of the FR-A5AR is used as MC1 signal.
