EMI filter is optional but is mandatory for IEC/EN62920 standard compliance which is required in Europe.
3.
Ground connection should be common for MOV, drive, and pump.
Note: ACQ80-01 drive is intended to be used for speed control of 3-phase AC pump motors and is powered from either AC
Grid or DC photo-voltaic array. ABB recommends not to use it as an island grid forming inverter or to supply generic single
phase or 3-phase loads, other than the 3-phase AC pump motors.
