Mount the enclosure in such a way that it is fully supported. Note: 18" (450mm) clearance below and 6" (150mm) around required for ventilation.
Open door after turning door latches 1/4 turn counter-clockwise.
Connect motor leads to the terminal block labeled output.
Connect power leads to the terminals labeled input. Note: This may be on the optional disconnect.
Caution: Crimp or solder (NO WIRE NUTS) any connections when splicing motor leads.
can cause nuisance faults or damage to the pump and VFD.
Input, output, and ground terminals
Secure the appropriate ground wires into the lugs marked with the ground symbol. Note: 4ohms or less to earth ground recommended
Install transducer into a 1/4" NPT non-metallic
fitting and run the wire back to the VFD, up to the terminal area and cut to length. Note: Cut transducer leads to length, DO NOT coil extra wire or connect shielding ground wire.
DO NOT run transducer leads next to motor leads. If necessary, only cross transducer and motor leads at a 90 degree angle.
Install the Black wire into the I1- terminal and the remaining White or Red wire into the I1+ terminal on the control board.
