HD65 & HD130 STEPPER DRIVES USER GUIDE 5TransformerPrimaryConnections
Standard Digiplan mains transformers for HD series drives have a
four-winding primary arrangement as shown below. The table
shows the primary voltages which can be selected, the sample
connections being for 240v AC. Always wire the transformer primary
first, then check the secondary output voltages on open-circuit
BEFORE connecting to the drive.
