Motor Terminal Box Connections
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the
nameplate of the motor. This operational voltage is normally selected when installing the motor by selecting
either STAR or DELTA connection. STAR always gives the higher of the two voltage ratings.

Connecting a Brake Resistor
PACMotion VFD units feature an internal brake transistor, tted as standard for all models. The brake resistor
should be connected to the DC+ and BR terminals of the drive. These terminals are shrouded, and the
shrouding should be removed to access the terminals.
