Typical Brakemotor Wiring
Illustrated below is a typical brakemotor wiring schematic. Note the rectifier shown is supplied in the motor conduit box. Due to changes in design
features, this diagram may not always agree with that on the motor. If different, the motor diagram found inside the conduit box cover is correct.
• New dual voltage rectifier can be wired for 230V or 460V supply.
• Solid lines show the wiring connections for standard brake action.
• For fast brake action connect terminals as indicated by dotted lines. Add an additional contactor, and varistor
VR from Figure 14 below. Do not connect terminal N on brake coil to terminal 3 on rectifier for fast brake
action. For 460V fast action braking do not connect terminal N on brake coil to terminal 2 on rectifier.
