4.4.4 Optional Dynamic Brake Hardware Size B & C Controls
If optional DB resistor is to be used, connect it to the + and BR terminals, (see Figure 4-2). Dynamic Brake (DB) Hardware
must be installed on a flat, non-flammable, vertical surface for effective cooling and operation. The DB Resistors get
extremely hot during normal operation and must be mounted away from flammable surfaces and unsafe atmosphere.

For UL compliance Motor Cable to be Copper 75°C and Fuse current rating defined by ratings marked ( )*.
Wire size is based on 40°C ambient and fuses are based on 45°C ambient, max continuous output and no harmonic current.
4.4.5 Motor Connections
All cables must be shielded and the shields must be grounded at the enclosure cable entrance.
1. Remove covers. Cover removal is described in Chapter 3 of this manual.
2. Connect the Motor leads to terminals U, V and W (see Figure 4-2 for location).
3. Connect the motor ground wire to the ground terminal (See Figure 4-2).
4.4.6 Long Motor Leads
The wire leads that connect the motor to the control are critical in terms of sizing, shielding and the cable characteristics.
Short cable runs are usually trouble free but fault-monitoring circuitry can produce numerous faults when long cables are
used. Refer to Table 4-1 for maximum cable lengths. Baldor recommends adding an optional load reactor to the output of
the control. The load reactor and/or common mode choke should be placed in close physical proximity to the control.
