Installation Guidelines 3-5
3.5 Wiring the Motor
To wire DC power to the motor, you will need to do the following:
• select appropriate wires for the armature and field lines
• connect the motor armature and motor field to the Power Module
Refer to your motor’s installation manual for additional information.
3.5.1 Selecting Wires for the Armature and Field Lines
Refer to table 3.3 for the wire to be used for armature connection and to table 3.4 for
the wire to be used for the field connection.
3.5.2 Connecting the Motor to the Power Module
To connect the motor to the Power Module perform the following steps:
Step 1. Connect the Power Module’s armature outputs, A1(+) and A2(-), to the
motor’s armature leads, A1 and A2. Refer to figure 2.5 (1250A units), figure
2.7 (1650A units), or figure 2.9 (3000A units).
Step 2. Connect the Field Power Module outputs, terminals 37 (+) and 35 (-), to the
motor’s field leads, F1 and F2. Refer to figure 3.2.
Note that for counter-clockwise rotation, connect output A1 to motor lead A1 and
output A2 to motor lead A2. Connect terminal 37 to lead F1 and terminal 35 to
lead F2.
For alternative wiring configurations, please check the motor’s installation manual.
