WIRING: Standard Configuration
Figures 3a and 3b show typical wiring. The system can include an electromag-
netic brake or a WalkAway
™ relay, but not both. Figure 3a shows a system with
an EM brake; Figure 3b shows a system with a WalkAway ™ relay.
Standard Power Wiring
Motor armature winding is straightforward, with the armature’s A1 connection
going to the controller’s B+ bus bar and the armature’s A2 connection going
to the controller’s M- bus bar.
The motor’s field connections ( F1 and F2 ) to the controller are less
obvious. The direction of vehicle travel with the forward direction selected
will depend on how the
F1 and F2 connections are made to the controller’s
two field terminals and how the motor shaft is connected to the drive wheels
through the vehicle’s drive train.

in an application with an EM brake.
