Power Wiring for Compound Motor
The field must be wired between
. The internal plug diode in the 1207B is connected between
A2
therefore, the armature and field positions cannot be interchanged.
If the shunt is rated for under 2 amperes, it can be connected directly
to the controller as shown in Figure 4. If the shunt is rated for higher than
2 amperes, a contactor must be used to control the shunt field.
Control Wiring for Compound Motor
Control wiring for the compound motor application is like that for the standard
(series motor) wiring. The main contactor, if one is used, is normally connected
directly to B-.

The throttle shown in Figure 4 is a 5kΩ–0 type. Various other throttles can
also be accommodated, and are discussed in the throttle wiring section.
Polarity protection diodes and control fuses must be sized appropriately
to handle the increased current from the shunt field.
