Power Wiring, Configuration B
Motor phase wiring is straightforward, with the motor’s U, V, W phases con-
nected directly to the controller’s
U
,
V
,
W
studs.
CAUTION:
The sequence of the
motor phase connections will affect the operation of the emergency reverse
feature. The forward and reverse switches and the
U
,
V
,
W
connections must
be configured so that the vehicle drives away from the operator when the
emergency reverse button is pressed.
The negative battery terminal is always connected directly to the
B-
stud.
The positive battery terminal is typically connected to the
F+
stud, as shown
in Figure 4. If the main fuse in not mounted on the controller,
F+
is not used
and the positive battery terminal is connected to the
B+
stud.
Standard Control Wiring, Configuration B
Wiring for the input switches and contactors is shown in Figure 4; the 24-pin
connector is shown in more detail below.
The controller can be programmed to check for welded or missing contactor
faults and uses the internal main contactor to remove power from the controller
and motor in the event of various faults, including reversed battery polarity.
