6.6 Full Voltage
Connection
Wound Motors Only) –
Connect the motor field
leads to F+ and F-
terminals of TB3 as
shown in Figure 4, and
Table 7, on page 14.
Note: Do not connect
motor armature
leads to F+ and
F- terminals.
CAUTION! Do not use F+
and F- terminals of TB3 for
any purpose other than to
power the field of a shunt
wound motor.
6.7 Half Voltage
Connection
Wound Motors Only) –
Connect the motor field
leads to F+, TB3 and L1
terminals of TB2, as
shown in Figure 5, and
Table 7, on page 14.
CAUTION! TB3 terminals are
not isolated from AC line. Do
not ground (earth).
Note: Do not connect
