PE PE Ground Refer to Figure 14
on page 40 for location on 3 Frame drives
Motor Ground Refer to Figure 14 on page 40 for location on 3 Frame drives
U U (T1) To motor
V V (T2) To motor
W W (T3) To motor
R R (L1) AC Line Input Power
S S (L2) AC Line Input Power
T T (L3) AC Line Input Power
ATTENTION: The drive does not offer protection for externally mounted brake
resistors. A risk of fire exists if external braking resistors are not protected.
External resistor packages must be self-protected from over temperature or a
circuit equivalent to the one shown below must be supplied.
