Models BRC702-0B0. –EB0 and –EBC are
designed for Run-Brake operation on 1/4 to
1HP, 90 VDC armature motors or 1/2 to 2
HP, 180 VDC armature motors.
• Model BRC705-0B0, -EB0 and –EBC are
designed for Run-Brake operation on 1/2 to
5 HP, 180 VDC armature motors.
• For BRC702 with 180 VDC application:
Insure that jumper J2 is connected to 230.
WARNING!!!
Improper selection of J2 may result in
damage to the control.
• For BRC702 with 90 VDC application:
Insure that jumper J2 is connected to 115
for full dynamic braking. If less dynamic
braking is desired, the drive may be
operated with J2 placed on 230.
