Series C Application/Installation Considerations
Keep the following in mind if you are replacing a Bulletin 160 Series A or B drive
with a Series C unit.
Mounting Dimensions
• Width has increased by 8 mm for all ratings through 1.5 kW (2 HP).
Note: If proper spacing recommendations were followed for Series A and B
drives, the increased width should not effect the panel layout because Series C
drives of this rating do not require spacing between units.
• Width has decreased by 50 mm for the 2.2 kW (3 HP) rating.
• Depth has increased by 25 mm for all ratings through 2.2 kW (3 HP).
Note: The drive utilizes the same DIN base and mounting hole pattern for all
ratings through 2.2 kW (3 HP).
External Braking
• The internal brake transistor is not available on 0.37 kW (1/2 HP) and 0.55 kW
(3/4 HP) units. If external braking is required, a 0.75 kW (1 HP) drive must be
used.
DeviceNet
• DeviceNet modules (Catalog No.160-DN1) with Firmware Version FRN 2.0 or
earlier are not compatible with the Bulletin 160 Series C drives. Series C drives
must use DeviceNet modules (Catalog No. 160-DN2). The 160-DN2 module is
also compatible with Series A and B drives with the exception of the Series A
Preset Speed model with Firmware Version FRN 4.04.
24V DC Interface
• Bulletin 160 Series C drives must use a Series B, or later, 24V DC Interface
module. See Appendix B for catalog numbers.
Terminal Block Wiring
• The ground terminal is now located on the power terminal block. Refer to
Figure 2.2 on page 2-3 to avoid incorrect wiring.
Incorrect Motor Rotation
• The output phasing of Series C drives is different than the output phasing of
Series A and B drives. Replacing a Series A or B drive with a Series C drive
using the same U, V and W (T1, T2 and T3) connections will reverse the motor
rotation. To assure the same direction of rotation, switch any 2 of the 3 output
wires connected to U, V or W (T1, T2 or T3) from the motor.
