1321-M Common Mode Chokes 9
M670 Mounting and Wiring
To install the choke assembly, follow these steps:
1. Remove all power connected to the system.
2. Mount the M670 Choke Assembly on a metal surface near the
bottom of the drive cabinet using 1/4-20 hardware. Leave
sufficient clearance between the choke assembly and the drive
terminals to allow access to the terminals and provide proper
bend radius for the leads.
3. Terminate the motor leads at the U,V,W connections on the motor
as shown in the figure on the following page. An optional
terminal strip may be used between the choke assembly and the
motor if desired. A properly sized ground conductor from the
motor frame is also required. The ground conductor is routed
around (not through) the choke and connected to the Drive Power
Earth @ TB1-PE.

ATTENTION: Electric shock can cause injury or
