1321-M Common Mode Chokes 5
M048 Mounting and Wiring
To install the choke assembly, follow these steps:
1. Remove all power connected to the system.
2. Mount the M048 Choke Assembly on a metal surface as near as
possible to 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 T1/U, T2/V, T3/W connections
on the motor as shown in the following figure. 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.
4. Run the leads thru the choke assembly and wrap each lead around
the choke four times as shown in the previous figure before
running the leads to the drive. Each lead should be wrapped in the
same direction starting on the outside of the coil and exiting
inside the coil. If possible, maintain a 120
° separation of the lead
wraps. Install the motor leads at T1 (U), T2 (V) and T3 (W) at
terminal block TB1 on your drive.

ATTENTION: Electric shock can cause injury or
death. Remove all power before working with this
product. Verify that the voltage on the bus capacitors
has discharged. The voltage must be zero.
