Where this Option is Used
What this Option Contains
What these Instructions Contain
The 1321-M Common Mode Choke Options can be installed with
1305, 1336 Plus, 1336 Plus
AC drives. When installed at the drive output the common mode
choke helps to guard against interference with other electrical
equipment (programmable controllers, sensors, analog circuits, etc.).
In addition, reducing the PWM carrier frequency reduces the effects
and lowers the risk of common mode noise interference. The table on
page 2 details the common mode chokes available for each drive
rating.
Each 1321-M Common Mode ChokeKitincludestheCommonMode
core and a mounting bracket where applicable. Some models also
contain a terminal block and wiring.
These instructions contain the information you need to properly
install a 1321-M Open Style Common Mode choke. Recommended
mounting and connection procedures are included. Major topics and
page numbers are listed below.

Installation
All choke assemblies should be mounted as close to the bottom of the
drive as possible while leaving sufficient distance between the choke
assembly and the drive unit to provide clearance for cables and leads
to be installed at the drive. All choke assemblies with the exception of
the M001 and M009 are supplied with mounting brackets. Mounting
dimensions for each assembly are provided at the back of this
publication. It is recommended that M001 and M009 assemblies be
tie wrapped to a solid object such as cabinet sheet metal or brackets
when wiring is completed.
M001 Mounting and Wiring
To install the choke assembly, follow these steps:
1. Remove all power connected to the system.
ATTENTION: Electric shock can cause injury or
!
2. Wrap the communication cable thru the choke assembly five
times as shown in the following figure. If the wire gauge is too
large to allow 5 wraps, you may use fewer wraps but this will
diminish the effectiveness of the installation.
death. Remove all power before working with this
product. Verify that the voltage on the bus capacitors
has discharged. The voltage must be zero.

3. Leave enough cable between the choke assembly and the drive to
allow the communication cable suitable clearance to be
terminated at the drive and for the choke assembly to be mounted
near the bottom of the drive cabinet. When all wiring is
completed, zip tie the choke assembly to the cabinet sheet metal
or another suitable location to provide support for the assembly.

M009 Mounting and Wiring
To install the choke assembly, follow these steps:
1. Remove all power connected to the system.
2. A 4 position terminal strip with preinstalled TB leads is included
3. Run motor leads from the terminal strip to the T1/U,T2/V,T3/W

with M009. Install leads from the terminal strip to TB1 (T3/W),
(T2/V) and (T1/U) of your drive. Make certain to leave at least 2
inches (50 millimeters) clearance between the choke assembly
and the drive terminals. Run the green 12 AWG lead from the
terminal strip
outside the choke assembly to the PE connection on
the drive TB1 as shown in the following figure.

4. When all wiring is completed, tie wrap the choke assembly to the
cabinet sheet metal or another suitable location to provide support
for the assembly. If the terminal strip supplied with the choke is to
be panel mounted, an insulation sheet must be used between the
terminal strip and the sheet metal.

M048 Mounting and Wiring
To install the choke assembly, follow these steps:
1. Remove all power connected to the system.
ATTENTION: Electric shock can cause injury or
!
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.

To install the choke assembly, follow these steps
1. Remove all power connected to the system.
ATTENTION: Electric shock can cause injury or

2. Mount the M180 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 T1/U, T2/V, T3/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 DrivePower
Earth @ TB1-PE.

4. If possible, wrap each lead once around the core before
terminating at the drive terminals. If the motor lead gauge is too
thick to allow one wrap, run the leads straight thru the choke
assembly to drive terminals TB-1, U (T1), V (T2) and W (T3) as
shown in the following figure. Running the motor leads straight
thru the core, will diminish the effectiveness of the installation.
