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.

Comm Cable

From Communication Device

To Drive

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

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.

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.

terminals on the motor as shownin the following ﬁgure. Run a 12 AWG ground lead from the terminal block to the ground point on the motor frame.

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.
