700L Frame 2 Common Mode

Choke Kit

(Catalog Number SK-L1-CHK2-F2)

Where this Kit is Used

The SK-L1-CHK2-F2 Common Mode Choke Kit must be installed with
PowerFlex 700L Frame 2 drives for CE compliance (EN 61800-3). When
installed at the drive AC power input and drive motor output, the common
mode choke kit helps to guard against interference with other electrical
equipment (programmable controllers, sensors, analog circuits, etc.).

What This Kit Contains

Each Common Mode Choke Kit includes two Common Mode cores with
integral mounting brackets for the input power cables and two clamps for
the shielded motor cable.

Installation Guidelines

Each assembly should be mounted as close to the drive as possible while
leaving sufficient distance between the assembly and the drive to provide
clearance for cables and leads to be installed at the drive. Mounting
dimensions for the choke assembly are provided at the back of this
publication.

Mounting and Wiring

To install the choke assembly, follow these steps:

1. Turn off and lock out input power. Wait 5 minutes.

2. Verify that there is no voltage at the drive’s AC input power terminals.

!

ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has completely discharged before
performing any work on the drive. After removing power to the
drive, wait 5 minutes for the bus capacitors to discharge. Remove
the cover of the drive. Measure the DC bus voltage at the DC+
TESTPOINT and DC- TESTPOINT sockets on the front of the
drive beneath the drive cover. The voltage must be zero.
