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.
