700L Frame 2 Common Mode
Choke Kit
(Catalog Number SK-L1-CHK1-F2)
Where this Kit is Used The SK-L1-CHK1-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 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 the Common Mode core with an
integral mounting bracket.
Installation Guidelines Each choke assembly should be mounted as close to the drive as possible
while leaving sufficient distance between the choke 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.
