Chapter 2
wiring can be routed through the top, bottom, or right side of the right-most
bay.
Disconnect the Common
Mode Capacitors
Frame 10 LCL Filter
The Frame 10 AFE LCL filter contains common mode capacitors that are
referenced to ground. To guard against AFE damage, these devices
must be
disconnected
if the AFE is installed on a high resistance grounded distribution
system, or an ungrounded distribution system where the line-to-ground
voltages on any phase exceed 125% of the nominal line-to-line voltage.
To access the common mode capacitors, the LCL filter must be removed from
the enclosure. To remove the Frame 10 AFE LCL filter from the IP21 Rittal
enclosure, see the instructions in the PowerFlex Active Front End—Frame 10
Hardware Service Manual, publication
To disconnect the common mode capacitors, remove the jumpers that are
. For more information on ungrounded system installation,
see Wiring and Grounding Guidelines for Pulse Width Modulated (PWM)
ATTENTION:
To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged completely before you remove or install any
jumpers. Check the DC bus voltage between the +DC and –DC terminals,
between the +DC terminal and the chassis, and between the –DC terminal
and the chassis. The voltage must be zero for all three measurements.
