PowerFlex Active Front End in IP20 2500 MCC Style Enclosure Frame 13 Right-Side Bus Splice Kit
Right-side Connection
To connect the bus bars and attach an enclosure to the right side of the AFE
enclosure, follow these steps.
Step 1: Remove power from the AFE.
a.
Turn off and lock out input power.
b. Wait five minutes for bus capacitors to discharge.
c.
Verify that there is no voltage at the AFE input power terminals.
d. 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 before
proceeding.
Step 2: Remove left side covers from the enclosure being connected to the AFE.
Step 3: Remove the AFE enclosure right side covers to access the bus bars.
ATTENTION:
To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged completely before servicing. 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.
