.
4. Disconnect the R6.1 and R6.2 precharge resistor wires from the resistor
terminals on the precharge resistor assembly.
5. Remove the two precharge resistor assembly mounting screws that
secure the assembly to the bracket on the LCL enclosure bay.
6. Remove the mounting screws from the failed precharge resistor, and
appropriately discard the resistor.
7. Install the new precharge resistor in reverse order of removal. See
AFE in IP21 Rittal Enclosure
To replace the precharge resistor assembly in an IP221 Rittal enclosure, follow
these steps.
1. Remove power from the AFE.
See
Remove Power from the AFE on page 37
.
2. Open the LCL filter enclosure door.
3. If present, remove the protective barriers.

.
4. Disconnect the wires from the (+) and (-) terminals on the precharge
resistor assembly.
5. Verify that the capacitor on the bridge (+) and (-) terminals is still in the
circuit.
6. Disconnect the white wires from the terminal block by the bridge.
7. Remove the mounting screws from the failed precharge resistor, and
appropriately discard the resistor.
8. Install the new precharge resistor in reverse order of removal. See
