Chapter 3 Startup
AFE in IP21 Rittal Enclosure This procedure requires that a HIM be installed. If an operator interface is not
available, remote devices must be used to start up the AFE.
Startup Procedure
Before Applying Power to the AFE
1. Verify that the disconnect lever is pushed to off.
2. Confirm that all wiring to the AFE (AC Input, ground, DC bus, and I/O)
is connected to the correct AFE terminals and is secure.
3. Verify that AC line power at the disconnect device is within the rated value
of the AFE.
4. Verify that the control power voltage is correct.
5. When DC disconnects are used for each inverter, verify that the
disconnect levers for all inverters are set to off.
6. Set the MCCB CONTROL switch to MAN.
7. Set the 0-1-START switch to 0 (off ).
Programming the AFE
1. Push the AFE disconnect lever to on.
2. Set parameter 091 [Reset To Defaults] to the appropriate setting for your
installation.
3. Use the HIM to enter the Assisted Start-up procedure.
See Figure 37 for the Active Front End start-up procedure.
091 [Reset to Defaults]
Resets parameters to factory defaults except parameters 093 [Language] and
090 [Param Access Lvl].
0 (Ready) = A new value may be entered.
1 (Factory) = Resets parameters to factory defaults.
2 (Low Voltage) = Resets parameters to factory defaults and configures parameters for a:
• 400/480V AFE unit for 400V operation.
• 600/690V AFE unit for 600V operation.
3 (High Voltage) = Resets parameters to factory defaults and configures parameters for a:
• 400/480V AFE unit for 480V operation.
• 600/690V AFE unit for 690V operation.
NOTE: The DC bus voltage must be present to set the voltage class.
