Restarting a DC-DC Converter Following A High Voltage Shutdown

To restart a DC-DC Converter Module following a high voltage shutdown, remove the Convert Module from the
shelf, wait 5 seconds or more, then re-insert the Converter Module. If the Converter Module immediately shuts
down a second time or fails to start, a fault condition is indicated, and replacement may be necessary. Refer to
the "Troubleshooting" section for replacement information. Refer to the "Troubleshooting" section for a DC-DC
Converter Module removal procedure.
Low Voltage Disconnect Reconnect Procedure (WHEN FURNISHED AND SET FOR

If the low voltage disconnect circuit(s) is set for manual reconnect, the battery and system output have to be
manually reconnected to the controlled load(s) when the low voltage disconnect circuit activates. (Battery
voltage must be above the upper setting of the low voltage disconnect circuit.) Perform the following
procedure to reconnect the low voltage disconnect circuits.
Procedure
1. Refer to Figure 1 for control and indicator location.
2. With "## ALARMS ACTIVE" being displayed on the MCA Interface Pad, press and release the
