Place the POWER switch to the ON positffn.
The rectifier should start and deliver output
voltage within the range of 48 to 54 VDC.
Observe the front panel meters and indica-
tors. Verify that rectifier operation is normal
after restart.

startup procedure is required. Perform the following
procedure to restart the rectifier in this event. This pro-
cedure will require an external 48 VDC power supply
capable of furnishing 10 amperes of current.
