Note:
-48V is factory wired to the Digital Input #8 (-) terminal for your convenience and function predefined for ESTOP. Customer-
furnished system ground applied to terminal Digital Input #8 (+) activates the ESTOP function. The ESTOP function shuts down and
locks out the rectifiers or 400V DC input converters, opens the LVD’s, and shuts down the optional -48V to +24V DC converters.
When the ESTOP signal is removed, LVD’s close (if battery present) and -48V to +24V DC converters restart. To restart the rectifiers
or 400V DC input converters; turn input power to the rectifiers/converters OFF, wait 30 seconds or more (until the LEDs on the
module extinguish), then turn input power to the rectifiers/converters ON. Rectifiers/converters can also be restarted from the ACU+
LCD or WEB Interface menu (via the Rectifier Reset or Converter Reset command, found in the Manual menu in the LCD menus or
under the Rectifier or Converter Control Tab in the WEB Interface).
