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.
