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, opens the battery disconnect contactor, and shuts down the -48 VDC to +24 VDC
converters. When the ESTOP signal is removed, the battery disconnect contactor closes (if battery present) and -48 VDC to +24
VDC converters restart. To restart the rectifiers; turn input power to the rectifiers OFF, wait 30 seconds or more (until the LEDs
on the rectifiers extinguish), then turn input power to the rectifiers ON.
