Pin Assignment
W A R N I N G! When interfacing the FAULT IN/RESET input, an open collector, tri-state
output or blocking diode is REQUIRED or damage may occur. Please see the IM483H
Plus/IM805H Plus Product Manual at www.imshome.com for more details and for control-
ling multiple Drives with One Reset.
