Note: In the CLOSED method, the RUN (green) LED will remain lit
if a RUN command is present, even if unit is INHIBITED.
If the INHIBIT function is not desired, CUT jumper J1 and wire the
RUN/STOP circuit as shown in the CLOSED method. No wiring to
A1 or INHIBIT will be required.
CAUTION: INHIBIT is a logic convenience and should not be used
as an Emergency Stop. INHIBIT cannot override a catastrophic
drive failure. A system Emergency Stop function, necessary to
protect personnel or equipment, will always remove AC power
from the S1000.
