It is essential to protect the ACS against reversed battery polarity.
3.11 E
MERGENCY STOP SWITCH
A manually operated Emergency Stop switch is usually included in the main contactor
energization circuit. When activated, the Emergency Stop switch de energizes the main
contactor, removing battery power from the power conversion section of the AC SuperDrives.
i
Note that removing power in this manner does not stop motion nor
produce any braking action. With driving power removed. Motors and
components they drive simply coast to a stop. A mechanical brake
must be used to stop vehicle motion in this situation.

EY START INPUT
The
KEY START
input (see Table 3 ) supplies battery voltage to the AC SuperDrive for its internal
processor and other functions. Power to the
KEY START
input is generally controlled by the vehicle
start key.

ENERAL
Connector K1 (Plug AMPseal 23P 770680-1, Contact 770854-1) provides the electrical interface
for all control and I/O connections to an AC SuperDrive.
Figure 16 illustrates wiring of the mating
interface connector. Refer to Table 3 for a description of the control and I/O signals.
