NOTES:
(1) Wire in series with any other external fault
N.O. contacts connected to the Drive.
(2) Factory default is terminal S3 programmed
for external fault N.O. contact input (2-wire
control). If S3 has been reprogrammed to
another function, one of the other multi-
function terminals must be programmed
for external fault N.O. contact input.
For 3-wire control, connect to one of the
other multi-function input terminals and
program that terminal for external fault
N.O. contact input.
(3) Either an overload can be used in series with
the Braking resistor or a thermostat can be
configured as shown.
