This section shows typical chassis drive connections.
Multiple fixed speeds
Replace the speed adjust potentiometer with series resistors
with a total series resistance of 10K ohms (Figure 14). Add
a single pole, multi-position switch with the correct
number of positions for the desired number of fixed
speeds.
Application Notes
Figure 14. Multiple Fixed Speeds
ATTENTION:
The equipment is at line voltage when
AC power is connected. Disconnect and lockout all
ungrounded conductors of the AC power line. Failure to
observe this precaution could result in severe bodily
injury or loss of life.
