Wiring Installation: P Model
Notice
1. When using a speed controller,
always locate the thermostat
between the speed controller
and the line, not between the
motor and the controller.
2. For internal wiring and overload
protection on all starters, consult
the control manufacturer for
details.
3. When using thermostatic control
with a manual starter, be sure
that the electrical rating of the
thermostat is sufficient to carry
the motor current.
