CAUTION
Single-phase motors (thermally
protected): Use with approved motor
control that matches motor input in
full load amperes.
CAUTION
Three-phase motors: Use with
approved motor control that matches
motor input in full load amperes with
overload element(s) selected or
adjusted in accordance with control
instructions.
