Important
The motors are equipped with inner
thermal protection with automatic
reconnection.
Before using motor speed control
systems verify the compatibility with
the motors.
Non compatible systems may dama-
ge motors or increase noise level;
the manufacturer will not be respon-
sible for model performance with
speed control systems.
Carefully inspect electrical connec-
tions of motors to power supply line.
Incorrect connections may damage
motors.
NOTE: It is possible to vary the number of
revolutions of the motor by applying suita-
ble commutation systems (not supplied).
See detail "A".
