Important instructions
In this version, the coil voltage of the power contactor is connected to the volt-
age between two external conductors of the three-phase network.
When installing a hood limit switch or an external emergency-off device, they
must be looped in at the connection points F1 (terminal 96) and contactor KM1
(terminal 14) (see section 5.1.1).
CAUTION: Danger to life through electrical voltage!
•
Disconnect the power supply to the electrical installation before connecting

•
H = manual reset, i.e. the button must be pressed prior to the re-start.
•
A = automatic reset, i.e. the motor can be directly started by means of the ON
button.
When the bimetal release responds, the power contactor KM1 switches off the
motor.
Check the motor for overload or check the rated current setting at the bi-
metal release F1.
