5.15.2 Automatic differential thermal-magnetic circuit breaker
at line inlet
This type of protection must take into consideration the leakage current in
relation to the network filters mounted on the product.
From the various tests carried out each FlexiMova
®
mm model has a different
leakage current value. It is the responsibility of the installer to select an RCD
(residual current differential) protection device appropriate for the category
of the inverter (for PWM modulation) and with protection trip threshold
calibrated according to the table below.

5.15.3 Motor PTC protections
For the line and motor connections use the respective cable glands provided.
In the event of discharge in the motor windings and the PTC connection the
system self-protects through the fuse connected in series with the same PTC.
The opening of this fuse prevents the transfer of dangerous voltage
to the part of the control that is accessible to the operator.
In the event of failure, the fuse can only be replaced by the Manufacturer.
