ELECTRICAL CONNECTION

WARNINGS:
Before any work on the device, disconnect the power supply. Intervene after the elapse of 2 minutes from disconnection to
prevent possible electric shock.
Make sure the power supply cannot be accidentally restored.
Ensure that the voltage and frequency specified on the rating plate match those of the mains supply available.
Check that the current absorbed by the electric pump is compatible with the maximum current that can be supplied by the
device
Electrical connection must be performed according to the local regulations in force.
The electrical conductors must in particular be protected from high temperatures, vibrations and bumps that could cause
mechanical or chemical damage.
The power supply line must be equipped with a short-circuit protection device, a high-sensitivity residual current device RCD
(30mA class A or AC) and secured with a 16A circuit breaker for VSD EASY 9M/M and 20A for VSD EASY 6M/T and 10M/T.
The power supply line must be equipped with an external mains switch with a contact opening distance according to the
standard requirements in force.
Incorrect connections can irrevocably damage the electronic circuit.
It is recommended to use a separate power line, in order to avoid possible electromagnetic interference that can create
unwanted alterations on the electro-domestic appliances of the installation.
If electromagnetic disturbances occur it is advisable to apply a line and/or output filter.
