Power Supply and Grounding
1) Drives are designed to be powered from standard three phase lines that are electrically symmetrical with respect
to ground (TN or TT network).
2) In case of supply with IT network, the use of delta/wye transformer is mandatory, with a secondary three phase
wiring referred to ground.
In case of a three phase supply not symmetrical to ground, an insulation loss of one of the devices connec-
ted to the same network can cause functional problem to the drive, if the use of a delta/wye transformer is
avoided.
Please refer to the following connection sample.

Mains connection and inverter output
The drivea must be connected to an AC mains supply capable of delivering a symmetrical short circuit current lower or
equal to the values indicated on table. For the use of an AC input choke see chapter 4.
Note from the table the allowable mains voltages. The cycle direction of the phases is free.
Voltages lower than the min. tolerance values can cause the block of the inverter.
Adjustable Frequency Drives and AC Input lters have ground discharge currents greater than 3.5 mA. EN 50178 species
that with discharge currents greater than 3.5 mA the protective conductor ground connection (PE1) must be xed type.
