The FAGOR DDS modular servo drive system is designed to be connected
to TN type three-phase mains with values within the voltage range between
400-10% and 460+10% V AC and a mains frequency of 50/60 Hz.
Connecting it to a different voltage range requires the use of transformers
or autotransformers.
The connection may vary depending on the type of mains and electromagnetic
compatibility required by the machine.
Certain mandatory protection devices must be added to the mains lines.
Others are optional.

Note. The mains filter may be installed either before or after the power
contactor - KM1.
MANDATORY.
Never connect in parallel with the DDS system other elements such as
moors, inductive components, etc. to avoid the risk of poor system performance
when stopping the machine.
Always connect the power supply of other equipment being installed and
run together with the DDS system through a second contactor - KM2 or
through auxiliary contacts of the power (main) contactor - KM1.
