POWER LINE CONNECTION
6.1 Mains connection
The FAGOR DDS system is designed to be connected to a three-phase
line voltage of between 400 (1-10 %) V AC and 460 (1+10 %) V AC and a
line frequency between 48 ... 62 Hz. Furthermore, note that the ACD/SCD
compact drives are also designed to be connected to a three-phase line
voltage of between 200 (1-10 %) V AC and 240 (1+10 %) V AC.
Connecting it to a different voltage range requires the use of transformers
or auto-transformers.
The connection may vary depending on the type of mains and
electromagnetic compatibility required by the machine.
If the type of mains does not require isolating transformers and they only
require a voltage adaptation; we recomment to install auto-transformers
instead of isolating transformation.
Certain mandatory protection devices must be added to the lines that extend
from mains to the FAGOR DDS system. Others are optional.
WARNING.
NEVER connect a FAGOR DDS system with energy
regeneration (i.e. with XPS or RPS power supplies) in mains isolated from
general mains (generators, emergency power generators, etc.). In these
cases, always install a FAGOR DDS system with non-regenerating power
supplies (i.e. with PS power supplies).
