} 208 – 240 V mains supplies without earthed star point (asymmetrically earthed or un-
earthed mains supplies), see Fig. (2) – (6)
} 208 – 480 V mains supplies with earthed star point, see Figure (1)
Connection via isolating transformer
} 400 – 480 V mains supplies without earthed star point (asymmetrically earthed or un-
earthed mains supplies), see Fig. (7) – (11)
Requirements for isolating transformers
} An earthed star point must be available on the secondary side. The star point on the
secondary side must be earthed and must be connected to the servo amplifier's protect-
ive earth conductor. This will prevent overvoltages between the external conductors
and the servo amplifier housing.
} The isolating transformers must have the relevant input and output voltages.
Line choke
INFORMATION
A 3L line choke with u
k
= 2% must be used in the event of a mains voltage
imbalance of > 3%. Install the line choke on the mounting plate in a way that
is EMC-compliant.
