Adjustment of the Mains Voltage
If the mains voltage is outside the range indicated in the technical
data, a transformer is required to adjust it to the power intake of the
plant.
In star point grounded networks, the voltage is adjusted by means
of an autotransformer.
In all other networks, a separating transformer is required.
CAUTION!
PacDrive PS-4 has a rated connection voltage of 230 V!
Incorrect connection voltage may result in the destruction of the
device!
 For wiring and installation, make sure that the DC-bus of
PacDrive MC-4 units with a rated connection voltage of 400 V is
not coupled with a PacDrive PS-4 unit with a rated voltage of
230 V.
 When using the unit in rotary current networks (3 AC 380...480
V), use a transformer to prevent the destruction of the
PS-4.
Wiring examples
The PacDrive PS-4 can be directly connected to grounded rotary
current networks with 3 x AC 230 V, +/- 10%. For lower
requirements, a single-phase power connection 1 x AC 230 V is
possible.
