Power connection
11.1 Direct power connection
It is possible to connect these drives directly to grounded three-phase cur-
rent lines with AC 380...480 V, +10 %. Only a fuse protector Q1, a mains
contactor K1, and normally a line filter are required in the power input line.
If the line voltage exceeds the permitted input voltage range, then the
voltage must be matched by means of an autotransformer which, in turn,
has also been laid out for a specific voltage range (see Chapter 9-1).
It is possible to connect these drives directly to grounded three-phase cur-
rent lines with 3 x AC 230 V, +10 %. A single-phase power connection 1 x
AC 230V is possible for small amounts of power.
Only a fuse protector Q1, a line contactor K1, and normally a line filter are
required in the power input line.
If the line voltage deviates from the permitted input voltage, the voltage is
usually matched using an autotransformer or for special line conditions,
using an isolating transformer (see Chapter 9-1).
