1)
Single-phase connection possible. Voltage difference between phases must not exceed +/- 3,0 %
2)
All nominal values refer to a connection voltage of 400 V
With a single-phase connection, the rated DC link voltage is reduced by 35 %
3)
With a single-phase connection, the value is reduced by 66%
4)
With a single-phase connection, the value is reduced by 50%
5)
The current information depends on the controller type
Digital controller: effective value for sinus commutation
6)
For a maximum of 200 ms without preloading using E/V-controller
For a maximum of 1 s without preloading using V-controller
The load cycle must be dimensioned, that the effective value of the output current does not exceed the rated current.
7)
If UL508C has to be observed: the external ballast resistor must protect itself from overheating.
8)
Do use fuses, which have a I

s .
If UL508C has to be observed: do use fuses 32A/1000V: 3NE4 101 manufactured by Siemens (Item-No. 101 940 Baumüller). The cor-
responding fuse-carrier is available from Baumüller (Item-No. 101 960). You may even use UL-approved fuses listed in the table below.
In the table below we have listed UL-approved fuses and fuses that are not UL-approved. Please observe, that the listed fuses are of
different design and that you have to use corresponding fuse-carriers. Not all fuses listed below can be inserted into the above listed
fuse-carrier from Baumüller!

The output voltage is a pulse-commutated DC. The setting range refers to the r.m.s. value of the fundamental wave.
10)
R.m.s. value at an ambient temperature of 45 °C.

The rated output current must be reduced between 45 °C and 55 °C. The rated output current is calculated according the following
