Power Connection Of Non-Regenerative Inverter Systems - HEIDENHAIN TNC 410 M Technical Manual

4.8.2 Power Connection of Non-Regenerative Inverter Systems

Standard
UL certification
Autotransformer
January 2008
The toroidal cores included in the items supplied must be mounted when
connecting non-regenerative inverter systems of the UE series. The procedure
for mounting the toroidal cores see page 5 – 38.
If you are using an UV 105 as an additional 5-V power supply, you must
connect it through an isolating transformer via separate fuses.
Details for connecting the UV 105 see page 6 – 47.
In addition to the above-mentioned components, an overvoltage protector is
required for compliance with UL requirements. See "Overvoltage Protector"
on page 4 – 9.
If the available supply voltage (L1, L2, L3, N) differs from the supply voltage
specified for the modules, an autotransformer is required to adjust the
voltages (see connection overview above). It must comply at least with the
connection specifications of the subsequent compact inverter.
