3. Electrical Connections
3.4. Mains connection to power circuits
The TVD 1.3 can be connected to 3 x AC 380...480V,50...60Hz three-phase
AC mains supplies without the need for a transformer. See section 3.5 for fuse
protection information.
The power and electronic supply connections are strapped at the time of
delivery. Generally, a separate connection for the power source of the
electronics is not required.
Mains voltage:
3x AC 380 ... 480 V;
±
10 %
Mains frequency:
50 ... 60 Hz;
±
2 Hz
Voltage interrupt:
Maximum 8 ms at base load and 380 V mains
voltage without additional capacitance.
There must be a timespan of > 1s between
sequential interrupts.
Voltage dips:
20 % of the peak voltage for a maximum ofone
period, with 3 x 380V; a corresponding
percentage with higher voltages There must
be a timespan of > 1s between sequential
interrupts.
