Diagram for a frequency converter with batteries
The single-wire diagrams for typical UPS installations are given in figures 9 to 15. The heavy lines represent the cables that

(see the table in the previous chapter for the required cross-sectional areas of the cables).
Note:
– for frequency converters, the input and output frequencies may be different (50 or 60 Hz);
– for frequency converters, the input and output frequencies may be different (50 or 60 Hz);
– for frequency converters without batteries, ignore the battery cubicles and the + and - cables shown in the diagram.
Special case:
The UPSs can be optionally supplied with the neutral conductor not interrupted by switches Q4S, Q3BP and Q5N.
