4.3. CURRENTS AND SUGGESTED CABLE SIZES

Use cable cross section and fuses according to Table 1 on page 15.
If UPS is supplied from one mains only:
Connect the mains supply cables to the UPS terminals U1, V1, W1, N. The following jump-
ers must be fixed between the terminals: U1-U2, V1-V2, W1-W2 and N1-N2.
If UPS is supplied from two mains:
Connect the mains 1 supply cables to the UPS terminals U1, V1, W1, N1.
Connect the mains 2 supply cables to the UPS terminals U2, V2, W2, N2.
Connect the load to UPS terminals U3, V3, W3, N. The conductor cross sections apply for
maximum currents:
1). For PVC-insulated copper cables (at 70 °C)
2). When routed in conduits for electrical installations
3). When air temperature surrounding the conduits does not exceed 30°C
4). For cable lengths up to 30 m
5). For stranded wires up to 35 mm
Notice
Should there be any variation in the conditions it will be necessary to verify whether the cable di-
mensions satisfy the requirements of IEC-287 and DIN VDE 0298. In cases where the cables are
so long that they cause a drop in voltage of >3%, a larger dimension shall be selected.
If predominantly non-linear loads are present in your system, the neutral conductor (N) carries
1.6 times the current of the other conductors.
Routing of cables (e.g. mains cables, communication or data lines) to other equipment should be
kept separate from that of the UPS (input, output, and external battery cables).
