3.1.3 Preparing Power Cables

The UPS can generate large leakage currents. A circuit breaker that provides leakage
current protection is not recommended.

If multiple UPSs are to be connected in parallel, input and output power cables for each
UPS should have the same length and specifications.

The TN-C system is supported when the input N and PE are connected.
Table 3-2 lists the recommended cross-sectional areas for power cables. Note that the currents
listed are measured at a rated voltage of 380 V (line voltage).
