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.
lists the recommended cross-sectional areas for power cables. Note that the currents
listed are measured at a rated voltage of 380 V.
