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.
In
Table
3-3, the mains input power cable diameter of the UPS5000-E-240 kVA is less than
that of the UPS5000-E-200 kVA. The following describes the reason: Cables for the
UPS5000-E-(40 kVA-200 kVA) can be multi-core or single-core while those for the
UPS5000-E-(240 kVA-320 kVA) can only be single-core (single-core cables endure
currents better than multi-core cables).
lists the recommended cross-sectional areas for power cables.
