(1) For parallel topologies, cables must be selected 1.5 times larger than the recommended size.
(2) Rectifier protection alone should only be considered in the event of separate inputs; if the bypass and rectifier inputs are combined,
the general input protection rating (bypass + rectifier) must reflect the recommended bypass or general protection rating.
(3) must be selective with residual current circuit breakers downstream of the UPS connected to the UPS output. If the bypass
network is separate from the rectifier circuit, or in the event of parallel UPS, use a single residual current circuit breaker upstream
of the UPS.
(4) Selectivity of distribution after the UPS with inverter short-circuit current (short-circuit in battery mode). The rating of the protection
can be increased by “n” times for series-parallel machines, with “n” equal to the number of parallel machines.
