Note: At DC input, always leave the switch in the 230V position. Input current To be fused with a 10A, B-type 'circuit-breaker' switch based on the usual thermomagn. overload sensing principle (used anyway to fuse the input lines). In addition, the unit contains an internal fuse (not accessible). Harmonic current emissions (PFC) acc.
