DS_H48SV05030_08102007 8 The input source must be insulated from the ac mains by reinforced or double insulation. The input terminals of the module are not operator accessible. If the metal baseplate is grounded , one Vi pin and one Vo pin shall also be grounded.
FEA TURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-curre nt protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modul es will automatically shut down (hiccup mode).
