INFORMATION!
For converters with an
“ Ex e ” terminal compartment, the compartment can be opened in an
energized state for short periods of time, to access the intrinsically safe terminals for possible
checks. However, the semi-circular insulation cover over the non-intrinsically safe mains supply
terminals L and N (or L+ and L-) MUST be kept closed.
