5 y1 U0 l5 b1 v; W( wThe unit can be used at AC mains (both units connected together) or DC (units separated, only DC/DC
used). The AC/DC unit has a (Class II) IEC 60320-1 type appliance inlet; the DC/DC unit uses a
special 2-pins input connector.
With a small force applied (less than 30 N) an IEC 60320-1 coupler can be inserted into the input
