7.3 Indication
instruments
The PSC is equipped with digital instruments (0-999) to indicate current and voltage. The accuracy is
equivalent to class1 in relation to nominal output voltage. The displays can be switched over to indi-
cate the adjustment values of monitoring thresholds. At this mode the parameter short name is
shown at the top display and its value (V

*PE is only available for PSC30, Vin=220VDC. For PSC30, Vin=110VDC, Pin 4 must be connected to
plus (+) DC input according to the table above due to the higher input current. The PE connection
(bolt M4) is available at the front plate of the module (see pictures "Front view" above).
