DC power supply
The power supply (SELV) that is used must fulfill the requirements for
reinforced/double insulation for main supply circuits in accordance to DIN/EN/IEC
61010 (UL 61010B–1, CSA C22.2 No. 1010.1) or DIN/EN/IEC 60950 (UL 1950, CSA
C22.2 No. 950). It is recommended to fuse the DC power supply according to the
table below. Before switching on the instrument check the connection for correct
polarity.
In continuous operation the actual breaking current can differ from the rated breaking current. For fuse
selection take the characteristics of the fuse into account.
