Power supply

The measuring systems only fulfil the requirements stipulated in the standard IEC 61010-1 if the power is supplied from a secondary circuit with limited power according to IEC 61010-1^{3rd Ed.}, Section 9.4 or with limited power according to IEC 60950-1^{2nd Ed.}, Section 2.5, or from a secondary circuit Class 2 according to UL1310. You can also use the corresponding sections of the standards DIN EN 61010-1, EN 61010-1, UL 61010-1 and CAN/CSA-C22.2 No. 61010-1 instead of the standard IEC 61010-1^{3rd Ed.}, Section 9.4, respectively the corresponding sections of the standards DIN EN 60950-1, EN 60950-1, UL 60950-1 and CAN/CSA-C22.2 No. 60950-1 instead of the standard IEC 60950-1^{2nd Ed.}, Section 2.5.
