NOTE The maintenance, cleaning and testing work described below must be conducted correctly and on an annual basis in order qualify for claims under the EWM warranty. General When used in the specified environmental conditions and under normal operating conditions, this machine is largely maintenance-free and requires a minimum of care.
DIN EN 61010-1 Appendix A – Measuring Circuit A1. You as the user are tasked with ensuring that your EWM machines conform to the standard IEC/DIN EN 60974-4 and are tested with the relevant test equipment and measuring devices given above.
Maintenance and testing Test 7.3.2 Scope of the test a) Visual inspection b) Electrical test: measurement of • open circuit voltage • insulation resistance, or alternatively • leakage currents • protective conductor resistance c) Functional test d) Documentation 7.3.3 Visual inspection The key areas in the test are: 1.
Note: Even if the leakage current measurement according to the standard is only an alternative to the insulation resistance measurement, EWM recommends always performing both measurements, especially following repair work. The leakage current is based for the greater part on a physical effect other than the insulation resistance.
