14.3 Checking the earth conductor

f Check the earth conductor (in Germany e.g. DGUV A3) on the f
earth conductor contact of the power cable and on the appli-

14.4 Tests in accordance with VDE 0701/0702
Earth conductor check
f Check the earth conductor (in Germany e.g. BGV A3) on the f
earth conductor contact of the power cable and on the appli-
ance connector.
Insulation resistance
f If an appliance with a rated heating output of > 3.5 kW does f
not achieve an insulation resistance of 300 kΩ, we recom-
mend that the insulating properties of the appliance are
checked by conducting a differential current test of the earth
conductor current / leakage current to VDE 0701/0702 (Fig.
C.3b).
14.5 Replacing the power cable for the DHM 6
f If replacing the cable for the DHM 6, use a power cable with f
4 mm² cross-section
