14.3 Tests in accordance with
VDE 0701/0702
Earth conductor check
» Check the earth conductor (in Germany e.g. DGUV
A3) on the earth conductor contact of the power
cable and on the appliance connector.
Insulation resistance
» If an appliance with a rated heating output of
> 3.5 kW does not achieve an insulation resistance
of 300 kΩ, we recommend that the insulating pro-
perties of the appliance are checked by conducting
a differential current test of the earth conductor cur-
rent / leakage current to VDE 0701/0702 (Fig. C.3b).
14.4 Appliance storage
» Store the dismantled appliance in a room free from
the risk of frost, as water residues remaining inside
the appliance can freeze and cause damage.
14.5 Replacing the power cable for the
MDO 57
» If replacing the cable for the MDO 57, use a power
cable with 4 mm² cross-section.
