8.9 Protective conductor resistance (R
PE
)
Resistance between any conductive touchable parts, connected to the
protective conductor for protective purposes, and the earthed contact of the
mains plug, the device plug or the protective conductor, which is constantly
connected to the mains power supply.
During the measurement of the protective conductor resistance, the
connecting cable should be moved, section by section, along its whole
length. This measuring method only applies for devices of protection class I.

8.10 Visual inspection
Testing in accordance with DIN VDE 0701 or 0702 also involves visual
inspection of the device.
According to the standard the devices should be inspected for external
defects (without opening the device) and, as far as possible, for suitability to
the place of installation. In particular, attention should be paid to the
following:
inspection of the device.
According to the standard the devices should be inspected for external
defects (without opening the device) and, as far as possible, for suitability to
the place of installation. In particular, attention should be paid to the
following:
– Damage to the housing
– Defects of the cord connector guard and strain relief fittings
– External damage of the connecting cables
– Unauthorised interference and changes
– Signs of overloading and improper use
– Orderly condition of the protective covers
– Safety impairing soiling and corrosion
– Unblocked cooling vents
– Existence of necessary air filters
– Leak tightness, pressure relief valve
– Legibility of safety-related inscriptions
– Fuse links in accordance with manufacturer’s specifications
