Visual inspection

General

During a visual inspection, the tests described below are to be carried out without further
dismantling of the equipment. Safety related parts must not show any visible defects. Fur-
thermore, defects which may present a danger during the visual inspection must be written
down.
Deficiencies identified that may be the cause of other hazards must be repaired immedi-
ately, otherwise further use must be restricted until the defect is rectified.

IMPORTANT! To determine the cross-section and current carrying capacity of mains ca-
bles, observe standard IEC 60364-5-52. As the current carrying capacity can vary due to
the cable layout and its insulation and differing ambient temperatures, when the mains
leads are replaced the requirements of standard IEC 60364-5-52 must be met. Individual
national requirements and standards must also be observed.
