Visually check the test object or installation before executing the safety tests. The function of the visual

inspection is to ensure the electrically safety of the latter parts. Check wires, cables and components for
possible damages. If any damage has been noticed, it isn’t allowed to perform any tests before a technical
qualified person has repaired the test object or installation . The visual inspection is executed by the
operator.
