6. Testing a Charging PointThe PE Pre-Test is an integral safety feature of the EVCA210 adaptor. It allows the operator to test the PE conductor for possible presence of a dangerous voltage, prior to testing the charge point.Under normal conditions, the PE conductor is connected to earth and therefore no hazardous voltage should be present. Should a fault condition occur e.g. if the PE conductor is connected to a phase or any insulation within the EVCA210 or associated plugs and cables has been damaged, then a hazardous situation may arise.With the EVCA210 adaptor connected to the charging point, touch the PE Pre-test button with a bare finger. If the LED indicator illuminates, then there is a dangerous voltage present on the PE conductor. Stop testing immediately and investigate the circuit and rectify before continuing. Do not touch any metal parts while performing this test.Possible faults are:Voltage present on PE (e.g. connected to phase)PE Missing or disconnected If the operator is isolated from ground through rubber matting or wearing gloves etc. the touch-test result will be unreliable and an alternative method should be employed to confirm the PE connection.7. Electrical TestingThe EVCA210 gives the operator the ability to connect their electrical test equipment to the charging point under test, in a controlled and safe manner, and to undertake the electrical safety testing of the charge point and its associated circuits. With the correct cable connected and the EVCA210 CP and PP settings correctly set (see below for details), the operator can connect either single or multifunction test equipment to the adaptor to undertake the following live tests:Earth loop impedance RCD operation Phase sequence Proximity Pilot - PP State www.megger.comEVCA210 10Testing a Charging Point
