Insulation resistance tests (wiring): Action/check Perform insulation resistance test on all control wiring Acceptable criteria Tested using 1kV DC test voltage. Between AC to E > 5.0 MΩ between DC to E > 5.0 MΩ between AC to DC > 10 MΩ on DC bus (if any) > 0.1 MΩ on Pilots (if any) > 0.25 M Initials Results Click here to enter text. 4. Power frequency with stands voltage tests (wiring): Action/check Acceptable criteria Initials Results Perform insulation resistance test on all control wiring: Perform power-frequency withstand voltage of 2kV for 1 min, given as follows: All new wiring installed at site. All wiring not tested for PFWV in factory. All wiring disconnected and removed for transport. Note: If wiring has to be taken off or if electronic devices are in circuits, these circuits shall not be tested). Conducted/tested/ inspected by FAE 3407 June 2015 Service no.
