Page No.1 Notes for dielectric stiffness tests
Dielectric stiffness tests the releases, inputs and outputs, are not permitted.11.
Also remember disconnect all power supplies connected. Use the “Belden 3105A”- type two-wire cable for instance (not supplied ABB SACE). the unit shows visible signs damage. The unit has “backup-protection” function; the first command the opening solenoid does not open immediately the circuit-breaker (TC
partially fault), TRIP commands are repeatedly sent until the circuit-breaker opens.

Prior servicing and/or replacing, the circuit-breaker must open. Use the “Belden 3106A”- type three-wire cable for instance (not supplied ABB SACE).
