Notes
A.1 Notes for dielectric stiffness tests
Dielectric stiffness tests the releases, inputs and outputs, are not permitted.
3. Use the “Belden 3106A”- type three-wire cable for instance (not supplied ABB SACE). the unit shows visible signs damage. the unit has been damaged transit.
2 the unit does not function (for examplewith autotest with the trip test unit).
Also remember disconnect all power supplies connected.1 afety notes

WARNING: this symbol gives information about operations, actions circumstances that can cause injuries the personnel, damage

B.
The “backup” condition can signalled configuring the unit relays; using the “YO back” selection, possible command the "opening
coil(YO)" accessory another opening device does not work.

A
Prior servicing and/or replacing, the circuit-breaker must open. 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.1.
If doubt, about its safe usage, the unit must put out service prevent any accidental use
