11.1 Notes for ielectric stiffness tests
D ielectric stiffness tests the releases, inputs and outputs, are not perm itted. 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 (providing Vaux present)or the current disappears
(if self-power supplied).

Read this manual carefully and completely. The "backup" condition can signalled configuring the unit relays; using the "YO back" selection, possible
to command the "opening coil(YO)" accessory another opening device does not work.
