SIRIUS - SIRIUS 3RT Contactors/Contactor assemblies
74 Manual, 09/2017, A5E03656507120A/RS-AE/006
Bridging temporary voltage dips
Control voltage failures dipping to 0 V (at A1/A2) are bridged for up to approx. 25 ms to avoid
unintentional tripping.
Note
Configuration note
When in operation in or around co
nverter circuits, it must be noted that the control wiring to
the contactor should be installed separately from the load side wiring of the converter.
