Interlock Castell Function: Terminal Block X1 - ABB Conceptpower DPA 500 User Manual

10.7.3 Interlock castell function: Terminal block X1

This function allows a secure transfer from inverter (normal operation) to external maintenance bypass and vice-
versa. During normal operation the external bypass is locked in position OFF. Only when the UPS is/are transferred
to static bypass mode, the lock on the external bypass is released and it possible to switch to position ON. The
transfer from maintenance bypass back to normal operation happens exactly the other way around. The release
signal is 230VAC when the maintenance bypass is free and 0V when locked.
