lead to a protective system failure.
Long power failures (voltage drops) > 150 ms at the 3RB22 cause
the output relays to be deactivated.
NOTICE
Brief power failures (voltage drops) < 89 ms at the 3RB24 do not
lead to a protective system failure.
Long power failures (voltage drops) > 89 ms at the 3RB24 cause
