CAUTION
3RB22 / 3RB24 and 3RB29 are not designed for use in hazardous
areas. When used in potentially explosive areas, 3RB22 / 3RB24
and 3RB29 devices must be adapted according to the respective
ignition protection type.
The 3RB22 / 3RB24 is not designed for load-side operation at
frequency converters.
NOTICE
Brief power failures (voltage drops) < 150 ms at the 3RB22 do not
lead to a protective system failure.
Long power failures (voltage drops) >150ms at the 3RB22 cause
the output relays to be deactivated.
NOTICE
Brief power failures (voltage drops) <89ms at the 3RB24 do not
lead to a protective system failure.
Long power failures (voltage drops) >89ms at the 3RB24 cause
the output relays to be deactivated.
