4.3.5 Measures for higher safety categories
In many applications controls systems compliant with safety category 3 or 4
to EN 954-1 are required. Category 3 control systems can be set up by
means of an additional contactor which is connected in series upstream of
the motor feeder or motor feeders. The control voltage for the contactor and
the control voltage for the motor contactors are switched off in an emer-
gency via the safety relay. This redundant disconnection circuit enables the
implementation of Category 3 control systems. The safety relay used must
comply with Category 3 or higher (e.g. ESR5-NO-41-24VAC-DC) to attain this
safety category.
