3.3.5 Measures for higher safety categories
In many applications controls systems compliant with safety category 3 or 4
to EN 954-1 are required. Controllers of category 3 can be set up by means of
an additional group contactor which is connected in series upstream of the
motor junctions. In an emergency the control voltage for the motor contac-
tors and for the group contactor are switched off 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-31-24VAC-DC) to attain this safety category.
