Configuration with 3SK1 safety relay and device connectors
If you use safety-related motor starters (3RM11..-.AA04 / 3RM13..-.AA04) with a control
supply voltage of 24 V DC with the 3SK1 safety relay, you can establish safe connection of
the safety-related wiring using the device connectors. Use of device connectors avoids
errors when setting up the control circuit wiring and offers savings in cable laying. In addition,
the test overhead following completion of the control cabinets is reduced. The
3RM11/3RM13 safety-related motor starters can be used optimally as output expansions in
the 3SK1 system.
