Parallel use for redundancy

Recommendations for the construction of redundant power supply systems:

• Power supplies that contain a DC-OK signal contact are best suited for the construction of redundant power supply systems.
• Use this DC-OK signal contact to monitor the individual power supplies.
• For the power supplies with EtherCAT (e.g. PS2001-2420-1001) the DC-OK bit can be used for monitoring.
• Use separate grids for each power supply whenever possible.
• It is recommended to set the output voltages of all devices to the same value (±100 mV) or to leave them at the factory setting.

• In addition, parallel use must be enabled via the "PSU Features" object in index 0x8001:01 "Parallel use", see chapter "Parallel Use".
