Example UPS Supply Connection

The image shows an example UPS power supply connection to the drive that provides a supply voltage during rescue operation.



  • The Rescue Supply Contactor must only be closed when the Main Contactor is open (Interlocking Mechanism)

  • A delay time of no less than 2 seconds must be included when changing over to/from UPS supply to/from mains supply mode.

  • The Main Supply Contactor and Rescue Supply Contactor must be interlocked so that both cannot be energised at the same time, failure to do so may result in damage to the UPS and/or contactor.

  • The drive will always wait until the next stop command (direction input removal) before rescue mode operation is activated and likewise when rescue mode is de-activated the drive will wait until the next stop command before changing back to normal mains supply operation.

Warning

Circuit protection must be provided.

Note

Any Digital Input can be used to activate rescue mode not just Digital Input 8 (DI8).

To change the Digital Input for Rescue Mode use P1-02 to select a different Macro or set P1-02 to 0 and create your own Macro using Group 12 to define the function of each Digital Input.
