Powering Off the island

To de-energize the bus coupler:

  1. Disconnect upstream power to the island by removing the 24 V connection to the bus coupler.

  2. Verify that the PWR LED on the bus coupler is off.

When the bus coupler is de-energized, the following occurs:

  • All power modules (standard starters, SIL* starters, and power interface modules) and I/O modules enter the Off condition

  • All modules are de-energized

  • All contactors are set to open

  • All outputs from the I/O modules are set to zero
