Connect External Synchronization

The maximum voltage for external synchronization is equal to the input voltage range given in the specifications. The non-Class 2/non-SELV cables for external synchronization shall be a jacket cable and rated for 600 VAC.

  1. Route the external synchronization cables through the top or bottom of the I/O cabinet to 0P6549 as shown in Prepare for External Signal Cables.
  2. Connect the three phases to the terminal block:
    NOTE: The phases from the synchronization source must be protected by a fuse of maximum 0.5 A.
    NOTE: Do not connect the terminal block to the board. Signal cables will be connected by Schneider Electric during the assembly service.
    1. Connect L1 to J5611 on 0P6549.
    2. Connect L2 to J5612 on 0P6549.
    3. Connect L3 to J5613 on 0P6549.
