Connection Schemes

Split Phase Operation

Use this scheme to extend the output voltage. No more than two units should be connected in series though more can be added in parallel with either series unit.

To connect two units for split voltage, proceed as follows:

First ensure power to the rack has been disconnected. make connections to the CAN/SYNC connector using its screw-type wire clamps. It may be necessary to remove the mating connector to facilitate connections to the terminal

Start with the phase synchronizing lines on the CAN/SYNC connector. Wire the “SYNC_OUT 0” and “RETURN” of the first unit in the top phase to those of the first unit in the bottom phase.

To add units in parallel on either top or bottom phase, see “Parallel Operation” on page 2–15 for wiring details.

To create the Split-voltage between the top phase and bottom phase, connect the L2 terminals of the first group to L1 terminals of the second group. This node must also be connected to safety ground.

This leaves L1 of top phase and L2 of bottom phase as the output terminals. These should be connected to the load or distribution bus using a suitably rated circuit breaker.
