Chapter 5: Outputs

4. When using more than one DC device, you may wire all the device g round termi-nals together, and wire the odd-numbered ter minals on the 8-module rack together ifall the DC devices require the same voltage.

To wire an AC device to the 8-module rack using external AC power source:

1. Wire the HOT terminal on the external AC power source to an even-numberedterminal on the 8-module rack.2. Wire the NEUTRAL terminal on the external power source to one of the ACdevice terminals.3. Wire the other AC device terminal to an odd-numbered terminal on the 8-modulerack.4. When using more than one AC device, you may wire the even-numbered terminalson the rack together, and wire the neutral ter minals on the AC devices together.See diagram below:
