4. When using more than one DC device, you may wire all the device ground termi-
nals together, and wire the odd-numbered terminals on the 8-module rack together if
all 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-numbered
terminal on the 8-module rack.
2. Wire the NEUTRAL terminal on the external power source to one of the AC
device terminals.
3. Wire the other AC device terminal to an odd-numbered terminal on the 8-module
rack.
4. When using more than one AC device, you may wire the even-numbered terminals
on the rack together, and wire the neutral terminals on the AC devices together.
