Multiple Modules and Power Sources

If you are installing a two-module system, both modules must be connected to the same,
grounded power source (for example, to the same electrical service entrance or breaker
box). See "Power Supply" on page 21 for the amount of current each power supply
draws.
Modules may be on separate circuits, but the circuits must be connected to the same
power source and ground. See Figure 2-1 in the section "Providing Correct Electrical
Grounding (Earthing)" on page 30 for examples of correct and incorrect power and
grounding configurations.
Caution: If you do not connect both modules of a two-module system to the same,
grounded power source, resulting differences in ground potential (current) can damage
components on the Origin200 main system board.
