Terminals A, B and C are 120/230V AC supply terminals. Terminals D, E and F are available
to daisychain this 120/230V AC power to other 1794-PS power supply modules. If applying
120/230V AC power to the power supply, you can also power the corresponding 120/230V
AC modules in your FLEX I/O system.
1.
Connect the 120/230V AC power to the left side terminals on the connectors on
the left side of the power supply module as follows:
2.
Connect terminal G (+24V DC) to the +24V DC terminal on the first adapter.
3.
Connect terminal H (+24V DC common) to the +24V DC common terminal
on the first adapter.
4.
Connections I and J are used to pass +24V DC power (G) and –24V common
(H) to the next adapter in the series (if required).
