1734-IA4 Confusion

Hello All, I will first state that I am very new to the world of PLC's.
I do the control drawings where I work.
I'm trying to figure out the 1734 Point IO, specifically the 1734-IA4.

The manual states "Module power is supplied from the internal power bus".
Does this mean I do not need to run ANY power wires to the modules?
The installation manual shows points 4,5,6 and 7 as "L1" wires??

The system I am designing, from left to right has the following:
1794-PS13, 1734-AENT, 1734-FPD, Followed by Qty. 11 1734-IA4's.
I'm bringing 120VAC and 24VDC to the 1794-PS13.
From the 120VAC terminals, I run wires to the FPD.
From the 24VDC terminals, I run wires to the 1734-AENT.
On the first 1734-IA4, I would think I should bring any power there, because its already back plane fed...….correct? Or DO I run power wires there? Thanks in advance

LoganB, thanks for replying so quickly. That is what confuses me...….on page 16, it shows the IA4 wiring. Terminals 4,5,6,7 are all designated "L1". Does that mean I bring power to the module?

Welcome to the forum! Sorry if you read my previous post that I deleted, I realized you had already been working from the manual.
