CAUTION
Do not overtighten the jackscrews in the following step.
Over-tightening could damage the connectors.
Secure the cable by finger-tightening the cable connector jackscrews.
Slide the cable clip along the cable and press it into the hole of the I/O module bracket.
2.4.7.3 Cabling for One Expansion Unit
For a single expansion unit, cable from the terminated side of the I/O module on the
master unit to the terminated side of the expansion unit. The terminated side is identified
by the resistor symbol, it is also the LEFT-hand connector of the SE I/O module. See
Figure 2–35.

2.4.7.4 Cabling for Two Expansion Units
For two expansion units, cable from the terminated side of the I/O module on the master
unit to the terminated side of the I/O module on the first expansion unit. Then connect
from the unterminated side of that I/O module on first expansion unit to the terminated
side of the I/O module on the second expansion unit. The unterminated side is identified
by the resistor symbol enclosed in a circle with a diagonal bar across the symbol. It is also
the RIGHT-hand connector of the SE I/O module. See Figure 2–36.
