Attaching Cables
1. Disconnect power
2. Check bus lever position.
Left cover: Make sure the bus lever (4) on the left-most I/O module is in the
unlocked (fully right) position.
Right cover: Make sure the bus lever (4) on the right cover is in the unlocked
(fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the cable
cover to the module.
4. Move the cable cover back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
TIP
•
A maximum of two expansion cables may be used in a 1769
system.
•
Each I/O bank requires its own power supply. The 1769 cables
extend the 1769 communication bus, but do not extend bus
power.
