Installing the Linear Positioning Module

Chapter 5

55

A package of plastic keys (Cat. No. 1771-RK) is provided with every I/O

chassis. When properly installed, these keys prevent the seating of anything but

the module in the keyed I/O chassis slot. Keys also help to align the module

with the backplane connector.

Each module is slotted at its rear edge. Position the keys on the chassis

backplane connector, corresponding to the slots on the module’s rear edge.

Insert the keys into the upper backplane connectors. Position the keys between

the numbers at the right of the connectors, as shown in Figure 5.3.

After setting analog output switches and setting the keying positions, you’re

ready to insert the module into a slot in the I/O chassis.

To insert the module, follow this procedure:

1. Remove all power from the I/O chassis and from the module’s wiring arm

before inserting or removing a module.
