Installation 

To install the module and field wiring arm, follow this procedure：

1. Place the module in the card guides on the top and bottom of the chassis that guide the module into position, noting the following:

• For a 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B I/O chassis, snap the chassis latch over the top of the module to secure it.

• For a 1771-A1B, 1771-A2B, 1771-A4B I/O chassis, swing the chassis locking bar down into place to secure the modules, making sure the locking pins engage. 

2. Attach the 1771-WN wiring arm to the horizontal bar at the bottom of the I/O chassis noting the wiring arm pivots upward and connects with the module so you can install or remove the module without disconnecting the wires.
