ATTENTION
Remove power from the 1771 I/O chassis backplane
before you install the module. Failure to remove
power from the backplane could cause:
•
module damage or degradation of performance
•
injury or equipment damage due to possible
unexpected operation
Place the module in the card guides on the top and bottom of the chassis
that guide the module into position.
Important: Apply firm even pressure on the module to seat it into its
backplane connector.

Snap the chassis latch over the
top of the module to secure it.
Swing the chassis locking bar
down into place to secure the
modules. Make sure the locking

WARNING
When you insert or remove the module while
backplane power is on, or you connect or
disconnect the wiring arm with field power
applied, an electrical arc can occur. This could
cause an explosion in hazardous location
installations. Be sure power is removed or the area
is nonhazardous before proceeding.
The 1771–IAD module is a modular component of the 1771 I/O
system requiring a properly installed system chassis. Refer to
publication 1771–IN075 for detailed information on acceptable
chassis, proper installation and grounding requirements. Limit the
maximum adjacent slot power dissipation to 17W maximum.
