ATTENTION
Remove power from the 1771 I/O chassis
backplane and field wiring arm before removing
or installing an I/O module.
•
Failure to remove power from the backplane or
wiring arm could cause module damage,
degradation of performance, or injury.
•
Failure to remove power from the backplane
could cause injury or equipment damage due to
possible unexpected operation.
!
ATTENTION
A module inserted into a wrong slot could be
damaged by improper voltages connected through
the wiring arm. Use keying bands to prevent
damage to the module.
Place your module in any slot in the chassis
except the leftmost slot, which is reserved for
processors or adapters.
Observe the following precautions
when inserting or removing keys:
•
insert or remove keys with your
fingers
•
make sure that key placement is
correct
Incorrect keying or the use of a tool
can result in damage to the
backplane connector and possible
system faults.
!
ATTENTION
Position the keying bands in the backplane connectors to correspond to
the key slots on the module.
You can change the position of these bands if
subsequent system design and rewiring makes
insertion of a different type of module necessary.
