When using shielded cable, ground the foil shield and drain wire only at one
end of the cable. We recommend that you wrap the foil shield and drain wire
together and connect them to a chassis mounting bolt (Figure 3.3). At the
opposite end of the cable, tape exposed shield and drain wire with electrical tape
to insulate it from electrical contact.

Refer to Wiring and Grounding Guidelines, publication 1770-4.1 for additional information.
When installing your module in an I/O chassis:
1. First, turn off power to the I/O chassis:
WARNING: Remove power from the 1771 I/O chassis backplane
and wiring arm before removing or installing an I/O module.
Failure to remove power from the backplane could cause injury or
equipment damage due to possible unexpected operation.
Failure to remove power from the backplane or wiring arm could
cause module damage, degradation of performance, or injury.
