Make wiring connections to the module through the field wiring arm
(cat. no. 1771-WN). The arm pivots on the I/O chassis to connect
with terminals on the front of the module and acts as a terminal strip.
The wiring arm allows the module to be removed from the chassis
without disconnecting wiring.
!
WARNING
When you connect or disconnect the field wiring
arm with field power applied, or remove the
module while backplane power is on, an electrical
arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is
nonhazardous before proceeding.
!
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.
1. Make certain all power is removed from the module before
making wiring connections.
2. Swing the wiring arm up into position on the front of the module.
The locking tab on the module will secure it into place.
3. Make your connections to the field wiring arm as shown in the
connection diagram. (Use the label on the front of the wiring arm
to identify your wiring.)
IMPORTANT
The field wiring arm terminal identification
number is not the same as the number of the bit
which controls that output.
