V. Wiring Diagrams
There are several key application considerations and system specifications (bottom of drawing) when
using these components (conversion module, cable and input module). Read and understand these
considerations before installation.

Conversion Module Installation and Application Considerations
 This Bul. 1492 cable consists of a cable wired to one 1756-IF16 RTB. Recommended cable lengths of 0.5M or 1.0M (005=0.5M, 010=1.0M).
See table 2 for other lengths.
 SHIELD GROUNDING: In some installations, the field wiring shield was grounded on the 1771 chassis. If this was the case, the installer must
remove these shield connections from the 1771 chassis and they can be connected to the grounding stud on the 1492-CM1771-LA001 module.
The pre-wired cable used between the 1492-CM1771-LA001 module and the 1756-IF16 [1492-CONACAB005B] provides a shield ground lug to
ground the shield at the 1756 ControlLogix chassis, this must be connected. Do NOT connect this ground lug to the conversion module grounding
stud.
 This design assumes that all inputs on the 1771-IFF were connected to current transmitters. If there was a mix of current and voltage
transmitters, then modification of the pre-wired cable [1492-CONACAB005B] will need to occur at the 1756-IF16 terminal block. Refer to the
1756-IF16 Installation Manual for modification details.
 The 1771-IFF analog input ranges were configured via software, as is the input range for the 1756-IF16. Please ensure the correct input range
is configured in the 1756-IF16.
 Refer to your 1771-IFF and 1756-IF16 Installation and User Manuals for additional information concerning comparisons of module wiring,
features and configuration details. [Reference Doc: 41171-023 (Version 00)]
