Chapter 4 Install the Module
Wire Modules
Follow these guidelines when wiring the modules.
• Do not route communication, input, or output wiring with conduit
containing high voltage. Refer to the Industrial Automation Wiring and
Grounding Guidelines, publication 1770-4.1
.
• Wire correctly after confirming the signal names of all terminals.
• Use shielded cable for analog and tachometer inputs.
• When using the sensor power supply on the 1734-IE4S module, do not
connect an external power supply to the sensor.
• If you use the 1734-IE4S module's sensor power supply to power your
input devices, you are responsible for verifying that your application
operates properly with the diagnostic features of this output.
• Tighten screws for communication and I/O connectors correctly.
• When using analog inputs, wire only to voltage or only to current inputs,
not both. Mixing input types may induce noise on the input
measurements.
ATTENTION: Wire the POINT Guard I/O modules properly so that 24V DC line
does not touch the safety outputs accidentally or unintentionally.
Do not connect loads beyond the rated value to safety outputs.
Wire conductors correctly and verify operation of the module before placing the
system into operation. Incorrect wiring may lead to loss of safety function.
Do not apply DC voltages exceeding the rated voltages to the module.
Do not connect a power source to the sensor power supply in the 1734-IE4S
module or you could blow an internal fuse, rendering the module inoperative.
Disconnect the module from the power supply before wiring. Devices connected to
the module may operate unexpectedly if wiring is performed while power is
supplied.
WARNING: If you connect or disconnect wiring while the field-side 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.
This equipment shall be used within its specified ratings defined by Rockwell
Automation.
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
