3. Choose a physical path for the sensor cable pull according to the following
guidelines:
• Follow plant standards for segregating instrumentation, communication, and
power cable runs.
• Do not pull cable across machinery maintenance access areas such as guards,
shields, and access panels.
• Do not pull cable in machinery control/starting cable trays.
• Do not run any cable on the floor.
• Do not run cable near pathways where it will be exposed to damage from moving
machinery.
4. Starting at the sensor housing, use cable tie-downs to secure cable at 2 ft intervals
to machinery and plant infrastructure.
5. At junction/switch boxes, pull the cable through an existing PGME07 cord grip.
• Tighten the cord grip with 9/16 in. wrench until cable is secure. Do not
overtighten.
• Blunt cut the cable, leaving approximately 2 ft inside the box. Relabel the wire if
necessary.
• If you are using armored cable, remove the armor before pulling the cable
through the cord grip; cut the end of the armor with wire cutters and unravel the
length to remove. Use a heat shrink to seal the end of the armor.
5.3 Pull cable from the junction box to the unit
Use the cables in Section 5.3.1 to extend the online instrumentation wiring from the
junction boxes to the unit enclosure.
Procedure
1. Starting at the junction box, pull the cable through the conduit run.
2. At the unit enclosure, blunt cut the cable, leaving enough cable inside the enclosure
for routing to terminal connectors.
3. Label wire according to project specifications and place the label within 6 in. of the
cable access plate, with the label facing the front of the enclosure.
4. At the junction box, blunt cut the cable, leaving 2 ft inside the box for routing.
5.3.1 Recommendations for junction box-to-unit cables
Note
For cables with overall braided shield, ground the shield to the AMS 6500 enclosure.
