Modifications for junction box wiringFigure 4-3:
A. Connecting the shield line to the sensor "-" conductor at the sensor end may reduce RF and static
interference. You must isolate sensor shield and "-" conductors from earth ground or the shield
connection at the 6500 side may cause ground loops.
B. Connecting a multi-pair cable overall shield to earth ground at both ends may reduce RF and static
interference. This connection may cause ground loops.
4.2 Wall mount enclosures
The prediction racks are designed to easily mount inside a standard size enclosure.
Emerson offers pre-wired wall mount enclosures for AMS 6500 prediction systems:
Wall mount cabinet System Channels Dimensions Rack size
A6500MS-24-ENCL-IC A6500MS 12 or 24 24”H x 16”W x 12”D 7.5 inch
A6500PRE-SS-WM-24-IC A6500MR 12 or 24 36”H x 24”W x 12”D 19 inch
A6500PRE-SS-WM-48-IC A6500MR 36 or 48 36”H x 24”W x 12”D 19 inch
Note
Install cabinets using guidelines provided by Emerson projects.
• Install at a reasonable height for easy access.
• All cable and conduit piercing should be through the bottom of the cabinet. See Chapter 5.
