2.2.4 Grounding the Field Link

Revised June-2018

Figure 2-3. Field Link Mounting

For further information on grounding the field link, refer to the

documentation that accompanied the device (Emerson™ Wireless 781

Field Link Quick Installation Guide, part 00825-0100-4421)

This section assumes you have already successfully installed the IEC

62591 module in either a ROC800 or a FB107 and installed the Field

Link in its permanent field location.

Communications between the IEC 62591 module and the Field Link

occur through an RS-485 connection. Remote Automation Solutions

recommends that you use shielded, twisted-pair cable for I/O signal

wiring. The twisted-pair minimizes signal errors caused by electro-

magnetic interference (EMI), Radio Frequency Interference (RFI), and

transients. The removable terminal blocks on the module accept wire

sizes 16 to 22 AWG.

: Ensure that wiring between the ROC800 or FB107 IEC 62591

Note

module and the Field Link meets all appropriate local

requirements (use of conduit, etc.).

Power down the IEC 62591 module (if it is currently powered).

Remove the housing cover identified on the casing as "Field

Terminals."
