
Allow some slack in the wire while making terminal connections. Slack makes the
wires more manageable and helps minimize mechanical strain on the terminal
blocks.

Use twisted pair, shielded and insulated cable for communication and I/O wiring to
minimize signal errors caused by electromagnetic interference (EMI), radio
frequency interference (RFI), and transients. When using shielded cable, ground all
shields at only one point in the appropriate system. This prevents circulating ground
current loops that can cause signal errors.
2.6 Front or Rear End Caps
The flow computer includes two threaded covers (end caps). The front end cap includes a
window for viewing the HMI module; the rear end cap provides access to the terminal
plate for power and I/O wiring.
2.6.1 Removing/Replacing Retaining Clamp on End Caps
For flameproof ATEX/IEC applications, each end cap includes a retaining clamp which
screws down to prevent the end cap from being unscrewed.
