The best way to mount a FieldPoint system is on a single 35 mm DIN rail inside an instrumentation cabinet. Do not mount the FieldPoint system on a door or panel. Doors can contort and bend DIN rails, causing disconnections. Panel mounting can cause FieldPoint modules not to make solid contact with each other.

Note If you need more than one length of DIN rail, use up to two FieldPoint Bus Extender cables instead of splicing DIN rails together. You can order FieldPoint Bus Extender cables from NI. You must install DIN rail locks at each end of the bank to ensure reliable connections between terminal bases and network module.

Grounding and Shielding the FieldPoint System Protecting the FieldPoint System from Damage In order to comply with EMC specifications, the FieldPoint system must be mounted inside a metal enclosure such as the FP-ENC1. For maximum protection from electromagnetic interference and electrostatic discharge, ground the enclosure as shown.

Do not use a cable longer than 100 m. If you are using a 100 Mbps Ethernet, National Instruments recommends using a Category 5 shielded twisted-pair cable. If you need to build your own cable, refer to the FP-20xx User Manual specifications section for cabling details.
