4532	Wiring

Note! The 4590 TSM has three sets of i.s. HART terminals. These three pairs are looped internally.

Caution! Do not connect signal HART lines from the 4532 ATC to terminals 30 and 31. They are designed to supply drive power for the 7500 Series Radar Tank Gauge only.

6.2Grounding

The 4532 ATC must be grounded to the tank potential before communication and power connections are made. The connections from ground terminal of the 4532 ATC to the tank ground must be made before any other wiring connections are made. All grounding must be compliant with local and company regulations and checked before the equipment is commissioned.
