2.6 Grounding
The flow computer includes a ground stud on the bottom of the battery compartment
Figure 2-7. Ground Stud
▪ Once you have installed the unit, run a ground wire between the ground stud on the
bottom of the battery compartment and a known good earth ground. You route the
ground wire through one of the conduit fittings.
▪ Use stranded copper wire to earth ground and keep the length as short as possible.
▪ Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).
▪ Using a high-wattage soldering iron, tin the wire ends with solder before you insert
them into the chassis ground lug.
▪ Run the ground wire so that any routing bend in the cable has a minimum radius of
30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
For more information on grounding or if your installation uses cathodic protection, refer to Site
Considerations for Equipment Installation, Grounding, and Wiring (D301452X012).
2.7 Opening/Closing the Enclosure
The enclosure opens/closes differently depending upon whether you have the fiberglass enclosure
or the aluminum enclosure.

Fiberglass Enclosure
The enclosure includes two fasteners at the top and bottom of the door. To open the door,
lift the clasp to loosen the latch and pull it free of the post, then repeat for the other fastener
and open the door. To fasten the door, place the latch on the post and press down the clasp;
repeat for the other fastener.
