Repeat step 3 for the remaining mounting screws.
5.
Securely tighten all eight mounting screws to keep out external environmental
elements.

Reinstall field wiring and cable connections to the new µFLO
board. Use Figure 3 for component and terminal locations and the information in
Table 2 to determine if the connector requires rewiring to a new terminal.
WARNING – Bodily injury and property damage. Wiring peripheral
