Observe polarity!
Note that both batteries should face the
same direction.
•
When the “low battery” indicator appears on the display, both
batteries should be replaced within 90 days.
•
Remove and replace battery #1 rst, then remove and
replace battery #2.
This ensures that all settings and totalizer values are saved.
•
If the low battery symbol reappears for more than 10
seconds after installing new batteries, one battery is
reversed, or battery #2 was installed before battery #1.
•
Secure the batteries by fastening the hook-and-loop straps.

The wiring is identical for the panel mount and the eld mount versions of the totalizer.
•
Only one wire should be inserted into a terminal. Splice double wires outside the terminal.
•
