The total worst case current is calculated as follows:
ANN-80 Current Draw
ANN-S/PG Current Draw
ANN-I/O Current Draw
Total Worst Case Current Draw
Using this value and referring to the Wiring Distance Table 1.1 on page 24, it can be found that the
available options are:
•
463 feet maximum using 22 Gauge wire
•
1,172 feet maximum using 18 Gauge wire
•
1,866 feet maximum using 16 Gauge wire
•
2,953 feet maximum using 14 Gauge wire
