Output Connections

The meter's pulse and counter outputs report total real energy consumed. For dual-
element meters, this is a combined total for Line 1 and Line 2. The 10 Wh isolated
output is typically used for meter verification and calibration. The 100 Wh and 1000
Wh isolated outputs are intended for automatic meter reading (AMR) systems. There
are two terminals for mechanical counter connection. There is no polarity associated
with the terminals. V
Output connections are listed in Table 4.

For 12 VDC electro-mechanical counter
(not isolated). There is no polarity associated
with the two wires of the counter - either wire
can be connected to the + (pulse) output.
