Terminal 8-10:
Connect external switching device between
Terminal 7:
appropriate User Input terminal and User Comm.
In this logic, the user inputs of the
meter are internally pulled up to +5 V
with 22 K resistance. The input is active
when it is pulled low (<0 .9 V).

In this logic, the user inputs of the meter are
internally pulled down to 0 V with 22 K
resistance. The input is active when a voltage
greater than 3.6 VDC is applied.
