These are the variants with 32 A or 2 A relays: SGM3013, SGM3022, SGM3023, SGM3033, and
SGM30C2.
For SGM3013, SGM3022, SGM3023, and SGM3033 meters, the load control functionality will
function independently for the 32 A relay and the 2 A relay.
For the SGM30C2 meter, the load control functionality will function for one of the 2 A relays.
The configuration parameters for each relay in the meter providing the auxiliary load control
functionality will be stored independently in NVRAM. All configuration options for the load
control relays will be configurable locally via MeterMate and remotely via the AMI interface. All
configuration options for the load control relays will be configurable remotely via the AMI
interface.

•
Condition 1: The load control relay must be installed in the meter.
•

•
Condition 3: The LCD is configured to display the load control relay state.
