5.  Wire Power Meter to 

Gateway Adapter

Wire ports 11,12, and 13 on the power meter to the gateway adapter, and plug it 
into the gateway.  Use 22/3 or 22/4 shielded wire. 

1.  Connect port 11 (A) on the power meter to A on the gateway adapter.

2.  Connect port 12 (B) on the power meter to B- on the adapter.

3.  Connect port 13 (G) on the power meter to GND on the adapter.

Connect the gateway to power with the 120V AC wall adapter, or with the direct 
12V-48V DC adapter. 

Once the meter is properly mounted to the DIN Rail or enclosure, all wiring is 
completed, and terminal block covers are installed, power can be turned back 
on. 

With power back on, the gateway will automatically connect to the cloud via 
its cellular connection and update to the latest software. The LED indicates the 
gateway status. Confirm that the gateway LED turns green.

6.  Connect Gateway 

to Power
