Setup Configuration Mode
Pressing this button for two seconds toggles between Data Display mode and Setup Configuration mode. Once
inside the Setup Configuration mode, pressing this button selects a parameter for modification. Once selected, the
parameter value blinks while it’s being changed.
If the selected parameter is a numeric value, the cursor is at the right most digit by default. Pressing this button
moves the cursor one position to the left. If the cursor has reached the left most digit, pressing this button again
will save the current numeric value into memory.
Mounting the Meter
The PMC-350-C should be installed in a dry environment with no dust and
kept away from heat, radiation and electrical noise source.
Before installation, make sure that the DIN Rail is already in place
Move the DIN Rail locking clip at the back of the PMC-350-C
downward to the “unlock” position
Align the top of the mounting channel at the back of the PMC-350-C
at an angle against the top of the DIN rail as shown in figure right
Rotate the bottom of the PMC-350-C towards the back while
applying a slight pressure to make sure that the device is completely
and securely fixed on to the DIN Rail
Push the DIN Rail locking clip upward to the “lock” position to secure
the PMC-350-C on to the DIN Rail

RS-485 Wiring
The PMC-350-C provides one standard RS-485 port that supports
the Modbus RTU protocol. Up to 32 devices can be connected on
a RS-485 bus. The overall length of the RS-485 cable connecting
all devices should not exceed 1200m.
If the master station does not have a RS-485 communications
port, a RS-232/RS-485 or USB/RS-485 converter with optically
isolated outputs and surge protection should be used.
LoRaWAN Connection
The DevEUI information can be found on a label underneath the
Front Panel. The AppEUI and AppKey should be pre-configured at
the factory according to the customer’s specification.
