2.5 Connecting the Power Wires

The EMC-1 is powered from an 8-80 Vdc supply, such
as an AC-DC converter or system battery connected
to the power input provided on the EMC-1 unit. See
the Operation section (3) for details on the start-up
procedure. Connect the power wires as indicated in
Figure 2-4 below.
NOTE: The EMC-1 will start up with
an RJ-11 connection to a powered
Morningstar Device, or with direct
power to the EMC-1
Figure 2-4. Connecting the power wires
NOTE: Although the Morningstar Device will provide
power to the EMC-1 through the Meterbus port, it may
not be sufficient under all operating conditions. The
8-80V power supply is required as a constant, reliable
power source.

3.2 Start-up

After the EMC-1 has been installed, as described in
Section 2.3.1, the unit is started by connecting the
power supply, as described in section 2.5.
On start-up, the status LED will flash green once,
and then all LEDs [green, green, (green)] will light
simultaneously for three seconds. Next, the EMC-1
will automatically begin searching for valid Morningstar
Devices. If equipped, the Morningstar Device must have
its MODBUS DIP switch enabled for the connection to be
made.
