1) Power Requirements
The G3 Conversion Module requires a
12-24VDC voltage source to operate. Any
industrial DC power source that provides
power within the range specified can be
used. When selecting a DC power supply,
ensure that it is capable of providing
enough power for all of the units that it will
be supplying. Each unit requires 3 Watts
of power under maximum load conditions,
and considerably less during normal
operations. Ensure to add capacity if the
power supply will be used for supplying
peripherals such as MODBUS gateways.
2) Remove Terminal Connector
Begin by removing the Terminal Connector
from G3 Conversion Module. This is easily
done by hand or by prying a screwdriver
between it and its mating connector. Make
sure to loosen connector flange securing
screws.

Conversion Module
Ensure the power is turned OFF to prevent
damage to the equipment prior to connecting
the power of circuitry.

CAUTION
3) Connect DC Power Wiring
With the Terminal Connector labeled “6-10”
removed, connect the wires as indicated
in Table D . Secure the wires into place by
using a standard slot screwdriver. For short
local connection (<3 m/10 ft) inside the
low voltage compartment use unshielded
duplex wire such as Belden #8442. For
longer runs use twisted shielded cable such
as Belden #3105 or similar.
