IX20 power supply requirements
IX20 is intended to be powered by a certified power supply with output rated at either 12 VDC/0.75 A
or 24 VDC/0.375 A minimum.
n
Use the included power supply (part number 24000154).
n
If you are providing the DCpower source with a non-Digi power supply, you must use a
certified LPS power supply rated at either 12 VDC/0.75 A or 24 VDC/0.375 A minimum. The
voltage tolerance supports +/- 10% (9 VDCto 30 VDC) at 9 Watts minimum.
n
For installations requiring protective earth grounding, connect the -ve terminal of the power
connector to the system protective earth with a minimum 1mm2 stranded single insulated
cable. Crimp terminals should be used for all connections.

Configuration for extreme thermal conditions
The IX20 has been verified to operate in the following temperate ranges:
IX20W(Wi-Fi enabled version): -20Cto +70C/-4F to +158F.
n
IX20 (non-Wi-Fi version): -40Cto +70C/-40F to +158F.
n
However, in extreme temperature conditions (up to +70C/+158F), you must add a Quality of Service
(QOS) rule that limits the upload speed of the modem to 1 Mpbs. For less extreme temperatures, a
modem upload speed of up to 10 Mpbs is acceptable.
