* Please note: The RS485 (officially called TIA/EIA-485-A) connection between
your IGW/922 and the field devices needs termination resistors on both ends for
proper operation. The IGW/922 does not offer internal termination resistors. Please
make sure, that the RS485 cable connection is equipped with external termination re-
sistors.

4.2 Power Supply
The Remote Access Gateway IGW/922 needs a supply voltage of 11 .. 28 VDC to work. Use
the power adapter cable to provide the system with the necessary power like shown in the
figure below.

CAUTION: Providing the Remote Access Gateway IGW/922 with a higher voltage than the
regular 11 .. 28 VDC could cause damaged board components!
CAUTION: Do NOT turn on the power supply while connecting the power adapter cable
with the Remote Access Gateway IGW/922. This could cause damaged board components!
First connect the power adapter cable and THEN turn the power supply on.
