– The IP20 degree of protection (EN 60529) of the device is intended for a
clean and dry environment.
– Do not subject the device to any load that exceeds the prescribed limits.
– Only passive antennas may be installed on the devices.
– The device is not designed for use in environments with danger of dust ex-
plosions.
Power supply of the device must comply with the suitable requirements:
– Class 2 circuit according to National Electrical Code, NFPA-70 and Canadian Electrical
Code, Part 1, C22.1
– Limited Power Supply (LPS) according to EN/IEC 60950-1 or EN/IEC 62368-1
– Limited-energy circuit according to EN/IEC 61010-1
Connect a regulated power source to the transceiver. The supply voltage can range from 10.8
to 30 VDC with a nominal voltage of either 12 VDC or 24 VDC is recommended. The power
supply must be able to supply 130 mA of current at 24 VDC.

5.2.2 Ethernet connections
Connect a CAT5 Ethernet cable between the port on the AWIN GW120 and the network
adapter card on your computer. Use either a crossover (C/O) or 1:1 cable as the radio has au-
tocross functionality. The cable should not exceed 100 m (329 ft.) in length. Alternatively, an
Ethernet switch can be used for connection.
5.2.3 Antenna connections
There is one antenna connector on the AWIN GW120 (see Figure 4 ). A single antenna is used
for the WirelessHART mesh network.
Observe the maximum RF power allowed in your country. Only use antennas
and cables recommended by ABB.
