power range. The power cable is removable and is available in the power type
specific to your location. The 9160 G2 AC power supply has a universal input via a
standard IEC320 connector.

To eliminate the need for AC wiring, the 9160 G2 Wireless Gateway is compliant
with IEEE 802.3af and can be powered over its Ethernet connection. For detailed
information, please see “Power Over Ethernet Requirements” on page 262.

Warning:

To avoid electric shock, the power cord protective grounding
conductor must always be connected to ground.

2.1.4.2 Antennas

The type of antenna required for each installation depends on the coverage require-
ments and the frequencies used. A maximum of four antenna elements can be used.
These antennas can be a combination of reverse thread SMA “screw-on” diversity
or high-gain WDS antennas. There are several omnidirectional antennas and special,
directional antennas available from Psion Teklogix. Generally, a site survey deter-
mines the appropriate antenna. Consult Psion Teklogix service personnel for more
information.

Warning:

Never operate the 9160 G2 without a suitable antenna or a
dummy load.

Connection To Outdoor Antenna (Kit P/N 1916641)

The antenna must be installed by a qualified service person and installed
according to local electrical installation codes. The antenna should be located
such that it is always at least 15 ft (4.6 m) high and 10 ft (3 m) from the user and
other people working in the area.

For a 9160 G2 connecting to an outdoor antenna, all the following notes are applica-
ble:

1.

The shield of the outdoor antenna coaxial cable is to be connected to
earth (independent of the 9160 G2) in the building installation, pro-
vided the installation is acceptable to the authorities in the country of
usage.

2.

A supplementary equipment earthing conductor is to be installed
between the 9160 G2 and earth—that is, in addition to the equipment
earthing conductor in the power supply cord.
