NOTICE
NOTICE
The THUM and all other wireless devices should be installed only after the Smart Wireless
Gateway has been installed and is functioning properly. Wireless devices should also be
powered up in order of proximity from the Smart Wireless Gateway, beginning with the
closest. This will result in a simpler and faster network installation.
During normal operation, or in fault condition, the THUM will cause a 2.5 V drop in the
connected loop. It is important to ensure that the power supply can provide at least 2.5 V
more than the lift off voltage of the wired device to make sure it works properly with the
THUM installed. To determine the lift off voltage for the wired device, review the wired
device operation and installation manual.

Smart Wireless THUM Adapter
CONSIDERATIONS
General The Smart Wireless THUM Adapter is connected to a HART sub-device. With
simple HART configuration, the THUM transmits the HART information from
the sub-device into the Wireless network.
Commissioning The THUM can be commissioned before or after installation. It may be useful
to bench commission the THUM before installation to ensure proper op eration
and to become familiar with the functionality. The instruments should be
installed in accordance with intrinsically safe or non-incendive field wiring
practices, when required. The THUM Adapter is powered when connected to
a powered loop.
Mechanical When choosing an installation location and position for the transmitter, take
into account access to the device. For best performance, the antenna should
be vertical and have some space between objects in a parallel metal plane
such as a pipe or metal framework, as the pipes or framework m ay adve rsely
affect the performance of the antenna.
Electrical The THUM Adapter is connected into a powered 4–20 mA loop, powering
itself by scavenging power . The THUM Adapter causes a vo ltage drop across
the loop. The drop is linear from 2.25 volts at 3.5 mA to 1.2 volt s at 25 mA, but
does not effect the 4–20 mA signal on the loop. Under fault conditions, the
maximum voltage drop is 2.5 volts.
Environmental Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations certifications.

Wireless Considerations Power Up Sequence
Power should not be applied to any wireless device until the Smart Wireless
Gateway (“Gateway”) is installed and functioning properly. Wireless devices
should also be powered up in order of proximity from the Gateway, beginning
with the closest. This will result in a simpler and faster network installation.
Enable Active Advertising on the Gateway to ensure that new devices join the
network faster. For more information see the Smart Wireless Gateway Manual
(Doc. No. 00809-0200-4420).
THUM Adapter Position
If possible, the THUM Adapter should be positioned vertically, either straight
up or straight down, and it should be approximately 3 ft. (1 m) from any large
structure, building, or conductive surface to allow for clear communication to
other devices. If the THUM Adapter is mounted horizontally, wireless
communication range may be decreased.

Smart Wireless THUM Adapter
Figure 1-1. THUM Adapter
Position
Conduit Entry
When installing the THUM Adapter into the conduit entry of a wired device,
use an approved thread sealant. Thread sealant provides a water tight se al.
The thread sealant also provides a lubrication to ensure easy removal of the
THUM Adapter.
Reference Manual
00809-0100-4075, Rev BA
October 2010
M20 Conduit Adapter
When using the M20 Conduit Adapter on the THUM Adapter, use an
approved thread sealant and tighten wrench tight to the THUM Adapter. When
installing the M20 conduit adapter into a condu it tighten to 3 2.5 Nm/25 ft -lb. to
ensure water tight seal.
Field Communicator Connections
In order for the Field Communicator to interface with the THUM Adapter, the
wired device must be powered. The Field Communicator must be put into poll
mode and should use the THUM Adapter address of 63.
Power Supply
Minimum loop load of 250 Ohms.
The THUM Adapter communicates and derives power from a standard 4-20
mA/HART loop. The THUM Adapter causes a small voltage drop on the loop
which is linear from 2.25 V at 3.5 mA to 1.2 V at 25 mA. Under fault
conditions, the maximum voltage drop is 2.5 V. The THUM Adapter will not
affect the 4-20 mA signal under normal or fault conditions as long as the loop
has at least a 2.5 V margin at the maximum loop current (25 mA for a typical
4-20 mA/HART device).
Limit the power supply to 0.5 Amps maximum, and voltage to 55 Vdc.

Load Resistor
If required, add a load resistor as shown in Figure 3-20, 3-22, and 3-24. The
resistor should be adequately rated for the application (1W minimum) and be
compatible with the supplied splice connector which accepts wire sizes from
14 to 22 AWG.
When adding a load resistor, ensure that uninsulated conductors do not
contact the enclosure and/or other exposed m etal parts.
