W IRELESS C ONSIDERATIONS
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 straight up, and 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. The THUM Adapter should not be mounted
vertically straight down. See THUM Adapter reference manual (00809-0100-4075) for more
information.
Figure 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 seal. The thread sealant also provides
lubrication to ensure easy removal of the THUM Adapter.
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 conduit, tighten to 32.5 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.
