Wireless Considerations - Emerson Smart Wireless THUM Quick Start Manual

1.0 Wireless considerations

1.1 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 (document
number 00809-0200-4420).
1.2 THUM Adapter position
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 (document number 00809-0100-4075) for more
information.

1.3 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.
1.4 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 N-m/25 ft-lb to ensure
water tight seal.
