1 Wireless considerations
1.1 Power up sequence
The power module should not be installed on any wireless device until the
Emerson 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
Wireless Gateway Reference Manual.
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 Wireless THUM Adapter Reference Manual 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.

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 watertight seal.
