Wireless considerations
Power-up sequence
The Wireless Gateway should be installed and functioning properly before any wireless devices are powered.
Battery is already installed in the Location Anchor. Move power switch to "ON" position to power up. This
results in a simpler and faster network configuration. Enabling Active Advertising on the Gateway ensures
new devices are able to join the network faster. For more information, see the Wireless Gateway Reference
Manual.
Antenna position
The antenna is internal to the Location Anchor. To achieve optimal range and performance, position the
Location Anchor with the stem in a horizontal position as shown in Figure 4-1 . Good connectivity can also be
achieved in other orientations. The antenna should also be approximately 1 m (3 ft.) from any large structure,
building, or conductive surface, and a minimum of 2 m (6 ft.) and maximum of 4 m (13 ft.) from the ground to
allow for clear communication to other devices. Refer to best practices for additional information on optimal
mounting locations of the Location Anchor.

Electrical
Battery
The Emerson Location Anchor is self-powered. The battery is a single “D” size primary lithium/thionyl chloride battery.
Each battery contains approximately 5.0 grams of lithium. Under normal conditions, the battery materials are self-
contained and are not reactive as long as the battery is maintained. Care should be taken to prevent thermal, electrical,
or mechanical damage. Contacts should be protected to prevent premature discharge. Battery cannot be changed
in a hazardous location.

Installation considerations
Procedure
1.
Inspect mounting bands periodically and re-tighten if necessary. Some loosening may occur after
initial installation due to thermal expansion/contraction.
2.
The stainless steel mounting bands could be affected by stress corrosion and potentially fail when
in the presence of chlorides.
3.
The Location Anchor should be installed such that steam or other high temperature fluids do not
directly impinge the housing of the Location Anchor.
4.
Good connectivity can also be achieved in other orientations. The antenna should also be
approximately 1 m (3 ft.) from any large structure, building, or conductive surface, and a minimum of
2m (6 ft.) and a max of 4m (13 ft.) from the ground to allow for clear communication to other devices.
4.6
Mounting
Procedure
1.
Locate the Location Anchor on a vertical or horizontal structure. Align the Location Anchor as shown in
Figure 4-1 .
2.
Tighten clamp to 10.2 N-m (90 in-lb).
3.
If commissioning the Location Anchor, remove the electronics cover, move the power switch to the on
position.
4.
Ensure the cover is fully tightened to prevent moisture ingress. The lip of the polymer electronics cover
should be in contact with the surface of the polymer enclosure to ensure a proper seal. Do not
overtighten.
