2.1.1 MOUNTING LOCATION CONSIDERATIONS
Select the mounting location with care. Certain mounting configurations can hinder or even
completely block wireless signal transmission, or can introduce electrical noise to the signal.
Common mounting mistakes include the following:
Shipping container blocks signal
FIGURE 3: Mounting Considerations
Large structures, such as walls, buildings, etc. can block and/or reflect RF signals. Tips include:

2.1.2 GROUND THE SUPERVISOR AND NODES
Install a grounding rod and cable, or other suitable ground, at a location near each device.
Cellular Gateway Supervisors and Multi-Channel Nodes come equipped with a copper
grounding lug to which you can connect the grounding cable. Ground non-cellular Supervisors
and Nodes by connecting the grounding cable to the mounting bracket.
Don't reinstall the Node covers until after you have connected all the necessary sensor cables.

Nodes
Mount antennas above metallic structures.
Keep in mind that nodes communicate with each other, not just with the supervisor.
A high Received Signal Strength Indicator (RSSI) level does not guarantee trouble-free
communication.
Mount devices such that their antennas are on top, pointing upward.
Loosen the nut on the cable fitting and remove the white plastic dowel.
Slide the transducer cable through the cable gland nut and fitting.
Insert the lead wires into the terminal block as shown in Figure 5 and Table 3. Press on the
orange tab, insert the bare end of the wire into the terminal block, and then release the tab.
Pull gently on each conductor to ensure it is secure.
Tighten the cable gland nut until it firmly grips the outer jacket of the cable. The cable gland
nut must be properly tightened to prevent water entry. Do not over-tighten, as this might
strip the plastic threads.
Pull gently on the gauge cable to ensure it is held in place by the cable gland.
Repeat these steps for each gauge cable you need to connect.
