Mounting SureCross Devices Outdoors
Use a Secondary Enclosure. For most outdoor applications, we recommend installing your SureCross devices inside a secondary
enclosure. For a list of available enclosures, refer to the
Accessories
list.
Point Away From Direct Sunlight. When you are not using a secondary enclosure,
minimize the damaging effects of ultra-violet radiation by mounting the devices to
avoid facing intense direct sunlight.
•
Mount under an overhang or other source of shade,
•
Install indoors, or
•
Face the devices north when installing outside.
For harsh outdoor applications, consider installing your radio inside a secondary
enclosure. For a list of available enclosures, refer to the
Accessories
list.
Mount Vertically to Avoid Collecting Rain. When possible, mount the devices where rain or snow will drain away from the device.
•
Mount vertically so that precipitation, dust, and dirt do not accumulate on permeable surfaces.
•
Avoid mounting the devices on flat or concave surfaces, especially if the display will be pointing up.
Remove Moisture and Condensation. If condensation is present in any device, add a
small desiccant packet to the inside of the radio. To help vent the radios, Banner also
sells a vented plug (model number BWA-HW-031) for the 1/2-inch NPT port of the
SureCross radios.
Watertight Glands and NPT Ports
To make glands and plugs watertight, use PTFE tape and follow these steps.
1. Wrap four to eight passes of polytetrafluoroethylene (PTFE) tape around the threads
as close as possible to the hexagonal body of the gland.
2. Manually thread the gland into the housing hole. Never apply more than 5 in-lbf of
torque to the gland or its cable clamp nut.

Seal any unused access holes with one of the supplied plastic plugs. To install a watertight plug:
1. Wrap four to eight passes of PTFE tape around the plug’s threads, as close as possible to the flanged surface.
2. Carefully thread the plastic plug into the vacant hole in the housing and tighten using a slotting screwdriver. Never apply
more than 10 in-lbf torque to the plastic plug.
If your device has an unused NPT port, install a watertight NPT plug:
1. Wrap 12 to 16 passes of PTFE tape evenly across the length of the threads.
2. Manually thread the plug into the housing port until reaching some resistance.
3. Using a crescent wrench, turn the plug until all the plug’s threads are engaged by the housing port or until the resistance
doubles. Do not over-tighten as this will damage the device. These threads are tapered and will create a waterproof seal
without over-tightening.

This is equivalent to the torque generated without using tools. If a wrench is used, apply only very light pressure. Torquing these fittings excessively
damages the device.
