4 Installing Your Sure Cross
®
Radios
Follow these recommendations to install your wireless network components.
4.1 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.
4.1.1 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.
3
Seal any unused PG-7 access holes with one of the supplied black plastic plugs. To install a watertight PG-7 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.
Seal the 1/2-inch or 3/4-inch NPT port(s) if it is not used. To 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 Sure Cross unit. These threads are tapered and will
create a waterproof seal without over-tightening.
3 This is not a lot of torque and 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.
