Installation
Watertight Glands and Plugs
If the Gateway or Node is mounted outdoors or will be exposed to
moisture, dirt, or dust, follow these steps to weatherproof the units.
Watertight Glands
To make the glands watertight:
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.*
Note, these instructions apply both to the PG-7 glands and the 1/2”
NPT gland.
Weather-Proofing Glands and Plugs
Rotary Switch Access Cover
Check the rotary switch access cover o-ring every time the access
cover is removed. Replace the o-ring when it is damaged, discolored,
or showing signs of wear. The o-ring should be:
• Seated firmly against the threads without stretching to fit or
without bulging loosely, and
• Pushed against the flanged cover.
When removing or closing the rotary switch access cover, manually
twist the cover into position. Do not allow cross-threading between
the cover and the DX80 face.
Once the cover is in place and manually tightened, use a small
screwdriver (no longer than five inches total length) as a lever to
apply enough torque to bring the rotary switch access cover even
with the DX80 cover surface.
Watertight 1/2” NPT Plug
Seal the 1/2” NPT port 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 9/16” crescent wrench, turn the plug until all the
plug’s threads are engaged by the housing port or until the
resistance doubles. Do not overtighten as this will damage
the SureCross unit. These threads are tapered and will
create a waterproof seal without overtightening.
Watertight PG-7 Plug
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
DX80 housing and tighten using a slotting screwdriver.
Never apply more than 10 in-lbf torque to the plastic plug.
* 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.
