Appendix E: Important Outdoor Install Guide
This EZBridge unit requires additional grounding and protection prior to installation to ensure trouble free operation
and warranty compliance. Please follow the process below to ensure you are protected against flash memory
corruption, premature hardware failure, and/or earth-ground potential issues.
Cause and Effect
It has been recently discovered that by simply grounding the NEMA4 enclosure containing the EZBridge PCB,
operation with unstable power and un-filtered AC lines can be made more reliable and not cause damage to the circuit.
(Most customers have circuits shared with electric motors, solenoids, fluorescent lighting, and/or dimmers,
transformers, etc. These devices compromise the neutral when there is no earth-ground available.) Many field-tested
units have been damaged by inadequate grounding at the installation site as well as voltage spikes on the neutral side
of the AC line, resulting in corrupted flash memory and ultimately an un-recoverable error condition. To prevent this
from impacting your EZBridge and to maintain your Teletronics’ warranty, you must follow the simple process set forth
below prior to initial power-up.
Tools and Materials Required:
1. #2 Philips Screwdriver
2. Teletronics’ supplied grounding wire, screw, washer, and lockwasher.
*Customer can use their own cable if desired; however the potential must not be more than 2-Ohms of resistance from
enclosure to ground-point.
Procedure:
1. Carefully place the EZBridge face down on a solid work surface, with mounting holes pointing up.
2. Insert self-threading screw into the detent 1.65” (42mm) from top of bridge and 1.00” (25.5mm)
3. from the side. (Please use picture as reference.) The diameter of the screw hole should be 0.15”
4. and the depth of the hole should be 0.35”. Tighten screw to a snug but do not tight fit, then remove.
5. Clean debris from screw-hole, place lock washer first then electrical ring on top thread, screw until tight.
6. Install EZBridge per mounting instructions and continue to next step.
7. Connect opposite end of the grounding wire with ring to earth-ground or mounting pole.
8. If using the optional Teletronics surge protected PoE Inserter, connect grounding lug from PoE Inserter to
earth-ground and EZBridge ground wire to the same earth-ground point.
9. Continue normal installation process.
