How I installed the ST-RJ45:
Once you know how it’s done, it’s rather easy to install this product, but a simple diagram to supplement the written
instructions would have made it much clearer.
– The cable from the DSL ISP goes into the input port of the ST-RJ45
– The cable from the modem connects to the equipment port of the ST-RJ45
– The green ground wire is connected to the ground screw of the UPS
