An important step in the selection process is to protect against surge damage and line noise distortion on every connection. As mentioned previously, surges and line noise will attempt to reach a device (or system of devices) through every connection, not just through the power line. If it cannot get through the "front door" (the power line), they will go through the "back door" (the communications lines or signal lines). The rule of thumb here is very simple: "Every Connection Needs Protection!" Every cable that connects to a device (or system of devices) must be protected against surges and line noise. Every cable, whether it is the power cable, the modem cable, the network cable or the coaxial cable, it all needs to be connected to and protected by a Tripp Lite Surge Suppressor. Tripp Lite offers models in a variety of configurations to satisfy the connectivity and protection needs of every application.
