25. HD user manual What you need to know before installing your SEC HD Understanding power surges and surge suppression Power surges can be caused by external influences for example lightning or utility distribution problems or they can be caused internally for example starting and stopping inductive loads such as motors One of the most common causes of power surges is lightning When lightning strikes the ground it produces an enormously powerful electromagnetic field This field affects nearby power lines which transmit a surge to any device connected to it such as lights computers or environmental controls like your SEC HD Lightning does not have to strike a power line to transmit a surge Surge suppression devices offer some protection from power surges Because it is not possible to internally protect this product completely from the effects of power surges and other transients Phason highly recommend that you install external surge suppression devices For specific recommendations see your electrical contractor If you do not take these precautions you acknowledge your willingness to accept the risk of loss or injuty Reducing electrical noise using filters Electrical noise is caused by high voltage transients created when inductive loads such as power contactots are switched on or off The strength of the transients can be over 1000 volts and can vaty with the type of equipment and wiring as well as several other factors
