This means waiting and wasting time. You can speed up the testing by setting LB very high so that the UPS reaches it quickly. Later you can set a more reasonable value.<br class=""></blockquote><br class="">After the first test and the NAS is restarted I had to change the setting battery.charge.low again to 80 <br class=""><br class=""><blockquote type="cite" class="">On most UPS units, there is a light which goes out. Some produce an audible clunk as the relays disconnect the UPS power outlets. You could also connect a light bulb to a protected outlet. It should go out when the UPS shuts down.<br class=""></blockquote><br class="">The APC produced an audible clunk. So the UPS was shutdown. I am not sure it was after 20 seconds. I have to clock that. <br class=""><br class=""><blockquote type="cite" class="">Example test:<br class=""><br class="">1. Pull power cord from wall<br class=""><br class="">2.
