<p class="MsoNormal">Hi Guys<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a very small server room with one rack drawing around 8 amps.<o:p></o:p></p>
<p class="MsoNormal">I thought I was clever and installed an APC ATS to run the kit that only has single feel power input.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Well its been a disaster, final straw was 4am today when it caused both UPS’s to error and trip all breakers.<o:p></o:p></p>
<p class="MsoNormal">Bypassing the ATS fixed it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m thinking of abandoning the ATS idea or trying another brand like Eaton
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone have any thoughts on this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
