UTS10BI Secondary Power Source and Circuit 1

This was originally posted on APC forums on 2/23/2013


My electrician has wired my UTS10BI and I am now going through the circuit setup. I plan to purchase a Honda inverter (model yet to be determined) for my Backup1 power source. I presently have a Honda EU2000i that I will use as my Backup2 power source. Ultimately, I would only use Backup2 to power just my furnace overnight in order to save fuel. My question/problem is this:

My furnace is presently wired to UTS circuit 1. The manual says that circuit 1 may not be set up for UPS or EITHER backup power source. It that true for any power source to Backup2 or just a UPS? I have the sinking feeling that I will have to move the furnace to another UTS circuit so that either Backup1 or Backup2 can power it.

Your insight would be appreciated.

The design idea is that the connivence outlet (circuit 1) also charges the UPS (backup2).  When the UTS is running on backup2, which in most cases would be a UPS, the UPS can not supply power to circuit 1 and also at the same time charge itself from circuit 1.

Circuit 1 is what provides power to the convenience outlet on the face of the UTS. The generator can be the only Back up source for Circuit 1 in order to power the typical UPS (or the Honda inverter in your case).

in short, you are correct. You will have to move the furnace to a different circuit and set that circuit for UPS only which will then be ultimately your inverter.

Thanks for your reply. Although I don't really understand why Backup2 cannot both power circuit 1 and the power outlet on the face of the UTS, I accept that it's a circuitry issue that cannot be changed. I will put the furnace on another UTS circuit.

Once I move the furnace to another circuit, I do wonder why that circuit cannot be set to EITHER, instead of UPS only, as you've advised.
