New User with UTS10BI

[Anonymous user]

I've just bought a UTS10BI for home backup power and have already learned a lot from this forum. I do have questions, however, and hope that those presently using this unit can help me understand its functions a bit better.

I understand that I must provide 240 volt 20 amp power to circuits 9 & 10, which power the UTS. I presently have a 240 volt 20 amp circuit that powers an air conditioner. Can I wire this through through circuits 9 & 10? I have no plan to use an AC in a power outage and the generator that I purchase for home backup will not be able to power it anyway. When running on utility power, will the UTS rob enough power from 9 &10 to effect the operation of the AC?

I'm sure I'll have more questions, but thanks in advance for those that are willing to answer these.

Update: I've spoken with technical support and was told that the UPS draw on 9 & 10 is "incredibly small" and is basically the same as whatever is wired to that circuit.

You may use 9/10 out to power any 20A circuit, including the AC.
What the UTS takes to power its controller board is negligible. (if you have a clamp-on ammeter you can measure it).

Apologies in advance, don't mean to offend; make sure your AC is truly 240V/20A, many home ACs are 120V/20A and have a dedicated homerun wiring with a polarized 120V 20A -- | plug that many people mistake for a 240V plug. If that is the case you can still power your AC, just make sure you use the correct voltage.

Thank you, Friedrich, for your reply. I am certainly not offended that you gave me good advice regarding my AC circuit! Fortunately, it's a central unit that's hard wired to my circuit breaker box and is, indeed, 240V, 20A.
