UTS6H Questions

[Anonymous user]

So I have a UTS6H that had been sitting in the box for going on 2 years now.. I finally got around to installing it and have a few questions.

I wired up the 6 circuits as follows:

1) Computer Room (This is a 42U Rack w/ some servers and a 3000VA UPS) (20 AMP Circuit)
2) Kitchen/Fridge (Fridge and 1 Outlet that powers the Toaster) (Not sure on AMP Rating, have to look again)
3) Living Room Outlets/TV (15 AMP Circuit)
4) Main Floor Lights (15 AMP Circuit)
5) Kitchen Outlets (?? Amp Circuit, need to re-verify)
6) Basement & 2nd Floor Lights (15 AMP Circuit)

Backup 1 is wired with a 10/3 whip to a Yamaha EF2800i (Manual start). Planning on replacing this with a UTS10BI and a Yamaha EF6300iSDE in the future so I can provide power to more circuits.

I also have a 3000VA UPS which I plan on plugging into the UPS outlet (I am also setting this up with extended run batteries. Although it is a 3000VA normally wired to a 20AMP twist lock, I re-wired it as a 15AMP plug so it will provide longer run time with the lower load of the 15AMP maximum)

The question I have is how I should wire up a few different things. Specifically the UPS, and some questions around Circuit 1 - questions below.

1) Where should I plug the UPS in? Just any random outlet that will lose power during a power outage - or should this be plugged into a outlet that is powered by the generator/ATS during an outage? (So that it will recharge during the outage)
2) I noticed that in the Operations Manual on Page 11 it states: "Note: Backup power source availability varies for some circuits - The UPS and EITHER backup power source options are not available for: Circuit 1 on all units and the designated 240V circuits on the UTS6BI or the UTS10BI." Why is Circuit 1 unavailable for UPS or EITHER? Is it available for Uninterruptible? I wanted this circuit to be powered by UPS until I can fire up my generator.

hello,

i have got some feedback for you on this.

Backup 1 is wired with a 10/3 whip to a Yamaha EF2800i (Manual start). Planning on replacing this with a UTS10BI and a Yamaha EF6300iSDE in the future so I can provide power to more circuits.

The Yamaha EF6300iSDE is a single phase/split phase generator and would certainly be compatible with the UTS10BI.

The question I have is how I should wire up a few different things. Specifically the UPS, and some questions around Circuit 1 - questions below.

1) Where should I plug the UPS in? Just any random outlet that will lose power during a power outage - or should this be plugged into a outlet that is powered by the generator/ATS during an outage? (So that it will recharge during the outage)

The derated 3000VA UPS should be receive it's input power from the "Convienience Outlet" located on the face of the UTS.

2) I noticed that in the Operations Manual on Page 11 it states: "Note: Backup power source availability varies for some circuits - The UPS and EITHER backup power source options are not available for: Circuit 1 on all units and the designated 240V circuits on the UTS6BI or the UTS10BI." Why is Circuit 1 unavailable for UPS or EITHER? Is it available for Uninterruptible? I wanted this circuit to be powered by UPS until I can fire up my generator.

Circuit 1 supplies power to the "Convienience Outlet" located on the face of the unit. The UPS being powered from the "Convienience Outlet" can not
in turn supply power to itself while operating on generator. This is why the only acceptable source for Circuit 1 is back-up source 1(Generator) and UPS.

That makes sense.. Okay so Circuit 1 can be powered by Backup Source 1 - Generator.. That should be fine then since I already have a UPS on Circuit 1 (It is a rack of computer equipment). It should be fine until I start a generator manually.

Much appreciated on the quick response. Now it makes sense on why circuit 1 is not usable in that setup.

you're welcome

One last question..

I currently have the UTS6H wired to my YG2800i via the L5-30 connection. What is the maximum generator size the UTS6H can support when wired utilizing the L5-30 plug? How many watts cabled this way vs hard wired?
