SBP5000RMI2U issue

This was originally posted on APC forums on 7/27/2010


Hi Guys

Before installation of the bypass panel is there any parameters we need to consider like the orientation of L-L or L-N, L-G from utility and UPS?
Co'z previously from my former company we counter some issue, as normal when the SBP was switch to Normal everything are doing fine but when we switch the SBP to bypass the utility breaker will tripped off and the UPS goes to Battery Mode.
No load connected to UPS and the SBP...,
Is there any issue if the out put of UPS is L-L and the Utility L-G or L-N with regards to the SBP?

Thanks

so there is an issue w/ the configuration, co'z our supply line is 220VAC L-L.., so can i say that possible this configuration cause the breaker to Tripped? but the SBP is break-before-make right?

Coz right now we have a client that need SBP for there 3 APC units of SURTD5000XLI, what im worry about is that, what if the breaker will Tripped off again. We can't afford to lose it..

any advice..thanks

just a few clone server and some router and switches, the breaker rating if I'm not mistaken was 60A.
But the time we switch the SBP to bypass there's no load connected for both UPS and SBP. What we are doing was that time just for a testing only, but i bit surprise when the breaker tripped off.

Did you put the UPS into manual bypass before operating the Bypass switch on the SBP5000RMI2U?

Nope, just only one of the branch breaker was trip. And that breaker was the supply breaker for the UPS.

Sorry meant to say automatic bypass... Read the upper right hand corner of the install document.

The UPS must be in bypass when rotating the switch. I'd try that then see if your still tripping the upstream breaker.

It is necessary to put the double-conversion online UPS into bypass before rotating the SBP switch because there is no guarantee that the UPS output will be in perfect sync with the mains input when the UPS is online. By putting the UPS itself into bypass, the output from the UPS in bypass is exactly matching the mains input, so there will be no change when the SBP switch is rotated.
