Re: Changing input frequency of Powerware 9315-80 Model...

Unfortunately, it seems that you UPS is mostly designed for 60 Hz. However, there seems to be an exception for 380-415V input / 380-415V output where 50 Hz is supported.

Of course, 380-415V is not usable for IT systems as is, you would then have to transform it back to 208V or whatever voltage your infrastructure is requirering.

Check out the table at page 2 of this document:®%209315-80%20UPS%20Data%20Sheet.pdf

One thing that is not specified in this document is if the UPS can be easily switched from one input voltage to another or if you need to replace some parts.

Hope this helps.

Can I replace the fan in a live powerware 9120?

hey dude your problem is so simple..below are my solutions.
if you already secured the fans for the replacement then its easy for you to do it, try to totally shut down your UPS removing the input and battery supply. avoid replacing the fans with power, its to dangerous. it consist of almost 400VDC inside in it.
call me if you want +63923 3024 585

Model 9155 display says: "UPS

bypass is not available because your input is going in one phase rotation and the bypass is going another. Both input and bypass needs to be a clockwise rotation. A cheap phase rotation meter will fix this. Call me at Gruber Power Services for free tech. support 800-658-5883 x256 ask for Eric

The bypass mode indicator is blinking, what do I need to do?

my be its indicating that the bypass mode is not available because power input is not of range that the ups is designed to take, check the ratinng of ups and use amultimeter to check whether the input matches the input. also depending on the type of ups this could be a code for a fault. please avail the ups type.

Attaching a generator to Powerware 9120 UPS

Power ware has a powerpass bypass switch for $200.00.

There is two inputs on this bypass switch. One for power, and one for the generator.

One ouput for your UPS. There you have it... There is your soluiton. I might add one other thing called a Power Guard, PMM117, to monitor the power of the backup generator. The time delay of this device will prevent over current from cooking your UPS power supply.

They also have a Hardwired version that is more expensive for you 5, 6 ,10KVA UPS. So a automatic bypass switch is what you need.

The UPS dont go to on batteri

Replace the batteries with new one then power the UPS without load for three hours or more so that the batteries can be charged. Then disconnect or switch off power to the UPS and observe if it will till be on using the batteries. If it will be ON then your problem is solved but if it goes off then your UPS is on BYPASS

    50Hz to 60Hz conversion

    Hi, Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards. P.S. The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.
