If you got the store bought APC 350 UPS, you most likely overloaded them, and killed them beyound repair.

People should never buy a 350VA. They are way to small for power supplies most of us now have. you need to start out to 1000VA plus you need to do the math to figure out how big of a UPS you actually need in the show room.
What am I talking about? What is the significant, or the math of what I am saying here. 115V x 1 amps = 115VA x .778 power factor = 89.47 watts Start up 50 watts = 39.47 watts
115V x 2 amps = 230VA x .778 power factor = 178.94 watts Start up 50 watts = 128.94 watts
115V x 3 amps = 345VA x .778 power factor = 268.41 watts Start up 50 watts = 218.41 watts
115V x 4 amps = 460VA x .778 power factor = 357.88 watts Start up 50 watts = 307.88 watts
115V x 5 amps = 575VA x .778 power factor = 447.35 watts Start up 50 watts = 397.35 watts
115V x 6 amps = 690VA x .778 power factor = 536.82 watts Start up 50 watts = 486.82 watts
115V x 7 amps = 805VA x .778 power factor = 626.29 watts Start up 50 watts = 576.29 watts
115V x 8 amps = 920VA x .778 power factor = 717.76 watts Start up 50 watts = 667.76 watts
115V x 9 amps = 1035VA x .778 power factor = 805.23 watts Start up 50 watts = 755.23 watts
115V x 10 amps = 1150VA x .778 power factor = 894.70 watts Start up 50 watts = 844.70 watts
115V x 11 amps = 1265VA x .778 power factor = 984.17 watts Start up 50 watts = 934.17 watts
115V x 12 amps = 1380VA x .778 power factor = 1073.63 watts Start up 50 watts = 1023.63 watts
115V x 13 amps = 1495VA x .778 power factor = 1163.11 watts Start up 50 watts = 1113.11 watts
115V x 14 amps = 1610VA x .778 power factor = 1252.58 watts Start up 50 watts = 1202.58 watts
115V x 15 amps = 1725VA x .778 power factor = 1342.05 watts Start up 50 watts = 1292.05 watts
115V x 16 amps = 1840VA x .778 power factor = 1431.52 watts Start up 50 watts = 1387.52 watts
115V x 17 amps = 1955VA x .778 power factor = 1520.99 watts Start up 50 watts = 1470.99 watts
115V x 18 amps = 2070VA x .778 power factor = 1610.46 watts Start up 50 watts = 1560.46 watts
115V x 19 amps = 2185VA x .778 power factor = 1699.93 watts Start up 50 watts = 1649.93 watts
115V x 20 amps = 2300VA x .778 power factor = 1789.40 watts Start up 50 watts = 1739.40 watts

yes you can but you need a coupler for the extra battery back, you can find one at an electronic store.

### Hi, We have KEB F5 inverter on our machine model

If you are connected to the inverter with COMBIVIS, go to parameter FR.01 and enter a value of -4. This will set all parameters back to factory default.

You may be having an issue with the inverters software verison. As long as the inverters are the same part number, you should be able to download the parameters without any issue. There may be some unknown parameters but you should be able to hit ignore and keep on downloading.

### I recently purchased a schumacher 410w inverter, while it came on right away and powered my electrical device the cooling fan never came on. Is the fan supposed to run all the time, once its connected.

I recently purchased a Schumaker 410/820 watt inverter. I immediately hooked it up to a brand new deep cell batery I had purchased just prior to receiving this inverter.
I plugged in several devices to make sure the inverter worked and to get some idea of what devices I can expect this unit to handle.
I noticed that the fan only ran when I plugged in a device that drew a certain amount of power from the unit. I also plugged in a CPAP unit to make sure the inverter would operate the unit properly, and noticed that the CPAP only drew 38 to 40 watts of power and the cooling fan on the converter never came on. When I plugged in an oscillating fan it drew around 128 watts from the converter and the cooling fan immediately came on when I turned the fan on. Based on that, I would assume that the cooling fan in the converter only runs when there is enough power being drawn through the inverter to cause the inverter to heat up enough to cause possible damage to or failure of the inverter. I haven't taken the time to find out the power draw at which the cooling fan will run. Hope this helps.

### This is a Wagan 2003-6 400Watt with USB DC to AC Inverter. Worked great for almost a year. Recently fan was varying in speed under load. Then finally blew my vehicle cigarette lighter receptacle fuse. ...

A few thoughts on this. With the transistors, if these are a darlington style of transistor, it might show a short on a good transistor. The USB "transistor" is a voltage regulator, 12v to 5volts dc. With the inverter input, some inverters use a diode in the input to protect against connecting the inverter by reversed leads. This diode might be shorted and be causing your problem. If it comes to changing the transistors, it might be cheaper in the long run to buy a new inverter. The transistors might be problematic and might not be the only thing problematic. Experience here talking!

Hi , i'm sorry but i dont really understand your question , assuming the current draw is around 45 amps then 2 /0 GA is fine , just keep your leads from your panel nice and short , the connection kits are sold by sunforce and there plenty of suitable connectors on the market

### Keb inverter and lenze inverter

I would have to say that you will not be able to swap the KEB inverters with the Lenze inverters or the Lenze inverters with the KEB inverters.

The PLC ProfiBus system would most likely need to be re-programmed for the change.

### I have a cobra cpi2575 inverter and the led screen keeps saying OPP even after i unplug everithing exept the power cables

We hope it is still new and can be returned, do it as fast as possible.

You will find it hard and very costly to repair it.
Starting ad 75.00 an hour with the bill being around 175. before your running again.

If at all possible Return it and consider it a lessons learned and purchase an nicer Pure sine wave inverter in the 1500 watt size area. they tend to be much better and are much more capable of running full time under a load.

Sad new I'm sure for you SORRY. I'm a Seven inverter owner with only one good inverter to show for all the trouble.

### Where i can buy toshiba satellite p10-304 display screen inverter

Hi,

You will be able to purchase an inverter board here>>>>>>>

http://www.impactcomputers.com/k000009570.html

Take a look at the back of the inverter for a copper coil, if youre-solder the solder points around the coil you may find it works againas components that suffer from extreme heat the solder joints drycausing bad connections, re-floating the solder solves the problem in90% of cases.

If you don't know how to remove the inverter from the bottom of the screen then please post back.

Regards.
