E.pu error in keb f5 inverter. the part no. is 09.f5.a1d-3a4a, ver. 1.0, 1.5kw. when powering up the drive, it gives 560VDC. please recommend what the problem could be.

The E.pu error is a general power stage failure.
Typically means that the unit has a defective power stage that would need to be replaced.
If it is an old inverter(early 2000's) there is a possibility that it could be a cooling fan problem since at that time there was a three wire fan used. May be able to replace the fan (must obtain from KEB) but there may still be problems with power stage. If it is from early 2000's then you might be better off replacing the unit with new current version.

ERROR power unit

General error of the power stage in the inverter. Part# and ser# of inverter would help troubleshoot better.

Maybe a problem with cooling fan if it is an older inverter. Typically when the error E.PU appears, it is too late. Power stage maybe damaged and would need to be replaced.

My acer screen is just blank i think it took a knock is there a quick fix

You may have cracked or broken the FL tube (backlight) or the inverter board has failed.
If the tube is broken, it needs to be replaced (or you can replace the whole LCD if you find one cheap).
If it's the inverter board, look for a microfuse on the inverter board (the one connected to the FL tube). These fuses will sometimes go for no reason. Check it for continuity with an ohm meter.
If the fuse is good, you may need to get the inverter board replaced.

To find out if you damaged the fl tube, you have to open up the LCD panel.
This is not a job for the faint of heart, and you have to be really careful not to damage anything.
They usually shatter when they break too, so be careful there.
You may just want to tap the backlight area to see if you hear rattling glass.

Check for loose or dislodged cables while you're in there.

I have a Heart Interface Freedom 20 Inverter/Battery Charger installed on a powerboat. The fan (cooling fan?) is making noise - it seems to be rubbling inside the unit. Is there a way to repair? Replace...

The fan can be replaced. It is very similar to some of the PC cooling fans. I've got the same problem (again) and will be replacing it soon. I will give you the fan specs once I remove my fan ( I think it is 4" 120VAC - will let you know when I repair mine).

My vector power inverter needs to be reset

Inverters use high power transistors to create an A/C voltage from a D/C input. These transistors are the common point of failure when the units are not cooled properly or used beyond their rated capacity. (Actually, you should always buy an inverter that’s rating for continuous use is well below what your actual need is). What’s most likely happened is that these have shorted out and need to be replaced. Unfortunately, replacement parts alone will likely cost nearly what a new unit costs.

Sorry to be the bearer of bad news; but you basically have a nice paperweight with some pretty lights and fans on it.
