Question about CyberPower 725SL UPS System

2 Answers

Power is out

The back side of this 725 SL works fine. Front side (battery) Trips and clicks in and out after I plug it in (no load). Is the battery in it bad or is the aotumatic breaker shot? Can I fix it or do I just buy a new one? Money is very tight, so if I can fix this, I will...Thanks, Tom

    It's a couple of years old. Never turned off. Are these batteries replaceable by me?

  • walkertd1Tom Feb 04, 2008

    I still need answers. Can't afford to replace it if I can fix it.

  • walkertd1Tom Feb 04, 2008

    If it's definately the battery/batteries then I'll take it apart. Would it click on and off if it is the battery? Could the breaker be bad?

  • walkertd1Tom Feb 05, 2008

    So it is definately the batteries?

    how long you had this one? Seems that if it's been in service a while, you may be suffering from effects of dry batteries(yes, even the Gel batteries 'dry' out, if they are not exercised every month, with a full discharge/recharge cycle).

Sometimes you can buy the whole unit on a good sale for less than the price of the battery/ batteries.

Tom, usually those can be replaced by the End User. It's rare that they'd be sealed inside, but that does happen at times. The big issue is finding replacement batteries of same type/size fit, and you'd need to do that online.

    actually, until you can run it without batteries, you can't tell. That's the problem with lower end UPS units. They are for all intents and purposes sealed by mfg, especially the ones from China. Lotsofjunk makes a good point here..

Is there anything that can be done to fix the front outlets? They don't work. Back ones do.

The outlets that are used for Battery Back Up need a power cell that is recharged and ready to take over when a power situation requires action. If the battery no longer charges it must be replaced as the outlets will not have any power connection.

I have had my whirlpool dryer about 4yrs + (geq9800pw2) has always worked fine. Last week it started tripping ckt breaker toward the end of drying cycle. As of this morning, it blows ckt breaker...

leave off the oven and a/c breakers and plug dryer and reset the breaker. if not tripping occurs then one at a time trip back the oven first. if no trip then trip off again and trip the a/c. if no trip then trip the oven back. if trip you may have a wire problem. if dryer trip any way then possibly you have a short in dryer. check the heating element wires,power cord at the dryer side(terminal block).

Look in the manual. Probably a little button on the kick panel in the front passenger seat, just in front of the door. It resets a relay which trips if you roll over.

Due to office renovation, I unplugged and packed up my dell 725 printer. Now that it is back in my office, I cannot recall how/where to attach the power cord.

The socket is NOT likely to be on the BOTTOM, FRONT, LEFT-SIDE or RIGHT-SIDE or TOP.

So, look at the BACK -- both "straight-on" and swivelling it 45 degrees clock-wise or counter-clock-wise -- with a strong light shining on it.

Or, access and enter '725' and search.
Download any "support" documents that are offered.
Some of them will have pictures or diagrams.

Pump plugged in to grounded receptacle trips the

If by "trips the breaker" you mean the GFI then you are leaking current to ground, GFI's trip when there is an imbalance between the current going to the motor on the HOT side and returning from the motor on the NEUTRAL side, if it is tripping the GFI it is likely the sign of a failing motor.

Hi I have a Tripplite 3636VR connect up with 3 X 200AH batteries in series. The inverter works fine when connected to city power, when the city power fails the inverter takes over noramlly, I then go and...

check the system but you may have to turn off the batteries
the inverter is charging the batteries but when mains power fails , the batteries will be discharging back through the inverter that is dc converted back to ac
if you power on a genset and the ac is not phased correctly, what you describe will happen--- inverter ac from the batteries against genset ac to the inverter-
If you had mains power on then it would dead stop the genset because of the out of phase situation
it all has to do with the 2 wave patterns for ac current from each unit being in harmony and not working against each other

I dont know where the Dell 725 Printer Power Cord goes into the tower Which outlet on the tower

The Dell 725 printer power cord does NOT plug in to the tower. The Video Cable, on the other hand, plugs in to the tower's video output. Look for a connector like the one from the printer (often USB these days) to plug it in to the computer. There was a diagram that came with the computer that showed how to do all the connections, and the Power Cord does NOT plug in to the tower. USB connections are in various locations on your computer's tower, in the back and sometimes in the front too.
