SOURCE: Overload LED lit, constant warning tone, no load

you may have to many things plugged into the ups, it is not good to plug a power bar into one of the outlets of one of these as you are OVERLOADING the device with more power than it can produce

I have the same PCB on my Deltec PRR2200i. I at least know a few things about the circuit now. I had 11 transistors explode on mine and am replacing them now. Sadly I have not managed to track down a circuit diagram.

Powerware5115 will not switch on


A weak or dead battery pack its the main reason of a unresponsive/good health UPS, but never forget to test the electric cord, the fuse and the protective relay.first, this sounds too simple, but thats a common fault.

Battery pack must have at least 5 volts with half amp of current to power up the UPS internal relays, giving electric power to the main switch.

To rise the 12/24 DC volts to 115/120 AC volts, the UPS uses some electronic components (semiconductors) called MOSFETS , and sometimes, blown (browned) MOSFETS on the electric board are the most desastrous cause of a unresponsive (completely dead) or faulty UPS. (I remember that some time ago I see a TRIPP LITE SMART 1500LCD UPS with twelve blown MOSFETS, when happened, that kind of fault must be saw like a little volcano!).

If you know how to take all the safety electric measures, and how to use a portable voltmeter, you can test the voltage/amperage on the battery pack, the electric cord and the replaceable fuse (if has any). Basic and intermediate electronic knowledge is necessary to test MOSFETS and other electronic components on the circuit board.

Can't get any power on the battery side of my ups


If you have had that UPS in service for two years, the battery could be dead in which case the issue of backup power is moot.

APC PRO1300 F04 CLAMP SHORT ERROR CODE WHAT DOES IT MEAN AND HOW CAN I FIX?


F04 indicates that "Clamp Short" it could be anything, but the word "clamp" reminds me of a varistor / MOV, which is the component that clamps short when there is a voltage surge condition and comes back to its normal state, an open circuit, when the voltage surge is gone. Sometimes it clamps short for good when it is hit by a large surge or just by absorbing and shunting to ground many small surges.

You can brain dead the UPS to check if that resolves the issue. This brain dead test helps to reset the internal circuit of UPS.

1. Disconnect any attached load.
2. Turn off the UPS
3. Unplug the UPS from the wall socket.
4. Disconnect the UPS internal battery.
5. Push and hold the "On" button on the UPS for 5 seconds.
6. Reconnect internal battery.
7. Plug UPS in to known good power source.
8. Turn the UPS ON.

If the same issue remains even after brain dead then you have to replace the UPS. This UPS comes with 3 years of warranty, if it is under warranty you can contact APC support at 800 555 2725

If the UPS is out of warranty then you can participate in APC Trade-UPS program. APC has Trade-UPS program where in you can trade your old unit and get a new unit with great discount. You will also get a return shipping label to ship the trade-in unit to us. You can refer to the below mentioned URL.

Display will not come on plugged in or not


The UPS needs to have a good DC Buss for it to work. Before you buy the new battery disconnect the battery & unplug it from the wall. Push the on button to reset the logic. You may see the display flash breifly. Install the new battery. Then plug in the UPS and turn it on and enjoy

High frequency alarm sounds even when all components are unplugged from unit...even if I turn the unit off. The only way I can get it to stop is to unplug the unit.


You may have a problem with a Flat battery? Try taking the battery out and charging it, or swap it for a known good one, if this will not fix it, then you have a failure within the electronics, if this is so then it will need to be serviced by a professional.

Its not starts properly,my batteries are in good condition


Normally if this UPS is in working condition and the batteries are also good, you should be able to start the UPS by just using the battery cabinet. As soon as power is applied the fan must run and the 4 yellow led for battery/load should lit up. If it is completely dead, then a qualified technician will have to check the internal circuit. It has one main board on which all power components are mounted and a separate control board. Generally there is a 80/100 A than goes opened. I hope you can give us more information if the UPS is completely dead or the led comes up

CP685AVR/BF685 Power Contro.


It is likely the battery. These batteries are designed to last 3-6 years in a UPS. The good news is that if it is the battery, it is completely user replaceable and you'll have a Cyber Power unit that works just like new with a new battery. What may have happened is that the battery was weak, and you may have had a slight dip in the AC power. This caused the Cyberpower unit to switch over to the weak battery which couldn't handle the load. The unit then turned off. When you press the "ON" button, the unit will go through a self-test that checks all of the components and the unit will not turn on and be functional unless all of the components come back with a PASS, including the battery. If possible, test the battery with a voltmeter, it should read around 13.5, but not lower than 11.5v DC. However, with the unit over 3 years old, it almost certainly the battery. Here's a link to a replacement battery for the CP685AVR: http://www.batteryinternational.com/cyber-power-cp685avr-ups-battery-ups-batteries-f1.html

Hope this helps.
