Will not shift back to commerial power

My first thought was just that you need an Uninterruptible Power Supply which uses a battery and inverter to maintain the power in milliseconds. However, this is a full size commercial fridge like I use in commercial kitchens!

The specs say it is 115v/60/1, NEMA 5-15P, 2.8 Amps, 1/3 HP, so it is well within the capabilities of a larger UPS. This will work, it is 5 amps.

Many models of UPS's will not power up if the internal batteries are no longer working to spec. There is no point in having a UPS if the batteries are dead!

Other types of common faults are a blown power fuse, or a defective controller board, or a defective switch. If the fuse is blown, it is best to investigate for the reason it blew before replacing it and thinking it is safe.

1. Four beeps every 30seconds (On Battery LED will be illuminated)
This alarm indicates that the Battery PowerSupplied outlets are now supplying battery power as opposed to power from theutility. If the UPS determines that the input utility power is unsafe for yourcomputer equipment, the UPS will switch to battery power.
Note: Ifthe power disturbance is brief, you may only hear one or two beeps.

2. Continuous Beeping (On Battery LED will beilluminated)
This alarm indicates that a Low Batterycondition has been reached and that the UPS will soon shutdown. Once the UPStransfers to On Battery operation, it can only stay on battery for a limitedamount of time. The UPS will sound this alarm about two minutes before thebatteries are totally exhausted. Once exhausted, the UPS will shutdown and turnoff its output power to your equipment. If you hear this tone you shouldimmediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (BackUPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected anOverload condition after it has performed a self-test during start-up.

4. Continuous Two-Tone Beep
This alarm indicates a severe Overload wasdetected while the unit was on-battery operation. This tone will continue tosound until the unit shuts down.

5. Continuous Tone (On Battery LED will beflashing)
This alarm indicates that the battery-poweredoutlets are overloaded.

6. Continuous Tone (On Line and On BatteryLEDs flashing) Back UPS OFFICE 350,400, and 500 ONLY
This alarm indicates that an internal UPS faulthas occurred.

we have installed a new ups but the battery light indicates red light even though its on charge

The internal automatic battery test is picking up some differences between the actual value of the battery to the mathematical calculation used in the software. Normally if you do a battery impedance test you would find that the batteries would be consistent and therefore replacing the batteries may not be the solution. Once you transfer the UPS on BYPASS and then recycle the power you would clear the alarm. However on the next internal automatic battery you would be getting the same alarm again.

At times this may be a software issue or an SNMP problem. Normally to refresh the battery data for the UPS monitoring software we carry out a battery discharge test. Please consult with the supplier if an annually battery discharge test is mandatory for the battery monitoring circuit to work well. Please let me know of the outcome

the commerial is in wide screen format, is normal.

This is usually caused by a popped circuit breaker on the UPS. From the UPS Manual:

Disconnect non-essential equipment from the
Back-UPS. Reset the circuit breaker (located
on the rear panel of the Back-UPS) by pushing
the circuit breaker button fully inward
until it catches.

You can find the user manual here: http://www.refurbups.com/KB-M-Backups

Did you ever get a resolution to this issue? I have the exact same problem. Someone advised that I should ensure that the Sleep mode is disabled through the config but that is already the case. Do you by any chance have the UPS in a non-air conditioned room where it might be getting too hot? Secondly, do you have both the battery leads connected to the battery pack or just one of the pairs is connected?

1) Switch Off the UPS and unplug all Loads (like System, Monitor etc.) from UPS.
2) Switch Off the AC Power (Input Power to UPS).
3) Press the UPS Power Switch constantly unless you hear 2nd BEEP Tone. As soon as you are hearing 2nd BEEP Tone, Release the Power Switch.
4) This is COLD START of all APC UPS that will reset any internal problem.
5) If, however, the problem persists, contact APC.
