F04 - Clamp Short - APC Power Saving BackUPS Pro 1300

The "F04" code on a Vector battery jump box typically indicates a fault or error within the unit or its connections. This error could be caused by a poor connection, a damaged battery clamp, or an issue with the box itself. To help fix the issue, try these steps:

1. Ensure the battery clamps are clean and not damaged.
2. Check the connections between the jump box and the battery terminals. Ensure the positive (+) clamp is connected to the positive terminal and the negative (-) clamp is connected to the negative terminal or a suitable ground location on the vehicle.
3. If possible, test the jump box on another vehicle to confirm it is working correctly.
4. If the issue still remains, consult the user manual or contact the manufacturer for further assistance or information on potential repair options.

F04 is a mechanism issue; the µProcessor doesn't know the position of the mechanism.
Take it to a Panasonic Service department for service.

Error F04 varies by machine brand/model.

Not sure bout the code. But if its turning off it may be due to ur cycling thermostat as per an over heating issue, check ur duct system and venting, u may also have a short in the heating element

F4, F04 is always door related.

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 don't say the model number. This makes it harder to diagnose. However assuming it is a K-Deck model (try searching around the web with your model number to see if it does match up with a K-Deck). Then F04 means the mechanism is locking up whilst trying to unload. In which case it's all to do with the Load Motor timing. This only applies to K-Deck models though. F04 on another model could be very different.

This is a printout of the fault codes

System Fault indicator is on and all other
front panel indicators are flashing.

Internal UPS fault. One of nine Internal UPS Fault Messages is displayed:
F01 - On-Battery Overload F06 - Relay Welding
F02 - On-Battery Output Short F07 - Temperature
F03 - On-Battery XCap Overload F08 - Fan Fault
F04 - Clamp Short F09 - Internal Fault
F05 - Charger Fault

F04 is "loading lock". most likely problem is that the timing of the gears in the tape loading mechanism is mis-timed.
