    Hi
    thanks, it looks like it.
    actually does not show on manual. the breaker ref. pag 9 connects to the terminal block for battery circuit breaker control wiring and QD1, mounted between Q1 and QF1.
    also in page 46 of manual in the display unit in flow diagram between the ac/dc and dc/ac there is a earth connection and and in that earth connection is the breaker.

  • Vitor Barata Mar 22, 2011

    sorry its not connected to earth breaker switch but to abttery

Hi.

Try doing a restart procedure. Check pages from 35 to 37 in manual below. Disconnect connected devices. If there is overload because of a defective device connected, the first of the three leds at the bottom left hand corner will flash.

The UPS bypass switch may trip to test for the following reasons:

There is no AC power -LED 34 and LED 35 are flashing.
The battery has drained or is defective. LED 35 is flashing.
There is an internal fault (minor). LED 36 is flashing.
There is a short - The switch trips and the unit turns off. In this case the relay board is frequently location of the problem.

Here a picture showing the LED:

The unit also turns to test when the static switch is not closed (check also page 46 on manual). If the unit is starting up, try resetting to factory, by entering programming code 000 (see manual).

Here an online manual:

    Hi.

    OK, please check the parts indicated on manual.

    If there is a failure you will get a LED code, unless the problem is an internal short or major failure. In that case the switch will trip and the unit will also turn off.

    All the best.

    Hi.

    MGE was bought by Schneider Electric.
    I do not know if Schneider distribute power for older MGE UPS systems. Find the number in the website above and try giving them a call.

    If the part is not available, then the choices are bypassing the safety switch, or replacing it with a different battery overload protection or cutoff switch.

    Hi Vitor.

    The switch should be a load break switch, It breaks at stated KW load. the problem is the size and shape.
    If I am wrong and the switch is simply a cutoff (interruptor), it will be much easier to find.
    If you have a component shop nearby, take the switch there and have a look.

    I suggest dropping a message to Schneider, here the form.

    Regards.

    Hi.

    Not all models have the same features. By the way if the switch is a circuit breaker, rather than an overload, you simply need to replace it with a circuit breaker of same size.

    In either case the unit will work with or without the switch, only if the part is the load switch, in case of overload there can be damage to battery because the switch was jumped. If you jump the switch you must take care not to overload.

    If you really cannot find a part that fits, use a fuse or any circuit breaker safely placed inside the unit and soldered in place of the switch.

    Hi.

    Replacing with the original spare is the best solution.

    All the best.

It is most likely the fan element has blown. If you disconnect the element then test it again you will see if it doesn't trip the fuse then that was it.
