Question about MGE UPS Galaxy 3000 UPS System
While attending to this unit I discovered that load supported through yellow phase had no power on static bypass and after resetting the unit it kept switching off after 10 minutes. What could be the problem?
What caused the UPS to transfer to Bypass? could be inverter fault, would you please check your battery set, maybe the input power is outside the tolerance and causing UPS to discharge the battery set , as well when battery set reaches the end of discharge it is causing the UPS to transfer to bypass and there is something missing on the input yellow Phase.
if the above is not true check the load type that is connected to the UPS output that is causing UPS to switch off in 10 minutes time.

SOURCE: case 1: 220 V, 50Hz applied
Did you measure with a true RMS meter?
If yes,the results are normal,but your ground connection is not very good.
The case has 110v potential (exactly half of the input&output 220v) because of the input and output capacitor filters (a capacitor is conectet from phase to casis and an other from neutral to chasis,thus resulting a 1/2 voltage divider). Because of this,the earthing is necessary.

SOURCE: when switched the bypass to
You didnt start the UPS correctly because the static switch was not on. The Static Switch has to be on to get a clean transfer of power. Check your static switch
