SOURCE: Tripp Lite SU2200 UPS has faults
For Tripplite UPS basically if the fault indicator is on you already have to check the power mosfets/IGBT on the circuit board. if you know the basic of UPS you dont need all those schematic diagram to check the thing. by the way, try to check your battery first if its still working. and if the battery is ok, go and check your inverter

There are 2 (very deep) screw holes at the back of the UPS, but you'll need a long (8"+) philips screwdriver to access them.
