Liebert UPStation GXT2700RT-208 (GXT2700RT-208B) UPS System Questions & Answers
I want to operate a photocopy machine ( 115 V - 60
You need a frequency converter and voltage changer. It must have high surge ability to run the load you want to power. Copy machines will draw a lot of power and most converters are not suitable for this task. If you still need help post a reply with the tech spec of the load.
Hope this helps
Thanks for using FixYa

Covert 230V 50Hz to 230V 60Hz
To convert to 50Hz will be expensive as the Aircon needs alot of startup power. You could ask maker if 50Hz will be ok, usually motor will run slower so unit will be less efficient, alway check with maker. Or try supplier to see if they will exchange for what you ordered first.

50Hz to 60Hz conversion
Hi,
Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist.
Hope this be of some help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.
P.S.
The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.

Liebert gxt3 1500
staticbypass is actvated by the main control card via the press button swith,to transfter back to online mode its still the control card that do the timing for the transition to take place so i would suggest you test with another control card or try and be patient and see if it takes longer time to transfer back to online mode.

Battery over voltage
did you replace battery recently if yes,what is the ah of the new one you moved in,hope its the same ah with the one you moved out,if all batteries are new try to self drain batteries with battery tester and retest again with ups.

Liebert gxt2-10000rt208 fault indicator and A + E LEDs on. Did anyone know this alarm?
I'm going to go on a limb and say the unit also has the bypass indicator on as well, is that correct? A=On bypass due to overtemperature condition & E=On bypass due to inverter failure.
I can't see in the picture or hear it but is it beeping also? 1 second beep every 2 seconds? Thats on internal bypass. If none of this is true then you have a tricky problem.
