Hi There, hopefully you have not been injured by the advise thats been posted by some of the other users,
if you are decommissioning the system I guess the critical load is to be powered down if so Follow these steps:
Dont work alone
open the door of the ups and open the battery switch/breaker this will take the batteries off charge.
if the cabinets are original best power battery cabinets they will have a breaker in each at the bottom knock these off
next back at the UPS open the ups output switch
open the static bypass supply switch
open the rectifer supply switch
unit should power down
next isolate the mains into the unit from the switch board
Check all dead at terminals under the cover under where the switches in the ups module
***********VERY IMPORTANT**********BATTERY VOLTAGE IS AROUND 445VDC ON THESE MACHINES***************
Batteries: if you split the links between the batteries this will disconnect the battery voltage because they are all in series wear electricians gaultlets about 25 quid from RS or arco Batteries are always on!!
Repeat on cabinet 2 until all the battey links are removed,
If you can get a pallet truck and move the UPS out to where ever its being collected dont remove anything out of it unless you have to.
lastly if you can move the batteries with the pallet truck in the cabinet it can be done other wise remove batteries from the cabinets and put them on a pallet.
Heres the good part!! if you get all the stuff outside ring a waste carrier to collect it you will need a waste consignment because Batteries are hazadous waste.
you should get a couple of hundred scrap value for the batts and the transformer in the UPS..
Then go for a pint!!
