Hi Giz
it is likely to be connected to the mains via a local isolator ,the cable feedind the unit will nead to be disconected there, isolate the local isolator and disconect it.
the batterys are likely to be in three banks ,i would remove the negative first which is likely to be common to all of them ,(i think this is the correct precedure) ,then the positives ,then any links between the batterys ,then take it out ,have fun!
