Problem (Stand by) Silcon 40kw 400v UPS (SL40KHB2)


Your English is OK, I can understand it! I can't say for sure but I believe that some UPS units don't come on unless they batteries are charged and in good condition. Try to locate the cells/batteries and check each one individually with a volt meter. The voltages should be almost the same on all batteries (usually 12 volts).

Silcon DP360, 3-phase 60kva, 400v, year 1993 1. Its old but working perfectly, after I changed the battery bank, because of collapsed cells, it still runs as expected but, I cant get any power readings...


#1. You should call APC Technical Support. It's free, and they will help you. You should get voltage even without a load on the unit.

#2. There is a Tripple-Slot unit for this device. It's specific for the Silcon based units. Read the manual, and there is a PN that you need for it. If it doesn't say SILCON, then it won't work. (I tried).
