I have a problem with Galaxy 5000 80kVA // Redundant which has 4 year working
On the screen shows as follow:
Phase: Instalation initalization
External communicaction error
Inconsistent UPS personalizatin
Error code: 7-5-18
Can anybody help me which has some experience or make some suggestions about that what is wrong with this unit?

I think your Comuniccation cables DB9 are damaged or unplaged, from any ups.
check them all all 2 loops and serial cables in each ups. Or have remove jumpers to sel ct master slave ups.
