Hello. I just bought my first APC UPS (my second ups in general) - SMT2200I as home UPS and I'm a bit confused. In fact confused a lot. I've read through Installation Guide and Operation Manual which briefly (REALLY briefly) explains concept of Main Group and Controlled Group but it doesn't really say which outlets actually belong to those groups. I mean yeah there's group of 4 outlets labeled "Group 1" and what I deduced from manual is that this is what manual refers to as "Controlled Group" right? But it's just those 4 outlets or all 8 outlets and only this funky C19 outlet belongs to "Main Group"? if just those 4 then which group does this C19 outlet belong to - Main Group? Do i need to connect something to this C19 outlet? Existence of single outlet separated from the rest is quite confusing to me - what is its purpose? Is it protected or it's some kind of passthrough? All devices I've ever seen used standard C13. The only place I've seen C19 in my entire life was my previous home UPS but it used C19 only for own power supply, not as outlet.

Also can I use adapters like this to connect power stripe to UPS? https://www.komputronik.pl/product/250960/gembird-schuko-vde-0-15m.html

If I understand well I should connect critical devices like eg. networking equipment and 24/7 server to Main group and workstations, monitors, inkjet printers (I know about laser printers and all high-power stuff taboo), speakers and other insignificant devices to Controlled group right? Also my home electrical installation is a bit overloaded so when all devices startup at once fuse blows so I have to startup computers one by one or at least in 2 turns- so if I set "Turn On Delay" does it mean that after turning on UPS it will power up Controlled Group after such delay solving this problem for me? Or does it only apply to starting up group via drivers?

Sorry for amateur questions but I'm kind of new to UPSes topic and I bought this semi-industrial UPS mostly because my previous cheap UPS simply exploded putting home in danger so I really wanted to get something reliable this time ._.

Controlled are the 4 you think they are, main are the other 4 and the C19.

c13 are 10amp each and the c19 is 16amp

c19 tends to be more   for industrial applications, it doesn't have to be connected. In my case I chopped off the other end and wired it into 2 13a sockets to power my computer equipment as the UPS is in the loft whilst the PC kit is 2 floors down.

You can use whatever adapter you want, they also do a c14 to 4x schuko  https://www.alibaba.com/product-detail/IEC-C14-Inlet-to-Germany-Schuko_1712982984.html

keep in mind the c13 are 10 amp max

You can delay the startup   of each group to stagger it (not each of the 9 outputs, just the main 5 and 2nd 4) but at the end of the day the UPS will even out small surges and I doubt you will have any issues provided it is connected to a decent ring main.

If your consumer unit fuse blows swap it for a plugin   breaker, you can get direct replacements for old fuses.

If this is your 1st I would consider getting (if it didn't come with one) a network management card so you can control the shutdown on your computers as without you are stuck with it controlling a single device by USB. They are cheap on eBay 2nd hand.
