After clarification with our responsible department we recommend you the article that you find on the following place:

Helpful answer
You won't find any information about network, IP, etc. for this UPS because it can't be managed via network.
You are left with USB or serial.
Yes, it works with one of my devices (Thecus N7700), but not with the other (QNAP 219).
The communication options between the NAS and the emergency power supply are very limited and are not covered very well in the manual.
Conclusion:
I am very satisfied with the emergency power supply.
However, I am very dissatisfied with the instructions and the connection/communication options.

The correct replacement battery for the APC Back-UPS Pro with 900 VA and 540 W (model BR900MI) is the battery labelled APCRBC164. This is a VRLA (lead-gel) battery with a capacity of 128 Wh and a typical service life of 3 to 5 years. It is used specifically for this UPS model.
Automatically generated from the .
Unfortunately, there are two APC900 models - old and new. The new models need no. 164, the old ones need no. 123. Unfortunately, I ordered no. 123 first and then had to send the battery back. Tip: simply remove the old battery and compare the photo. If it is split in two, it will be no. 123. If it is a single large block, it is no. 164 (just look at the photos at Galaxus).

Hello Yoichi, Yes, the cable was included in my delivery.

The answer is a bit like the joke from "Radio Yerevan" in the 80s. "In principle yes, but.....". Let me put it this way: this device is network-compatible, but not standalone. I.e. it is connected via a USB-to-Smart bridge with a proprietary protocol (Schneider Electrics). In the past they had switched to open source compatibility, now it's just proprietary. So let's assume that the device you are operating and is connected to the UPS with USB-A to Eth (Smart) has the Windows OS. Then you can set this up with the proprietary software from Schneider Electric, the documentation can be found at: https://www.se.com/it...
Then you can also download the software and see if it runs, this also works without a group, but to see if the installation goes well: https://www.se.com/it...
The software you need to look for is: Power Chute Personal Edition 3.1.0 for Windows.
Otherwise I have to warn you. I use the group for a NAS (Truenas Scale) and a second one for a Linux computer under Tumbleweed Opensuse and despite a lot of reading and trying I have not succeeded in accessing the device, the reversed engeneered interface, which was quite capable of doing so under Linux, no longer works (because the protocol is no longer released, consequently NUT https://networkupstools.org/ for Linux is not executable with the part, at least I did not succeed. Locally it works very well and it worked well before. But you will only receive an email and SMS if the device using the UPS is running Windows and Scheider's software. (They have probably been bought in some way).
If you want to use open software or if you want the UPS group to be able to communicate independently, I advise you to use Chinese brands with simple LAN technology (like Blue Walker or similar) because Ethernet never lies. Or you have to dig deeper into your pockets to have a mini operating system standalone on board that can send an email. Because the price range you are looking at does not normally have this standalone functionality. I hope this helps you. The link to the manufacturer will take you to the manual, which I would read very carefully.
Please note: all information is based on personal experience, no guarantee or assurance of correctness, completeness or other responsibility is given or assumed, you alone are responsible for your purchase decision. Good luck!
P.S. Reliability: it's really very good. They run quietly, don't stink and the battery is easy to replace. The automated self-tests are also good and programmable.

This will probably not be enough. Because if your PC is running at full load, it will "say" more than 540W. It would be helpful to know which power supply you have, the UPS should have the same maximum output as your power supply (otherwise the power supply can only draw as much power as the UPS delivers). The graphics card and CPU alone draw more than 540W under full load (according to digitec, up to approx. 700W and this does not include fans and other components). It also plays a role what your goal of the UPS is, should the operation be ensured in the event of a short power failure, or should the UPS also last longer? Then it is no longer the maximum output power but the capacity of the battery that is decisive.

The output of this device is low. From the manual, maximum output:
540W or 900VA
That is not included with this UPS. I used one from an old PC.

Hello, I have not measured it, but the UPS has an efficiency of 97.4% in no-load operation. At 540 watts, this makes a loss of approx. 14.04 watts. However, since the UPS should be max. 70% loaded, this makes approx. 9.8 watts.

Unfortunately, the product manager was unable to provide any information on this matter, so we can only ask you to contact the manufacturer directly. We are sorry about this: https://www.apc.com/hr...

Hi, I have a DS-Slim that works exactly the same, just perfect. The way I got to know Synology, it will also work with your NAS.
In my knowledge, the UPS has a USB interface for Power Management by one device, like a server or NAS. I am joy sure you can use the SNMP protocol over USB
Hi Marvin, there is a fan inside, but it is quieter than my NAS. However, switching to battery is clearly audible (several times a day for me). The behaviour of the display cannot be influenced, not even by APC software ... but it switches off automatically. Unfortunately, the shutdown only works via USB. The network connections cannot be used in this way. I have connected the UPS to the NAS via USB and shut down my WIN server from WinNUT. MfG digimouse

The C13 connection can be mitigated with adapters (e.g. https://www.digitec.ch/de/s1/product/steffen-umwandlungsstecker-3-pol-typ-j-stromadapter-240497) or appropriate busbars. For the push message, this UPS must be connected to a "software" (i.e. PC or similar), "DIY" solutions, e.g. with Raspberry Pi, are of course also great and simple. Otherwise, the thing simply beeps loudly when configured accordingly. I have several of these UPS in use, partly on NAS (with such software) partly "dry" on network components. I reckon with min 5 max 10 min at half the nominal load (depending on the type of device).
Helpful answer
Yes, exactly. There must only be this one connection through the UPS from the internal network to the outside world to provide protection when lightning strikes outside....
Helpful answer
Yes, it is the BR900GI model.

Hello
Yes, that's exactly how it's supposed to be, disconnect the existing appliance cable and connect it to the UPS. Reconnect the PC with the supplied IEC power cable C13-C14 (cold appliance extension, appliance connection cable, etc.), further appliances via e.g. Digitec 12457407 or 11305675 (C14 to 4x T13)....
Helpful answer
The APC BR900GI manual specifies the replacement battery type APCRBC123.
I can't give you a degree Celsius, but my UPS with all four connections occupied only produces a very slight warming in normal operation, which can just be felt with the flat of the hand. Therefore, I think you can "put it in a closed wall cabinet without hesitation".

Mine gives a runtime of 440 min (7.33 h) at 7w load. At 2w load, that would be easily more than three times as long (22h). It also depends on the age of the battery. But on the whole, the 900VA from apc has a very good price/performance ratio.
Helpful answer
It is described in the instructions:
http://www.apc.com/salestools...
There you can loop telephone or network connections to protect your switch from overvoltage via the network cable, for example. A LAN connection is probably only available on larger UPSs, and this is usually via an additional network card.

Thanks for your answer Beat
I have now asked the manufacturer:
30W for charging, 10W otherwise
