What you can connect. Output is delivered on (1) hard wire 5-wire (3P + N + E), (1) hard wire 3-wire (1P + N + E) and (1) IEC 60320 C19 outlet. This is a distribution-board UPS, not a plug-and-play one — almost all of the load reaches it through a downstream distribution board or rack PDU rather than through outlets on the UPS itself. Total the real power draw (watts) of everything you intend to protect and keep it below 15,000 W.

Runtime at stated loads. Schneider publishes 5 minutes 30 seconds at the full 15,000 W and 14 minutes 30 seconds at half load (7,500 W). Runtime is not linear — halving the load more than doubles the time on battery — and these figures apply to a healthy battery at rated temperature. Recharge time is 4 hours. Ask SourceIT for a runtime calculation against your measured load rather than sizing from the headline number.

Extended runtime. Connect up to four SRTG192XLBP2 external battery packs (excluding the one supplied with the UPS), taking maximum system capacity to 17,606 VAh. Note that this is a maximum of four, not the ten supported by the smaller SRT models — do not assume the SRT figure carries across. The replacement cartridge for both the UPS and the pack is the APCRBC172.

Rack fit. 7U when racked, in a 306 mm (H) x 440 mm (W) x 700 mm (D) chassis, and rack / tower convertible. The rail kit is not included — order SRTGRK1 for the power module and SRTGRK2 for the battery pack. At 142.5 kg for the UPS alone, check the cabinet's static load rating and mount it at the very bottom. A single UPS plus one battery pack is 11U and roughly 260 kg.

Input and circuit — read this before ordering. The SRTG15KXLI is hard wired: (1) 5-wire (3P + N + E) plus (1) 3-wire (1P + N + E) terminal block, with no plug. It can be configured 1:1, 3:1 or 3:3. Maximum input current is 66 A per the data sheet, with a switching capacity of 100 A; the operation manual gives 100.2 A at 1:1 and 33.5 A per phase at 3:1 and 3:3. A licensed electrician must size and terminate the supply. Confirm the arrangement with your electrician and building management well before delivery.

Network management and monitoring. A network management card is pre-installed, so SNMP and HTTPS monitoring are available out of the box — but note the SmartSlot is occupied by that card, so there is no free slot for an AP9613 Dry Contact I/O card or a second management card. Dry-contact style signalling is instead available through the maintenance bypass signal (MBS) input and the parallel port. Schneider recommends PowerChute Network Shutdown for graceful multi-server shutdown.

In the box: Schneider does not publish an itemised package-contents list for the SRTG units — the operation manual asks you to inspect the package contents on receipt but does not enumerate them — so we have not invented one. A Smart-UPS signalling RS-232 cable is confirmed as supplied, and the network management card is pre-installed. Ask SourceIT if you need contents confirmed before a tender submission.

What is the difference between the 15,000 VA and 15,000 W rating, and how do I size the SRTG15KXLI?
VA is apparent power and W is real power. On many UPS families the watt figure is lower than the VA figure, and watts is what limits you — but the SRTG15KXLI is a unity power factor design, so it delivers the full 15,000 W. Add up the real draw of everything you want on battery and keep the total below 15,000 W. At this capacity you are almost always sizing against a measured load from a power meter rather than nameplate figures; ask SourceIT to work through it with you.

How long will the SRTG15KXLI run on battery?
Schneider publishes 5 minutes 30 seconds at the full 15,000 W and 14 minutes 30 seconds at half load (7,500 W). That is deliberately short — a UPS at this capacity is normally sized to ride through a dip and cover the start of a generator, not to run the room for an hour. For longer autonomy add SRTG192XLBP2 packs, up to four, taking the system to 17,606 VAh. Recharge time is 4 hours.

Can the SRTG15KXLI take a three-phase supply?
Yes, and this is one of the main reasons to specify it. It supports 1:1 (single-phase in, single-phase out), 3:1 (three-phase in, single-phase out) and 3:3 (three-phase in and out). Input is 380–415 V three phase or 230 V single phase, hard wired through a 5-wire (3P + N + E) plus 3-wire (1P + N + E) terminal block. In a Singapore building where the riser is three-phase but your rack load is single-phase, 3:1 is usually the configuration you want.

Does the SRTG15KXLI produce a sine wave output, and will it work with an active-PFC power supply?
Yes. It is an on-line double-conversion design with a sine wave output rated at less than 5% voltage distortion, so the load is fed from the inverter continuously. That is exactly the output type active-PFC server and workstation power supplies expect — unlike the step-approximated output of entry-level line-interactive and standby UPS units, which some active-PFC supplies reject outright.

What does the XLI suffix mean on an SRTG unit?
XLI denotes the extended-runtime international build. On the SRTG range it also means the unit is supplied without a rail kit — the power module needs SRTGRK1 and the battery pack needs SRTGRK2, both ordered separately. Note that SRTG part numbers are not interchangeable with the smaller SRT range: the battery pack, the replacement cartridge and the maximum pack count are all different.

Which replacement battery does the SRTG15KXLI take?
The APCRBC172, quantity 2. The internal batteries are sealed maintenance-free VRLA on a ±192 VDC bus at 9 Ah. Note this is a different cartridge from the APCRBC140 used across the SRT 5–10 kVA range — do not order by analogy. Expected service life is three to five years, and heat is the main determinant.

How much rack space does the SRTG15KXLI need, and is the rail kit included?
It occupies 7U in a 306 mm (H) x 440 mm (W) x 700 mm (D) chassis and is rack / tower convertible. The rail kit is not included. Net weight is 142.5 kg for the UPS and 116 kg for each battery pack, so check the cabinet's static load rating, mount everything at the bottom, and arrange proper handling before delivery day.

Can I add a second network management card or a dry-contact card?
Not in the SmartSlot. A network management card is pre-installed and it occupies the only slot, leaving zero free. Dry-contact style signalling is available instead through the maintenance bypass signal (MBS) input and the parallel port, and the unit also provides RS-232 serial, USB and a battery temperature sensor connection. If you need a free SmartSlot for an AP9613 or AP9641, that points you back to the smaller SRT models.

How does the SRTG15KXLI compare with the SRTG20KXLI?
They share the same chassis, weight, footprint, battery architecture and management. The SRTG20KXLI adds 5,000 W of capacity (20,000 VA / 20,000 W) for the same 7U and 142.5 kg, but it needs a heavier supply (87 A maximum input current and 125 A switching capacity versus 66 A and 100 A) and dissipates more heat (3,821 BTU/hr versus 2,866). Its runtime is correspondingly shorter at full load: 3 minutes 30 seconds versus 5 minutes 30 seconds. Since the footprint is identical, take the 20 kVA unit if the electrical supply and the cooling support it.

Is the SRTG15KXLI covered by warranty in Singapore?
Yes. Every APC SRTG15KXLI sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the SRTG15KXLI with a 3-year manufacturer warranty on the UPS (repair or replace, excluding the battery) and 2 years on the battery.
