Which UPS models does the SRTG192XLBP4 fit?

Schneider's installation guide SUO-IM-990-91417-EN names the compatible models explicitly, and the list is exactly four:

The SRTG192XLBP4 is not compatible with the SRTG15KXLI or SRTG20KXLI, which run on a ±192 V bus and take the SRTG192XLBP2. Nor is it compatible with the older Smart-UPS SRT range: despite the “192V” in their names, the SRT192BP, SRT192RMBP, SRT192BP2 and SRT192RMBP2 are different packs with a different connector and a different replacement cartridge (APCRBC140 rather than APCRBC174). Order by part number.

Maximum four packs. Schneider's UPS manuals state that up to four external battery packs can be connected to the SRTG 5–10 kVA UPS in parallel. The ten-pack figure belongs to the smaller Smart-UPS SRT models and must not be carried across when sizing an SRTG installation. Packs connect to the UPS battery input and to one another with the supplied 0.64 m battery cable — the installation guide has you swap the connector holder on the cable to link one pack to the next.

Runtime. Runtime is not linear — halving the load more than doubles the time on battery. Schneider publishes the pack's cell count and capacity rather than a minutes-per-load table for each UPS and pack combination, so rather than quote a runtime we cannot source, ask SourceIT for a calculation against your measured load, your pack count and your generator start time. As reference points from Schneider's range brochure, the SRTG10KXLI alone runs approximately 3 minutes at full load and 10.5 minutes at half load, and the SRTG8KXLI approximately 4.5 minutes and 13 minutes.

Rack fit and weight. Each pack occupies 3U in a 131 mm (H) x 440 mm (W) x 680 mm (D) chassis and weighs 83.5 kg with batteries installed. The rail kit is not included — Schneider's product page lists the SRTGRK1 for this pack, the same kit used for the UPS itself; the SRTGRK2 is the kit for the SRTG192XLBP2 pack on the 15 and 20 kVA systems. A 5 kVA UPS with two packs is 10U and roughly 223 kg; a 10 kVA UPS with four packs is 17U and roughly 436 kg. Confirm the cabinet's static load rating, the floor loading and the delivery route with building management before ordering, and mount the packs at the bottom of the cabinet with the UPS directly above them.

Cables and hardware. The SRTG192XLBP4 includes its 0.64 m battery cable and connector holder, a 0.74 m ground cable, a pair of rack-mount brackets, two pairs of stabiliser brackets with six connectors, four M5 floating nuts, four M5 x 12 Phillips screws and four M4 x 6 flat-head screws. The one thing you must order separately is the rail kit.

In the box (Schneider installation guide): front bezel x1; M5 floating nuts x4; M4 x 6 flat-head screws x4; M5 x 12 Phillips screws x4; battery connector holder x1; ground cable 0.74 m x1; battery cable 0.64 m x1; stabiliser brackets 2 pairs with 6 connectors; rack-mount brackets 1 pair; installation manual x1; packing list x1. The rail kit is not included.

Which UPS models does the SRTG192XLBP4 fit?
Four: the SRTG5KXLI, SRTG6KXLI, SRTG8KXLI and SRTG10KXLI. Schneider's installation guide names them explicitly and lists nothing else, and Schneider's own product description reads "192V SRTG Battery pack for 5kVA/6kVA/8kVA/10kVA SRTG On-Line UPS". It does not fit the SRTG 15 and 20 kVA units, which take the SRTG192XLBP2, and it does not fit the older Smart-UPS SRT range.

What is the difference between the SRTG192XLBP4 and the SRTG192XLBP2?
Everything except the "192V" in the name. The XLBP4 is thirty-two 5 Ah cells on a ±96 V bus in a 3U, 83.5 kg chassis with the APCRBC174 cartridge, for the 5–10 kVA units. The XLBP2 is a 9 Ah pack on a ±192 V bus in a 4U, 116 kg chassis with the APCRBC172 cartridge, for the 15 and 20 kVA units. The bus voltages differ, so the wrong pack cannot be used even if it were physically connected. Order against the UPS part number you own.

How many SRTG192XLBP4 packs can I connect?
A maximum of four, connected in parallel and daisy-chained pack to pack with the supplied battery cable. This is the figure Schneider's UPS manuals state for the SRTG 5–10 kVA units. The smaller Smart-UPS SRT models accept up to ten packs, and that figure is often carried across by mistake — do not design to it.

How much runtime will one pack add?
That depends entirely on the load, and runtime is not linear — halving the load more than doubles the time on battery. Schneider publishes the pack's cell count and capacity rather than a minutes-per-load table for each combination, so rather than quote a runtime we cannot source, ask SourceIT for a calculation against your measured load, your pack count and your generator start time. As a reference, the SRTG10KXLI alone runs approximately 3 minutes at full load per Schneider's range brochure.

Which replacement cartridge does the pack take?
The APCRBC174 — the same cartridge Schneider lists for the SRTG 8 kVA and 10 kVA UPS, which simplifies spares holding if you run those units. The batteries are sealed maintenance-free VRLA, 32 x 12 V 5 Ah cells in four modules, all installed from the factory. Plan on replacement every three to five years; heat is the main determinant, so a cabinet held near 25 °C will get materially more life than one at 35 °C.

How much rack space does it need, and is the rail kit included?
3U per pack, in a 131 mm (H) x 440 mm (W) x 680 mm (D) chassis, and the rail kit is not included. Schneider's product page for this pack lists the SRTGRK1 — the same kit as the UPS — ordered separately. The pack is rack / tower convertible and the stabiliser brackets for tower use are in the box. Each pack weighs 83.5 kg with batteries installed, so a 10 kVA UPS with four packs is 17U and roughly 436 kg. Check the cabinet's static load rating and the floor loading with building management before ordering.

What is in the box?
Front bezel, four M5 floating nuts, four M4 x 6 flat-head screws, four M5 x 12 Phillips screws, the battery connector holder, a 0.74 m ground cable, a 0.64 m battery cable, two pairs of stabiliser brackets with six connectors, one pair of rack-mount brackets, the installation manual and a packing list. The battery cable and mounting hardware are included; the rails are not.

Is the SRTG192XLBP4 covered by warranty in Singapore?
Yes. Every APC SRTG192XLBP4 sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the SRTG192XLBP4 with a 2-year manufacturer warranty on the batteries.
