Three-Phase UPS Installation | Brisbane Sydney Melbourne
Licensed three-phase UPS installation for data centres, hospitals, mining sites and large industrial loads, 10kVA to 2MVA.
UPS Services installs three-phase UPS systems for Australian data centres, hospitals, mining sites, telco facilities and large industrial loads. We work across the full kVA range (from 10kVA modular up to 2MVA standalone) and can specify, install, and commission single-module, parallel, and N+1/2N redundancy configurations.
Three-phase installations involve switchboard-side work, neutral conductor sizing, phase balancing, and external maintenance bypass design, all delivered by licensed electricians under AS/NZS 3000. Battery cabinets and lithium-ion battery systems are specified to AS/NZS 5139.
We supply and install all major three-phase UPS brands: APC Galaxy VS / Galaxy VL, Eaton 9395 / 93PM, Vertiv Liebert APM2 / Trinergy / EXL S1, PowerShield Centurion Pro / Modular, Socomec MASTERYS, with manufacturer-trained technicians.

Frequently asked questions
4 questions answered.
Q01
What is the difference between modular and standalone three-phase UPS?
Modular UPS systems use hot-swappable power modules in a single frame (typically 25kW or 50kW each), allowing pay-as-you-grow scaling and faster MTTR (mean time to repair). Standalone three-phase UPS uses a single fixed capacity tower and is generally lower CapEx for a known load. For data centres with variable growth, modular is usually the better long-term choice.
Q02
Do I need an external maintenance bypass panel?
Yes: for any three-phase UPS, an external maintenance bypass panel (MBP) is essential to allow servicing without dropping the load. The MBP is a make-before-break switching panel that lets technicians isolate the UPS for battery replacement, firmware updates, or fault investigation while critical loads continue running on raw mains power.
Q03
Can you commission UPS to manufacturer warranty requirements?
Yes. Manufacturer-trained commissioning is mandatory for warranty validation on most three-phase UPS systems (APC Galaxy, Eaton 9395, Vertiv Liebert APM2, etc.). Our commissioning engineers hold current factory training and provide the manufacturer commissioning sign-off required to activate full warranty coverage.
Q04
How do you size redundancy?
Redundancy is sized against your tier classification (Uptime Institute Tier I-IV) and acceptable downtime tolerance. Typical configurations: N (no redundancy) for Tier I, N+1 (one spare module) for Tier II/III, 2N (full dual-bus) for Tier IV / mission-critical. We can advise on the right sizing during the design phase.
