Professional Installation Requirements
- Installation, external battery connection and commissioning must be performed by an appropriately licensed electrical contractor or approved UPS technician. The system should be installed in accordance with the manufacturer’s instructions, AS/NZS 3000 and applicable UPS safety requirements. External battery banks, isolation, bypass equipment, cabling, ventilation and protection must be designed for the site load and battery arrangement.
Applications
- Data centres and server rooms
- Telecommunications and network infrastructure
- Medical and healthcare facilities
- Industrial control and automation systems
- Mining and remote industrial sites
- Security, surveillance and access-control systems
- Manufacturing and process-critical equipment
- Critical loads requiring extended runtime from external batteries
Standards & Compliance
- AS 62040.1: Uninterruptible power systems safety requirements
- AS/NZS 3000: Electrical installations and wiring requirements for hardwired UPS installation
- AS IEC 62040.2: Applicable UPS electromagnetic compatibility requirements
- AS IEC 62040.3: UPS performance specification and test requirements
Environmental Benefits
- External battery architecture allows battery capacity and runtime to be sized to the application, avoiding unnecessary battery material and replacement waste
- Transformer-based design supports reliable operation over a broad range of critical loads, potentially extending equipment service life
- Optional harmonic filtering and generator-optimised operation can reduce upstream electrical losses and improve system efficiency
- Lead-acid battery banks, where used, are recyclable through established battery recovery systems
