Professional Installation Requirements
  • Must be installed and commissioned by a licensed electrical contractor in accordance with PSS instructions and AS/NZS 3000. This is a hardwired mains-voltage device; isolation, source synchronisation, phase sequence and neutral/earth arrangements must be verified before energisation. PSS warranty terms state that hardwired products must be commissioned by an approved and authorised PSS technician or contractor.

Applications
  • External maintenance bypass for PSS PMU-20 UPS systems
  • External maintenance bypass for PSS EP20 UPS systems
  • UPS servicing, replacement and isolation without planned interruption to critical loads
  • Power continuity installations in data centres, healthcare, industrial and commercial facilities
Standards & Compliance
  • Installation should comply with AS/NZS 3000:2018 Electrical installations, commonly known as the Wiring Rules. ([standards.org.au](https://www.standards.org.au/flagship-projects/wiring-rules?utm_source=openai))
  • The switching equipment category is associated with AS/NZS IEC 60947.3 for switches, disconnectors and switch-disconnectors; confirm the product-specific declaration of conformity with PSS. ([files.conorbriggs.com.au](https://files.conorbriggs.com.au/AS_NZS%203000_2018%20Wiring%20Rules%20--%20Standards%20Association%20Of%20Australia_%20Joint%20Technical%20--%206%2C%202018%20--%20SAI%20Global%20Pty%20Limited%20under%20licence%20from%20Standards.pdf?utm_source=openai))
