    Stored charge is present after the device is switched off. When the HiPerGuard is powered down, lethal voltages will remain in the energy storage elements and the complete HiPerGuard MV UPS should be considered live. To remove this hazard, energy storage will need to be isolated and locked off, and filter capacitors discharged.

    S A FET Y 1.2. General safety information 1.2.1. Operator duties The scope of work for an operator of the HiPerGuard is to control and monitor the HiPerGuard from the GDM, remote start/stop controls, or from the web page. An operator is not normally authorized to undertake any maintenance, service, or repair work.

  • Page 19: Cyber Security Legal Disclaimer

    2.1. Deployment guidelines The recommended Cyber Security deployment for the HiPerGuard MV UPS is for it to be only used in a trusted network with restricted access. The user is responsible for creating a defense-in-depth protection by allocating firewall solutions to each network.

  • Page 20: Product Description

    Based on the ZISC (Impedance Isolated Static Converter) architecture, the HiPerGuard MV UPS uses a special coupling reactor combined with PEBB120 inverter modules to interface from the utility to the load.

  • Page 21: Operating Principle

    The resulting performance is continuous clean power in accordance with IEC62040-3 VI SS 111. The efficiency is greater than 98% for the load spectrum from 50% up to rated full load. When operating on the Power Conditioning mode, the HiPerGuard MV UPS can supply high fault currents for downstream protection.
  • Page 22 3.2.2. Independent mode If the utility power is no longer available or in a prolonged sag event, the HiPerGuard MV UPS opens the input circuit breaker and transfers the load to the energy storage, operating now in Independent mode. The energy storage allows ride-through time for either the utility power to be restored or for the time necessary for an alternative energy source to be activated, such as a generator, for example.
  • Page 23 P RO DU C T D ES C R IP T I ON The input breaker management graph is split into two regions. The first part, a slow filter curve down to 50% input voltage, is designed for thermal management of the MV UPS and protection coordination. It allows the MV UPS to keep the input circuit breaker closed for typically 1 second at 50%.
