Page 16: Safety Notices
CAUTION – Trained operators All operations on the HiPerGuard MV UPS must only be carried out by a trained operator familiar with the contents of this manual. Hazardous conditions could arise from incorrect adjustment. DANGER – Hazardous voltages An Operator must not open doors or panels marked as containing hazardous voltages. - Page 17 DANGER – Arc flash Arc flash is a dangerous phenomenon associated with operation at medium voltages. It may be caused by switchgear failure, insulation breakdown or foreign object intrusion. It may result in se- vere burns, severe eye injury, blindness, or death. To minimize the risk, keep all doors closed and cov- ers in place while operating the equipment.

Page 18: General Safety Information
1.2.1. Operator duties The scope of work for an operator of the HiPerGuard MV UPS is to control and monitor the MV UPS from the GDM, remote start/stop controls, or from the web page. An operator is not normally authorized to undertake any main- tenance, service or repair work. -
Page 19: Cyber Security
2.1 Deployment guidelines The recommended Cyber Security deployment for the HiPerGuard MV UPS is for it to be only used in a trusted net- work with restricted access. The user is responsible for creating a defense-in-depth protection by allocating fire- wall solutions to each network. -
Page 20: Product Description
Based on the ZISC (Impedance Isolated Static Converter) architecture, the HiPerGuard MV UPS uses a special cou- pling reactor combined with new generation PCS120 power modules to interface from the utility to the load. The reactor acts as a barrier, preventing grid disturbances to reach the load and improves the power factor seen from the grid side. -
Page 21: Operating Principle
— 3.2 Operating principle The HiPerGuard MV UPS has two modes of operation: Power Conditioning and Independent mode. In the Power Con- ditioning mode, the MV UPS supplies continuously regulated voltage, irrespective of utility conditions. The high-performance power electronic inverters ensure that the output voltage is regulated for combinations of in- put supply voltage disturbances. - 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 its input breaker and transfers the load to the energy storage, operating now in Independent mode. The energy storage al- lows ride-through time for either the utility power to be restored or for the time necessary for an alternative en- ergy source to be activated, such as a generator for example.
- Page 23 — Figure 3.04: Three phase under/over voltage input breaker management graph. 3.2.4 Transition from Independent to Power Conditioning mode As soon as the input voltage returns to the nominal level, the MV UPS starts the transition from the Independent to the Power Conditioning mode. A “trust period” of two seconds before the transition assures that the input volt- age is stable, avoiding unnecessary breakers operations.
- Page 24 H I P E R G U A R D M V U P S U S E R M A N U A L — Figure 3.05: MV UPS fed by an upstream generator. The MV UPS understands that the generator can handle the load when it increases the frequency back towards nominal frequency.
- Page 25 3.2.6 Automatic bypass operation In case of an expected or unexpected HiPerGuard MV UPS shutdown, the load current is transferred to the au- to-bypass breaker. The MV switchgear acts as the primary system bypass, and its operation is fully controlled by the MV UPS, while the MV UPS control switch located on the switchgear is in “UPS Control”...
- Page 26 MV UPS provides the control interface, but all the logic operations and power setpoints are provided by the DRC. The DRC is not part of the HiPerGuard's scope of supply and can be obtained from ABB or a third party supplier.
- Page 27 The HiPerGuard MV UPS can optionally be configured to prevent grid power back-feed if a DRC Power-setpoint is greater than the current load power. This is useful if the load reduces faster than the DRC can respond. This func- tion is enabled via a configurable parameter on the MV UPS.
- Page 28 The auxiliary power supply of the MV UPS during PCM and IM modes of operation is generated internally. However, an external auxiliary power supply must be available during the commissioning and servicing for starting of the HiPerGuard MV UPS. This is required for powering the main controller, precharging the DC bus, and controlling the MV switchgear.

Through the GDM, it is possible to operate the HiPerGuard, read/edit its parameters, reset alarms and faults, and access power-quality events data.
- Page 32 3.3.3 Medium Voltage Magnetics enclosure (MVM) iliary Charger) This is the medium voltage section of the HiPerGuard MV UPS that includes the coupling transformer and the line reactor. The coupling transformer connects the low voltage power converters to the medium voltage network. The isolating line reactor, which is a 50% impedance, isolates the coupler transformer and the load from the utility.

Page 52: Communication Between Mv Switchgear
6.5 Communication between MV UPS and MV Switchgear There is a high-speed optical communication link between the HiPerGuard MV UPS’s main controller and the switchgear. The purpose of the link is to read and write information from/to the I/O modules installed in the MV switchgear. -
Page 53: Modbus Tcp/Web Interfaces
It is possible to connect two or more HiPerGuard MV UPS units in a parallel configuration. The medium voltage in- put and output connections of the group are paralleled via the medium voltage switchgear. This enables the MV UPS system total output power capacity to be increased according to the number of units in parallel, and to achieve redundancy in the event of a fault with one of the units. - Page 54 The Figure 6.11 shows n HiPerGuard MV UPS units connected in parallel. Note that two network switches are re- quired (not included on MV UPS scope of supply), each with enough Ethernet ports to support the number of units in parallel.

Page 55: User Interface
The primary user interface for configuration of the HiPerGuard MV UPS is via the Graphic Display Module (GDM) which is mounted on the door of the PE120-1 enclosure. It allows local control of the HiPerGuard MV UPS and shows the system status and provides access to the operating parameters and event history. - Page 56 H I P E R G U A R D M V U P S U S E R M A N U A L Below the status bar, there is a symbol that indicates the MV UPS health with event code that displays the highest priority.

Page 83: Maintenance Schedule
The recommended intervals for maintenance and component replacement are based on the normal operating conditions of the HiPerGuard MV UPS.
