1.1 Safety notices
Symbol/sign Meaning
DANGER
This manual provides information for the safe operation of the HiPerGuard MV UPS. It does NOT
provide installation, commissioning or service information. For such information, refer to the ap-
propriate manual.
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. Many parts in
this product, including printed circuit boards operate at lethal high voltages. Stored energy compo-
nents such as batteries and capacitors can hold this voltage even after the opening of isolation
switches. DO NOT TOUCH components or connections that may have voltage present.
DANGER – High voltages
Lethal high voltages are present inside the MVM and Medium Voltage Switchgear enclosures under
normal operation or fault conditions. Do not remove any panels or guards. This may only be done by
trained technical personnel after following the stipulated isolation, grounding, and lockout proce-
dures. DO NOT TOUCH components or connections that have voltage present.
DANGER – Stored charge
Stored charge is present after the device is switched off. When the MV UPS 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. This may only be done by trained technical personnel while following
the stipulated isolation, grounding, and lockout procedures.
DANGER – Protective covers
Normal operation of this product requires all protective covers to be in place and all doors secured
closed.
DANGER – Personal Protective Equipment
Ensure safety glasses and other appropriate PPE are worn while working if any part of the unit could
be energized. Observe site requirements for PPE while operating this equipment.
Safety instructions are used to highlight a potential hazard when working on the equipment. Safety instructions
must be strictly followed! Non-compliance can jeopardize the safety of personnel, the equipment and the environ-
ment.
This manual contains important information regarding the operation of the ABB HiPerGuard MV UPS and provides
technical and operational guidance for operators. The following safety instructions are to be observed.

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. Observe any arc flash protection boundaries that may be
in place around the MVM and Medium Voltage Switchgear enclosures.
DANGER – Potential material hazard of batteries and capacitors
If a battery or capacitor is damaged electrically or physically, the resulting debris could represent a
material hazard. Refer to the appropriate Material Safety Data Sheet for information on safe han-
dling and disposal.
Safety labels are attached to the enclosures to alert personnel of potential hazards when working on the equip-
ment. The instructions on the safety labels must always be followed, and the labels must be kept in a perfectly
legible condition.

1.2 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. The operator may be authorized to provide assistance to a maintenance, service,
or repair technician, by performing his or her duties under the direction of a service team. If so, the operator must
be wearing PPE to the same level as those of the service team.
1.2.2. Before energization
Before the MV UPS is energized, inspect to make sure:
– Any maintenance work being done on the HiPerGuard has been completed and all tools and equipment
are removed.
– All covers on the HiPerGuard enclosures are securely fastened, and all doors are closed, locked, and/ or
bolted.
1.2.3. In case of fire
In case of fire in the UPS room:
– Observe the established rules and regulations for fire protection,
– Only fireman with appropriate personal protective equipment are allowed to enter the UPS room.
—
1.3 Possible residual risk
The following risks can arise from a MV UPS system and pose a hazard to
people. These risks must therefore be considered by the system integrator
and/or the plant owner when assessing the risks of the machinery.
The HiPerGuard is a high energy power conversion machine. Components may be dislodged, or damaged while be-
ing commissioned, operated or serviced, due to, for example:
– External influence on, or damage to the equipment,
– Wrong parameter settings,
– Operation of the equipment outside the scope of the specifications,
– Faulty hardware.
Any one of these faults may cause the noisy ejection of high temperature materials and gases.
Hazardous touch voltages can be present on the HiPerGuard system components caused by, for example:
– Operation of the equipment outside the scope of the specifications,
– External influence on, or damage to the equipment,
– Induced voltages by external equipment,
– Condensation on equipment components or pollution,
– Faulty hardware.
For all the above reasons, always operate with all side panels in place and all doors shut and latched.

Cyber Security
Overview
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.
For secure remote access, use a VPN connection – the HiPerGuard MV UPS is not approved by ABB for direct Inter-
net connection. The user of the product should be aware that the unsecure nature of the Modbus TCP protocol ex-
poses the communication between the product and the control system. Authentication and integrity of transmit-
ted information is not provided by the protocol. This enables certain types of attacks, such as man-in-the-middle
attacks, eavesdropping attacks and replay attacks for instance. The main security is provided through monitoring
the cybersecurity, topology (asset management) and correct operation of the data networks using the cybersecu-
rity monitoring modules and features of the firewalls and managed switches.

The ABB HiPerGuard MV UPS is a high-performance high-efficiency UPS system that ensures protection from
power quality events, enabling the continuous conditioned power supply to sensitive and critical loads.
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.
It is used to protect sensitive loads from the full spectrum of utility voltage events and combined with a wide
range of modern energy storage solutions ABB’s ZISC provides autonomies from seconds to many minutes.
The equipment is connected to the medium-voltage network through the MV switchgear. The input breaker con-
nects the power supply to the MV UPS, which also has an active role in the normal operation. The output breaker
connects the MV UPS to the load, and a bypass breaker is connected between the whole MV UPS system, as shown
in the single line diagram.
