2.4 System Components

The Aspiro system is delivered with all components mounted according to the ordered
conguration. The main components are described below and in later chapters of the manual.
There are 2 versions of Aspiro shelf available depending on the value of battery current shunt used: 20 A or 80 A.
CAUTION Low Power Shelf version (20 A version) provides better resolution for battery current reading and it is suitable for low power applications with maximum battery charge current less than 5A.

2.4.1 System Controller

The Aspiro power system can be controlled by the ACC Extended or PCC controller. The description and operation of these controllers is covered in separate manuals which are available at:
ACC Extended: http://www.unipowerco.com/pdf/acc-man.pdf
PCC: http://www.unipowerco.com/pdf/pcc-man.pdf

2.4.2 DC Distribution

DC Distribution consists of maximum 1 battery and 4 load breakers available in a variety of sizes.
The distribution unit is designed for switching the battery and load on and o.
The battery and load breakers are supervised by measuring the voltage drop across each breaker. In the case of load breakers, those which are not connected to any load will not cause a breaker alarm even if they are left open.
A battery fuse alarm is generated after the battery voltage drops below a certain level, depending on the actual battery capacity and condition.
Low Voltage Disconnect (LVD)
The system is equipped with a low voltage battery disconnect which prevents the batteries from deep discharging, thus prolonging the battery life. The disconnect requires a detected mains failure at the supervision unit (controller).
If disconnection occurs, the batteries will not supply power to the load until they have been recharged to a set voltage level, which can be adjusted by the user.
If disconnection occurs, the batteries will be reconnected when the mains supply returns.

2.4.4 Rectier Module
The Fan-Cooled XPGe12.48 (1200W), XR08.48 (800W) and XR04.48 (400W) rectiers
are modular power supplies designed for parallel operation and hot-plug installation in the Aspiro Power Systems.
Each rectier provides extremely reliable DC power in a very high density. The module
incorporates power monitoring through an internal microprocessor, giving up to the
second updates to the system controller and companion rectiers. This guarantees tightly controlled load sharing among rectiers, and provides status and identication
information to the controller.
The rectiers operate in parallel using active load sharing. They incorporate soft-start
at both the input and the output, which protects against high incoming and outgoing
currents. The output voltage of the rectier is automatically adjusted to the required
voltage by the controller.
XPGe12.48 rectiers cannot be used in the same rack as XR04.48 / XR08.48 rectiers.
CAUTION XPGe12.48 rectiers cannot be used in the same system as XR04.48/ XR08.48 rectiers.

Chapter 3 System Safety

3.1 Safety Warnings and Guidelines

The following warnings and guidelines should be followed by properly trained and authorized personnel when installing, operating, commissioning or maintaining this equipment. Neglecting the instructions may be dangerous to personnel and equipment.

3.1.1 System Markings

The following markings are found on the Power System:
Ground Symbol
DC Ground Symbol
Product Label - The product label contains the system part number, model number, system
ratings and safety approvals. The label is located on the left side of top cover.

3.1.2 Safety Recommendations

Any device that uses electricity requires proper guidelines to ensure safety.
• The Power System should only be installed or serviced by a qualied personnel.
• Always keep tools away from walkways and aisles. Tools present a tripping hazard
in conned areas.
• Keep the system area clear and dust-free during and after the installation.
• Always know the location of emergency shut-o switches in case of an accident.
• Always wear appropriate eye protection and use appropriate tools for working with high voltage equipment.
• Do not perform any action that creates a potential hazard to other people in the system area.
• Never work alone in potentially hazardous conditions.
• Always check for possible hazards before beginning work.
• Remove watches, rings and jewelry that may present a hazard while working on the power system.

POWERING TECHNOLOGY

3.1.3 Installation Warning

The following safety guidelines should be observed when transporting or moving the system:
• Before moving the Power System, read the system specications sheet to determine whether the install site meets all the size, environmental, and power requirements.
• The system and the equipment included, should only be moved and installed by
qualied personnel to prevent bodily injury or any other hazardous conditions.

3.1.4 Restricted Access Area Warnings

The Power System is designed for installation in locations with restricted access often secured by a locking mechanism. It can therefore be accessed only by a trained service person, who is fully aware of the restrictions applied to the location, or by an authority responsible for the location.

3.1.5 Electrical and Fire Enclosure

The unit is for building-in. A suitable Electrical and Fire enclosure shall be provided.

3.1.6 System Enclosure

Appropriate measures need to be taken to avoid intrusion of any unwanted objects or insects into conductive areas of the power system as there is a potential risk of system damage.
Disclaimer: UNIPOWER LLC assumes no liability or responsibility for system failures resulting from inappropriate enclosure around the system.

3.1.7 Operating Temperature Warnings

To prevent the Power System from overheating, an automatic shutdown mechanism has been installed. It is not recommended to continually operate the Power System in an area that exceeds the maximum recommended operating temperature.

3.1.8 Electrical Safety Warnings

The following are electrical safety recommendations for working near the Power System:
WARNING Observe low voltage safety precautions before attempting to work on the system when power is connected. Potentially lethal voltages are present within the system.
