2 DESCRIPTION
This section describes the SiteStar Cabinet.
2.1 PRODUCT OVERVIEW
The SiteStar Cabinet supports external equipment with battery backup power.
The SiteStar cabinet features an active climate solution which maximizes battery lifetime in warm climates and battery capacity in cold climates.
SiteStar cabinets are designed for both indoor and outdoor environments, with a unique combination of low thermal conductive materials and a high-efficiency climate solution. With an extremely cost-effective cooling technology and a cabinet shell that allows minimal transfer of temperatures, we keep your batteries at optimal operating temperature, with the energy usage equivalent to a single light bulb. This means the SiteStar cabinets offer up to 95% power savings compared to air-conditioned cabinets.
In case additional battery capacity is required, the SiteStar cabinet can be extended with a second SiteStar cabinet.
The system is approved for operation throughout the world. For areas exposed to earthquake risk, the Earthquake Zone 4 Cabinet version shall be considered.

2.2.1 CABINET
The cabinet structure consists of an inner and an outer liner. The volume between the liners is filled with foam insulation. With this design there is virtually no heat-bridges in the climate insulation and thus giving the cabinet an excellent thermodynamic performance.
The top of the cabinet is provided with four M8 threaded holes that are provided for the usage of lifting eye bolts.
The roof of the cabinet is designed with a small overhang in the front to protect the top of the environmental seal from direct sunlight and water.
2.2.2 EARTH GROUNDING
The cabinet is equipped with earth grounding points as follows:
Cabinet without EQ Zone 4 Reinforcement
The cabinet is equipped with a double M8 earth point at each side of the plinth, “A” in the figure below, for connection to site earth grounding point.
Figure 3 Earth Grounding in Cabinet without EQ Zone 4
Reinforcement
The PE wire of the incoming AC feed (if any) is terminated in a green/yellow PE terminal located inside the CF, securely connected to the cabinet ground.
EQ Zone 4 Cabinet
The cabinet is equipped with four earth grounding studs in the bottom of the cabinet, Figure 4, for connection to site earth grounding point.

Locking System
Doc. No: D000100-INS-01, Rev I Page 11 of 35
2.2.3.1 CLIMATE CONTROL UNIT
The Climate Control Unit (CCU) is monitoring the temperature inside the cabinet and regulates the Climate Unit (CLU).
The external alarm interface on the CCU is wired to the Connection Field, which includes the interface for the outgoing external alarm cables.
The control unit and its panel are located at the inside of the bottom part of the door.
Figure 5 shows the panel. The panel also exists with an ECO indicator and switch, see Figure 6.
Fault indicator is red, Operational green and Information yellow.

Doc. No: D000100-INS-01, Rev I Page 14 of 35
2.2.4.2 DC CONNECTION UNIT
In cabinets with DC powered CLU the batteries and the CLU can be connected direct to an external power supply unit or through the optional DC Connection Unit (DCCU).
The DCCU is a connection point, including fuses, for up to 4 battery strings.
Cable lugs for cables up to 95 mm2 can be used with the DCCU. All connections are M8 studs and the distances between the studs are 1 inch. The DCCU is installed at the bottom of the cabinet, Figure 8.
For further information, see D000108, SiteStar DCCU Kit.
Figure 8 DCCU
Warning!
If the SiteStar cabinet is configured without the DCCU, it is of vital importance that the Battery cables are provided with adequate protection at the site to ensure compliance to national wiring regulations.
It is recommended to use SiteTel Cables to ensure a safe connection.
Risk of personal injury and property damage.
Doc. No: D000100-INS-01, Rev I Page 15 of 35
2.2.4.3 CLU POWER CONNECTION TERMINAL
The cabinet is equipped with a CLU power connection terminal, at the bottom of the CF, for the connection of power to the CLU.
2.2.4.4 CIRCUIT BREAKER
The Circuit Breaker (CB) is located at the same DIN rail as the CLU power connection terminal.
2.2.4.5 SURGE PROTECTION DEVICE
The CF can include an optional Surge Protection Device (SPD) hardware to protect the CCU from over voltage.
The SPD is located at the same DIN rail as the CLU power connection terminal.
2.2.4.6 EXTERNAL ALARM CONNECTION
The system supports sending 3 external alarms. The alarms are sent by relays, connected as normally closed (NC). The external alarms will be trigged by:
CLU failure: fan fail or controller fail
Temperature: Internal temperature outside regulation window or external temperature outside system specification

2.6 CLIMATE SYSTEM
This section describes the climate system.
2.6.1 GENERAL
The cabinet features a climate system including heating and active cooling systems. The system ensures maximum battery life in cold and warm climates.
SiteStar can be set to power-up and operate in one of two modes:
Normal Operational Mode
Factory Test Mode
Doc. No: D000100-INS-01, Rev I Page 25 of 35
The mode is selected when the system is powered up based on the state of the door switch. Normal Operational Mode is selected if the door switch is open when the power is switched on and Factory Test Mode if the door switch is closed.
2.6.1.1 NORMAL OPERATIONAL MODE
In Normal Operational Mode the system operates as follows:
Power-up
When the system is powered up in Operational mode, it will automatically initiate the SW’s start-up sequence.
Self-test
The system does a self test at start-up. The start-up sequence is up to 2 minutes long. During the self test, all components in the system are tested, i.e. compressor, fan, heater (if equipped), temperature sensors, etc. The yellow indicator is lit during the self test sequence. After the self-test is completed the system will go into operation mode, or indicate a fail. As the system goes into operation, the yellow indicator will go out, and the green ‘Operational’ will be lit.
Power-up
•SW initiation
Self test
•Module test
•Relay test
•Indicator test
Operation
•Temperature regulation
ECO Operation
•ECO operation (if available)
Doc. No: D000100-INS-01, Rev I Page 26 of 35
After approximately 1 minute in operation mode, Door Alarm is activated. The alarm is revoked 1 minute after closing the door.
Operation
After the system has completed the self test sequence the system will start to regulate the temperature inside.
If necessary the system can be equipped with a heater. If so, the system will remain the optimum temperature for the batteries in sub zero temperatures down to -40 °C.
ECO Operation
Some SiteStar systems have an ECO Operation mode. This mode will reduce power consumption up to 20%.
Fail
The following fails can be detected:
Compressor fail
Temperature sensor fail
Fan fail
Internal Heater fail (if equipped)
Over temperature, inside
Under temperature, Inside
Over temperature, outside
2.6.1.2 FACTORY TEST MODE
Factory test mode is only used during factory test before delivery to site and should not be used when the system is installed on site due to long test cycle.
In Factory test mode the factory technicians can carefully test the system temperature regulation function.
No alarm indications or external alarms are activated in this mode.
2.6.2 TEMPERATURE REGULATION
In normal operation mode the temperature can vary between 21 °C and 24 °C.
In ECO mode the temperature can vary between 10 and 27 °C.
Doc. No: D000100-INS-01, Rev I Page 27 of 35
If the ambient temperature, Ta, is above +55°C the temperature alarm will be active. .
The cooling system has the following protective functions:
Reduced running time for the compressor at high temperature
Automatic de-icing
Thermal shut down of compressor

To force the compressor to run, the inside temperature needs to be above 24 °C (in normal operation) or 25 °C (in ECO Operation)
If the outside temperature is too high, the running time of the compressor is reduced to approx 30% (9 minutes running/25 minutes resting)
