Introduction
The Sirius Capacitor Module (“Sirius”) is supercapacitor-based storage that uses supercapacitors as
storage cells instead of chemical cells. Kilowatt Labs’ proprietary balancing, control and charge
retention algorithms control the operation of the supercapacitor-based modules, making Sirius a safe,
efficient and effective alternative to chemical batteries wherever chemical batteries are deployed.

F12 terminals
Terminals
1. Circuit Breaker:
Circuit breaker is used to power ON the Module. It also acts as a second line of protection, if the circuit
fails to protect the Module from over current, the circuit breaker will trip.
2. Bypass Circuit Breaker:
The Bypass Circuit breaker is used to bypass electronic switch. It is used for Series connection and
recovery of the Module.
3. Fault Reset:
Fault Reset is a push button which is used to turn ON the protected terminal manually after it turns
OFF due to any error.
The additional features of fault reset are as follows:
a) Hold fault reset for 5 seconds to toggle the protected terminal.
b) Hold fault reset for 3 seconds to reset fault if there is/are any.
c) We can set the Current reading to zero.
d) Press fault reset button to check the state of charge and instantaneous power.
e) Press the fault reset button to see the individual cell voltages.
•Checking for individual Cell Voltages:
When the fault reset button is pressed, the LCD after displaying the state of charge (SOC) and
instantaneous power, will display the cell voltages of the first four cells as shown below:
Whereas:
01=Voltage of 1st Cell
02=Voltage of 2nd Cell
03=Voltage of 3rd Cell
04=Voltage of 4th Cell
By continuously pressing, the cell voltages will be displayed for all the cells.
•Enabling/disabling Cell balancing:
After scrolling through the individual cell voltages, cell balancing can be enabled/disabled by the
following steps below:

Step 2: After this message appears, hold fault reset button for 5 seconds, then the LCD will display the
following message which means that the cell balancing has been enabled.
Step 3: To disable cell balancing, when current is zero, the LCD will display the following message.
Step 4: After this message appears, hold the fault reset button for 5 seconds, then when the LCD
displays the following message, it means that balancing has been disabled.
Step 5: To make the current zero, follow the steps below:
→When current is not zero, the LCD will display the following message.

9. F12 Terminals:
These are the output terminals of the Module having electronic switch protection that is limited to
100VDC only. F12 terminals are used to connect the load or charger to the Module. There are also
positive and negative cables in the jumper cable set. The red one is positive (+), the black one is
negative (-).
3. Module Installation:
3.1 Inspection:
Inspect the shipping carton for visible damage including cracks, dents, deformation and other visible
abnormalities prior to unpacking the Module. Document (photograph) any damage and report this to
your Reseller as well as to the shipping agent immediately. Remove the Module from the shipping
carton and retain the shipping materials until the unit has been inspected and is determined to be
operational.
3.2 Safety Gear:
Installation must strictly follow the national safety regulations in compliance with the enclosure,
installation, creepage, clearance, casualty, markings and segregation requirements of the end-use
application. Installation must be performed by professional installers only. Switch OFF the system and
check for hazardous voltages before altering any connection! Sirius Modules must be handled only by
qualified and trained personnel. Installation should not exert bending or twisting torque to the Module
enclosure.
