1. Overview
The LS 51.3V / 166F Ultracapacitor Module has high energy and low ESR to meet
energy storage and power delivery requirements.
The cells used in the module have 2.85V maximum voltage rating and are connected in
series to get higher operating voltage of modules. To meet the long cycle life
requirements, the cells operate under 2.85V. In addition, all the cells are balanced by
balancing circuit connected parallel to each cell.

3. Unpacking
Inspect the shipping carton for signs of damage prior to unpacking the module.
Damage to the shipping carton or module should be reported to the carrier 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.
NOTE: The original shipping materials are approved for both air and ground shipment.
The module should be removed from the shipping carton by lifting the body of the
module.
4. Safety
- Do not operate above specified voltage.
- Do not operate above specified temperature rating.
- Do not touch terminals with conductors while charged. Serious burns, shock, or
material fusing may occur.
- Protect surrounding electrical components from incidental contact.
- Provide sufficient electrical isolation when working above rated voltage.
- Prior to installation and removal from the equipment, it is mandatory to fully discharge
the module.

6. Output terminal connection
The LS 51.3V / 166F Ultracapacitor Modules are designed to connect directly to a
ring or a bus bar. The positive and negative terminals have each hole for the screw.
The positive terminal threaded size is M8 and negative terminal is M10. Wave
washers are required to ensure long term, reliable connections.
When tightening the terminal bolt, a torque of 20 N-m for the M8 bolt should be
used.(30N-m for the M10 bolt) Because the modules have a very low ESR, total ESR
will be affected by a ring lug, bus bar or torque. Therefore, it needs more attention to
assemble the modules. And appropriate protection and sealing should be used on
both module terminalsto avoid shock hazardsand corrosion.

Pin 4 is connected with monitoring connector output signals receiver circuit’s ground.
The output signals are isolated from the capacitor voltage and from chassis ground.
The recommended voltage is 5V DC.
When a cell in the module goes into over voltage condition, pin 3 has alarm signal.
When every cell voltage is not over voltage state, the output of Pin 3 is high. If any cell
in the module is exceeding normal voltage, the voltage balancing circuit becomes
active and starts to discharge the cell to become normal voltage range. Then the
output of Pin 3 goes low. At this time, user should stop charging. However, in order to
use the signal, the user needs to attach a pull-up resistor(typically 1kΩ) to pin 3 and a
5V supply.
When the cell voltage is below the threshold, the output of Pin 3 goes high. And if the
cell voltage is drop more, the balancing circuit becomes inactive and the cell stop
discharging.
It is possible that the output of Pin 3 is indicated by LED. The output signal receiver
circuit is as following.
<Fig. 5> Typical output signal receiver circuit to the Output connector
Pin 1-2 are connected with a PTC thermistor for temperature monitoring.According to
temperature variation in the module, the resistance of the thermistor is determined.
The resistance is approximately 470Ω±50% , when the internal temperature in the
module is 25 ℃.

<Fig. 6> Mounting Positions
8. Mounting
The modules should not be mounted in locations where they are directly exposed to the
environment.
- <Fig. 6> shows the mounting positions of the module.

9. Maintenance
Power Rating
If the applied voltage is over rated voltage, charging the module should be stopped.
And the allowable low voltage level of the module depends on the user’s requirements,
but full discharging to 0V does not affect the module performance.
Temperature
The module has its optimal operating temperature range of -40 to 65. Over 70℃,
charging and discharging should be stopped to preserve its performance and life cycle.
Do not expose to direct sunlight
For installation do not make the module expose to direct sunlight due to temperature
increase inside the module.
Maintenance
The module has its projected life over 10years at rated voltage and +25℃. However
the life cycle of the module may be decreased in high temperature condition or over
voltage charging.
If following abnormal module performances are detected, operation should be stopped
and checking the electrical & mechanical connections is recommended.
- Detection of high temperature in normal operating conditions
- Internal resistance increase or initial voltage drop increase
- Deformation of the module case
