Unpacking the Batteries
When received, the batteries should be inspected. Make
sure the batteries were not damaged during transport, and
that all the proper accessories were included in the delivery.
If problems arise, please initiate a claim immediately.
Note: * indicates where further information can be
found in the NSB UPS Application Manual. Warnings
and notifications can be found on the label (shown
below) which appears on each product. Be aware and
adhere to all warnings which appear on the product
torque value printed on the battery label. *(Commissioning/
Installation 10.9)
8. The insulation covers should be put back after all
connections have been completed.
*( Commissioning/Installation 10.10)
9. It is highly recommended to give the batteries a refreshing
charge prior to commissioning. Failure to observe these
conditions may result in greatly reduced capacity and service
life. *(Charge 10.14)
Charging Regime Prior to Qualification Testing
Contains: Lead, Sulfuric Acid (Electrolyte), Lead Compounds, Arsenic
Ensure reference materials are reviewed and made available to all operators
including application manual, installation guide, and MSDS.
Case 1)
For batteries that have a date code older than 6 months:
a. Equalization charge the battery strings at 2.41vpc for
four hours
b. Reduce voltage to 2.35vpc for eight hours
c. Reduce voltage at battery to 2.27vpc and float for at least
four hours to let all the gas generated during
charging recombinate.
Harmful if swallowed, inhaled, or in contact with skin.
Acid causes severe skin burns and eye damage.
May damage fertility or the unborn child if ingested or inhaled.
May cause harm to breast-fed children.
May cause cancer if ingested or inhaled.
Causes skin irritation, serious eye damage.
Contact with internal components may cause irritation or severe burns.
Causes damage to central nervous system, blood and kidneys through prolonged
or repeated exposure if ingested or inhaled.
Irritating to eyes, respiratory system, and skin.
May form explosive air/gas mixture during charging.
Obtain special instructions before use.
Do not handle until all safety precautions have been read and understood.
Wash thoroughly after handling.
Do not eat drink or smoke when using this product.
Avoid contact during pregnancy/while nursing.
Wear protective gloves/protective clothing, eye protection/face protection.
Use only outdoors or in a well-ventilated area.
Avoid contact with internal acid.
Do not breathe dust/fume/gas/mist/vapors/spray.
IF SWALLOWED OR CONSUMED: rinse mouth. Do NOT induce vomiting. Call a
poison center/doctor if you feel unwell.
clothing and wash it before reuse. Rinse skin with water/shower.
IF INHALED: Remove person to fresh air and keep comfortable for breathing.
Immediately call a POISON CENTER or doctor/physician.
IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses,
if present and easy to do. Continue rinsing.
If exposed/concerned, or if you feel unwell seek medical attention/advice.
Store locked up, in a well-ventilated area, in accordance with local and
national regulation.
Dispose of contents/container in accordance with local and national regulation
Keep out of reach of children.
PROPOSITION 65 WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Batteries also contain other
chemicals known to the State of California to cause cancer. Wash hands after handling.
ºC or incinerate. Not recommended for inverted use. Follow product charging instructions.

Case 2)
For batteries that have a date code less than six months:
a. Refresh/Boost charge the battery string at 2.35vpc for
twenty-four hours
b. Reduce voltage at battery to 2.27vpc and float for at least
four hours to let all the gas generated during
charging recombinate.
1. Before proceeding with the installation of the battery,
review or determine the arrangement of the batteries for
the application.
10. The optimum level for float charging the NSB UPS
batteries is 2.27 volts/cell at 25°C (77°F). *(Charge 2.2)
Example: 40 battery string = 544.8V
Example: 32 battery string = 435.8V
2. Checking the voltage spread is vital before connecting
the monoblocks in series. Refer to section 10.2 for more
3. If installing multiple parallel strings, the cabling to each
string should be the same size and approximate length
resulting in the same resistance per string.
*(Battery Connection to Load/Charger 10.12)
11. If the ambient temperature increases above 25°C (77°F),
a thermal compensation of -2 mV/cell/°C is recommended.
Conversely, if the temperature decreases below 25°C (77°F),
the voltage should be increased by 2 mV/cell/°C. *(Charge
4. The cable size selected should consider allowable voltage
drop of ≤ 0.5V
*(Battery Connection to Load/Charger 10.12)
12. Verify the battery string voltage matches the rectifier
output voltage. *(Maintenance 11.3)
5. Carefully install batteries into position as determined. The
battery should be oriented so that the negative (-) post of
one battery is adjacent to the positive (+) post of the next
adjacent battery.
13. If a voltage difference is identified due to a voltage drop
in the cables, then the rectifier must be adjusted until the
battery string voltage is within battery specification.
6. Make sure the batteries are all evenly spaced
approximately 10mm (3/8 inch) apart.
7. Check that all contact surfaces are clean, and then install
the bloc or cell connectors and the terminal screws using the
