Vertical Installation
Place the cells on the rack (or cabinet) and make sure that the
spacing allows the accommodation of the inter-cell connectors
(around 10mm). Most batteries have cells connected in a simple
series arrangement, so the cells should be arranged to preserve the
sequence: positive (+), negative (-), positive (+), negative (-) throughout
the whole battery.
WARNING
NEVER LIFT CELLS BY THE TERMINAL POSTS. ALWAYS USE
APPROPRIATED DEVICES (SUCH AS LIFTING STRAPS AND
SUITABLE MECHANICAL LIFTING DEVICES) TO PREVENT
INJURY TO PERSONAL OR DAMAGE TO THE CELLS.
For batteries to be installed on multiple tiers, start by placing the cells
on the lower tier on either side of the frame where the stand sections
meet. Any unused stand spaces should be on the upper tier.
For batteries on stepped racks, leave any unused space on the back
(top) step.
Where multiple racks are arranged end-to-end, adjust the position
of the adjacent end cells to accommodate the flexible inter-rack
connectors.
Take particular care to preserve the positive to negative sequence
when using flexible inter-tier, inter-step or inter-rack connectors
between rows of cells. Leave the main positive and negative terminals
of the battery free for connection to the charging source.
Check cell alignment.
Prepare the inter-cell connectors by cleaning the contact surfaces
with a soft clean cloth.
Fit the inter-cell and inter-tier connectors using approved, insulated
bolts and nuts. Ensure all bolts, connectors and cell terminals are free
from dust or debris before connecting.
Use insulated wrenches to tighten the parts firmly together, with
torque setting of 23 Nm (203 in lbs).
Pay special attention to avoid short-circuiting the cells with any of the
battery hardware.
Check tightness and cleanliness.
Horizontal Installation
All Eternity Technology standby cells can be stored vertically and
horizontally.
All Eternity Technology Solar cells up to and including 1200Ah can be
stored both vertically and horizontally. If you require larger Solar cells
to be stored horizontally please contact Eternity Technologies. When
storing horizontally ensure that the internal plates are vertical (to
check this is the correct the positive and negative terminals should be
above or below each other ie not on the same level as per the diagram
below):
5. Charging
a) Commissioning Charge
Batteries lose charge while in transit or during storage. For this
reason, a refresh charge should be given before putting the battery
into service.
Recommended charge settings - at the ambient temperature range
of 20 °C to 25 °C – are as follows:
12 hours at constant voltage of 2.35 Vpc at 20°C (68°F)
{Current limitation 1.5 x I10 Amps}
temperature compensation;
0°C = 2,45 Vpc
10°C = 2,40
20°C = 2,35
30°C = 2,32
35°C = 2,30
b) Float Charge
To maintain the battery in fully charged condition during normal
battery operation or, after a discharge, to recover 90% of nominal
capacity within 20 hours, a recommended float charge has to be
applied.
Recommended float voltage settings are as follows:
Constant voltage 2.25 Vpc at 20°C (68°F) ±1%
{Current limitation 2xI10 Amps}
When all cells have been connected up check the terminal voltage,
this should equal to the sum of all the individual cell voltages. If the
total voltage is different to the calculated figure, some cells may have
been reversed.
Connect the positive terminal of the battery to the positive terminal of
the charger and the battery negative to the charger negative.
Number the cells by using a set of numbering stickers. It is common
practice to number the cells beginning with #1 at the positive end of
the battery and following the sequence of electrical connection of the
cells, through to the negative end of the battery.
Before installing the cells, clean all parts. Remove the short circuit
ABS protectors from the terminal posts and clean them with a soft
clean cloth.
Before replacing old batteries ensure all electrical loads are switched
off.
Battery Room - Points to Consider:
• Ensure the floor is structurally capable of carrying the battery load
• The floor should be resistant to Electrolyte (diluted sulphuric acid)
• There should be no ignitable sources near to the cells
• Ensure there are no unauthorised access points to the battery room
• All rooms should have the correct fire-fighting equipment fitted in
case of emergency.
