Cells
ATTENTION!
The electrolyte is a solution of potassium hydroxide (KOH) in distilled water with an addition of
lithium hydroxide (LiOH).
It is recommended to use electrolyte delivered by HOPPECKE.
If this is not possible for some reasons contact HOPPECKE for instructions on mixing.
ATTENTION!
Fill immediately (within 1 hour) electrolyte to an unfilled and uncharged cell after you have
removed the yellow transport plug. Prolonged contact of atmospheric oxygen to the electrodes
can negatively influence the performance.
1. Remove the yellow transport plugs.
2. Fill electrolyte to the each grid|power FNC

cell up to the minimum level + 10 mm.
Note
Topping-up with electrolyte to the maximum level takes place after the commissioning of the
9 Commissioning on page 33
3. Let the cells rest for 1 hour.
4. Insert the yellow transport plugs again.
ATTENTION!
Wait at least 12 hours before you begin with the commissioning works, see

Equipping the Rack or Cabinet
1. Check and clean each cell.
The contact surfaces of the terminals and the connectors must be in a clean and proper
condition.
2. Place the individual cells:
- one after the other
- with correct polarity (for verification use a suitable measuring instrument)
- as shown on the connection drawing, and at right-angles to the horizontal support rails.
Note
You can place the individual cells without any clearance.
A distance of at least 5 mm between the cells is recommend in warmer environments (>
35 °C).
