4.5.6 Symmetry Connection
1. Attach the interblock connection plates between the batteries.
2. Insert a suitably sized cable lug into one pole of the interblock connection plate. Fasten
the lugs and plates to individual battery poles.
3. For 2-block battery symmetry measurement x one wire of the symmetry cable to the
cable lug in the mid-point of the battery string, see Figure 4-11.
4. For 4-block measurement x the 3 wires (red, green and blue) of the symmetry cable to
individual cable lugs. Colour coding of the cables must be respected for proper symmetry
measurement see Figure 4-12.
