4.9 Symmetry Connection
The ACC controller can supervise 4-block symmetry measurements on 4 battery branches. If
the PCC controller is used, only 2 battery branches can be measured on 4 blocks.
NOTE Symmetry cables are pre-connected to the system.
NOTE Multi Purpose inputs which are not used for symmetry measurement can be
recongured to user dened analog inputs.
1. Insert a suitably sized cable lug into one pole of the inter-block connection plate. Fasten
the lugs and plates to individual battery poles.
2. 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 4-16.
Figure 4-16 2-block Symmetry Measurement (for illustration only)
For 4-block measurement x the 3 wires (red, green and blue) of the symmetry cable to
individual cable lugs. Color coding of the cables must be followed for proper symmetry
measurement, see Figure 4-17.
