For detailed information regarding Alarm connection
see Appendix A, Installation Drawing.
4.13 Symmetry Connection
The ACX controller can supervise 4-block symmetry measurements on 4 battery branches.
NOTE
Symmetry cables are pre-connected to the system.
NOTE
Multi Purpose inputs which are not used for symmetry measurement can be
reconfigured to user defined 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 fix one wire of the symmetry cable to the
cable lug in the mid-point of the battery string, see Figure 4-13.
