To connect the alarm cables to Alarm interface board, follow the steps below:
1. Remove the green plug from each connector.
2. Determine whether to reference normally closed or normally open with reference to
common for each alarm contact.
3.
Strip the wires back approximately 10mm. Stranded wire may be soldered or fitted with
a copper ferrule if desired.
4. Insert wire into the correct positions in the green connector and tighten the screw to
clamp the wire.
5. Insert the green plug back into the Alarm Interface board.
4.10 Symmetry Connection
NOTE
Symmetry cables are pre-connected to the system.
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 fix one wire of the symmetry cable to the
cable lug in the mid-point of the battery string, see Figure 4-11.
Figure 4-11 2-block Symmetry Measurement (for illustration only)
4.
For 4-block measurement fix 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 4-12.
