4.5.6 Crossing Controller DC Power Connections
The A80405 modules receive power via the Lighting Surge panel and the
CROSSING
CONTROLLER
connectors as shown in Figure 4-11:
The surge panel provides primary battery surge protection.
Secondary surge protection provided by each A80405 module
Make power connections to each A80405 module via the
B
and
N
contacts of the respective
CROSSING CONTROLLER
connectors:
Poly-jacketed 10AWG wire is recommended for DC power and return between the lighting surge
panel and the GCP5000 (GCE).
Poly-jacketed 6 AWG wire is recommended for DC power and return between the lighting surge
panel and the crossing battery.
