4.3 Battery Surge Protection and Power Wiring
Battery surge protection for the SSCC is shown in Figure 4-3. The Primary surge protection for
SSCC modules is provided on the SSCC battery (see inside dotted line). The Primary surge
protection for I/O interconnect is provided on lighting surge panels (see paragraph 4.3.1).
Provide power wiring to A80405 SSCC IIIi modules:
•
via B and N contacts of the respective crossing controller connectors on the
GCP5000 (GCE) front panel.
•
using poly-jacketed #10 AWG wire (recommended) for DC power and return
between battery surge protection and the GCP5000 (GCE) crossing controller
connectors.
Provide power wiring to the lighting surge panels:
•
using poly-jacketed #6 AWG wire (recommended) for DC power and return between
the –1 lighting surge panel (A91170-1 or A91181-1) and the crossing gate battery
posts.
•
using poly-jacketed #10 AWG wire (recommended) for DC power and return
between the –1 lighting surge panel (A91170-1 or A91181-1) and the –2 lighting
surge panel (A91170-2 or A91181-2).
PROPER BATTERY SURGE PROTECTION REQUIRES THAT THE
BATTERY CHARGER OUTPUT BE WIRED DIRECTLY TO THE
OPERATING BATTERY POSTS WHILE A SEPARATE PAIR OF WIRES
RUN FROM THE BATTERY POSTS TO THE SSCC SURGE
PROTECTION (ACROSS THE EQUALIZER) AS SHOWN IN Figure
