2 If the wayside enclosure isn't attached to a properly installed outside grounding system,
fix this problem before proceeding.
Section 9.1- Grounding System tells how to ground the SmartScanNG² system
properly.
3 Check that all wayside enclosure components are installed properly.
4 Inside the wayside enclosure, check that there are no loose wires or cables.
10.3 Powering-up the SmartScanNG² System
To power up the SmartScanNG² system:
1 If plugged in, unplug the SmartScanNG² detector and the battery charger.
The NRS ELC-12/20-D battery charger doesn't have a power switch. To turn it off, you
need to disconnect it from its power source. Even after AC and DC are disconnected,
a voltage is still present on the DC terminals because of the energy stored in the
capacitor.
The SmartScanNG² detector doesn't have an AC power switch and needs to be
disconnected from its AC power source to stop AC from entering the detector.
However, it does have a DC power switch.
2 If toggled on, toggle off the DC power switch on the right edge of the SmartScanNG²
chassis.
3 Toggle on the AC circuit breaker in the circuit-breaker box.
The next two steps assume your site uses 110-120 VAC. If your site uses
220-250 VAC, skip the next two steps. If your site uses any other AC voltage, skip all
the steps below and call STC for help.
4 Before proceeding, ensure the AC power at all outlets is stable and at least 110 volts at
15 amperes. Confirm that the battery charger is properly grounded to the ground bus
and its vents are not blocked.
There are vents on the top, bottom, and sides of the charger. Blocking any of these
vents could result in damage to the charger or battery.
5 On the front of the unplugged battery charger:
a Check the setting of the input voltage switch on the bottom-right corner.
