4.9.3 Battery charging by mains power
In mains powered terminals the 12 V battery is charged by the battery loader that
outputs 12 V (13.8 V) to the battery via a separate 6.3 A fuse.
The charger has three indicators:
GREEN ON when 230 V (115 V UK) Mains power is available.
YELLOW ON when charging is in progress.
RED Initially ON when a deeply discharged battery is being charged.
The charger also has a 12 V distribution panel with three output connectors and
two 230 V (115 V UK) outputs for optional heating fans.
A diode in the battery charger protects the circuitry if the battery is connected
with wrong polarity. In such a case one or both of the main fuses F1 and F2 on
the CPU board may blow.
The cable from the mains power grid is connected to a termination block in the
Pedestal. The termination block contains a residual-current device, optionally
combined with a fuse.
