4-4 53 COUPE
When these buttons are OFF,
all DC power to the rest of the
boat is disconnected, with one
exception:
Exception:
The port engine
battery bank directly supplies
power to the forward, mid, and
aft automatic bilge pumps. The
house battery bank directly sup -
plies power to the Volvo
®
Active
Corrosion Protection (if Volvo ®
engines are installed). Shutting
OFF the main battery switches
will not disconnect power to
these items.
Power is distributed from the house battery
bank switch on the Master DC Panel to
the DC Distribution Panel located beneath
the starboard salon loveseat ( Figure 4-4 ).
Power to DC components is further distrib -
uted from the DC Distribution Panel.
4.1.4 Automatic Charging Relay
Your Tiara is equipped with an Automatic
Charging Relay (ACR). An ACR automati -
cally parallels (combines) battery banks
during charging, and isolates them when
charging has stopped and battery voltage
has fallen. An ACR is intended to keep a
load from discharging both of the battery
banks it is connected to. The ACR is con -
nected to the port engine battery bank and
the starboard engine battery bank. The ACR, when in
REMOTE MODE,
continu-
ously monitors the voltage in the battery banks and, if needed, automatically
charges the starboard engine battery bank when the port engine is running. The
ACR can be accessed from the bottom of the Master DC Panel on the forward
engine room bulkhead ( Figure 4-5 ).
