WARNING
A fuse must be installed in the positive
connection of the battery. This fuse
MUST be as close as possible to the
battery. This fuse protects against
short circuits and reverse battery
conditions. A fuse rating no greater
than 40 Amps must be used.
Caravan Battery Connection
Connect the caravan battery to the terminals shown in Figure 3: DC Wiring Diagram
for
BatteryPlus35SR
and
BatteryPlus35HA
. The battery negative return must be
connected to the
BatteryPlus35
“BATT-” only.
The battery negative must not be directly connected to the chassis.
In order to avoid incorrect current readings and battery capacity errors, DO NOT
make any connections directly to the battery.
Up to 14 independently-fused loads, may be connected. Loads are
attached using female spade Quick Connects (QC).
See Figure 2: Quick Connect Dimensions.
Refer to Table 1: Wire Size Recommendations for wire size
recommendations.
All load negative returns must be connected directly to the
BatteryPlus35 negative terminals
only.
Caravan Battery Connection
WARNING
A fuse must be installed in the positive connection
of the battery. This fuse MUST be as close as possible to the
battery. This fuse protects against short circuits and reverse battery
conditions. A fuse rating no greater than 40 Amps must be used.
Connect the caravan battery to the terminals shown in Figure 3: DC Wiring Diagram for
BatteryPlus35SR and BatteryPlus35HA. The battery negative return must be connected to the
BatteryPlus35 “BATT-”
, only.
The battery negative must not be directly connected to the chassis.
In order to avoid incorrect current readings and battery capacity errors, DO NOT make any
connections directly to the battery.
AX (Auxiliary) DC Input Connection
CAUTION
Suitable fuse protection MUST be provided for the “AX” input. A fuse rating not
exceeding 30 Amps must be used.
The power supply terminal “AX” provides an alternative option for powering the loads and charging of
the batteries when mains voltages are not present. This input is to be powered from a su12 V
system (e.g. a vehicle). The voltage of this external DC power source should not exceed 14.8 V.
This input is isolated using an internal relay, so it is strictly an input; BatteryPlus35 will never supply
current to anything connected to this terminal. The AX voltage must be 0.5V greater than the battery
voltage for charging to occur. If the current supplied by the AX input is less than 2A then the charging
will stop.
This is the only input for a car connection. Refer to AX Charging on page 26.
Note:
BatteryPlus35 does not provide battery charge management when operating in this
configuration. In this configuration current and voltage control for the battery must be provided from
the external source.
Note:
The BP35 and loads can be powered directly from the Auxiliary input and does not require a
battery.
Solar Connection
This connection is for solar panel connection for the BatteryPlus35SRHA and for a solar
regulator/controller connection for the BatteryPlus35PM.
BatteryPlus35SR and BatteryPlus35HA versions
BatteryPlus35SR/HA have a solar input to which standard 12V solar panels are to be connected to this
input. This input is internally connected to a Maximum Power Point Tracking (MPPT) charger which is
able to charge a 12V battery system and provide power to the loads. This MPPT charger is a smart,
multi-stage, 450W regulator which is capable of delivering up to 30A. The charging stages are
described in Figure 8: Charging Algorithm.
