Introduction
Safety Precautions
Please read the Safety Precautions carefully before installing the power supply.
Be sure to observe all precautions without fail.
After completing installation, conduct a trial operation to check for faults.
WARNING Failure to follow these instructions properly may result in
personal injury or loss of life.
Ensure that there is good ventilation from the battery area.
This appliance is not intended for use by young children or infirm persons
without supervision. Young children should be supervised to ensure that they do
not play with the appliance.
Batteries are electrically alive at all times and must be treated with extreme
caution. They can supply high short circuit currents, even if they appear
damaged.
Take care that dropping or touching of metal objects onto the battery cell does
not cause short circuits.
Remove any personal metal adornment such as a chain, watch or ring, which
could cause short circuits and personal injury.
CAUTION
Failure to observe these instructions properly may result in
property damage or personal injury, which may be serious
depending on the circumstances.
Refer to the installation section before operating. Correct installation is the most
critical factor in ensuring the safe use of the power supply. If every consideration
of these instructions has been satisfied the power supply will be safe to operate.
Ensure that cable connections to batteries have the correct polarity and are
protected against accidental short circuit.
Ensure that the shrouding supplied with the battery is fitted to the terminals.
Before servicing a battery, disconnect the power supply from the mains supply.
Do not charge non-rechargeable batteries. Failure to do so may result in the
battery catching on fire or possible explosion.
Do not allow water or other liquids to enter the installation area.

About the Genius-II Power Supp y
The Genius-II has been designed for use in caravans and similar recreational
vehicles, providing a DC power system with optional battery back up. The units
operate from 240 Vac and provide an isolated 3.65 Vdc output at 35 A for
powering the load and charging the caravan battery. All the necessary protection
and operating features for the load and battery are provided. An optional DC input
is also provided to enable battery charging and powering of the load from an
external + 3.8V DC power source.
The unit is fully enclosed ready for direct wall mounting. All connections are at the
base of unit providing convenient wiring and installation. User access to all load
and battery fusing has been provided at the base of the unit.

Insta ing The Genius-II Power Supp y
Personne
Installation is to be carried out only by suitably qualified personnel.
Venti ation, Orientation, and Therma Considerations
The preferred orientation is with the cooling fins vertical and located such that
there is a minimum of 80 mm free air space above and below them. This allows
for the lowest operating temperature of the internal electronics and hence the
highest reliability of the product.
The final enclosure must also provide adequate ventilation to the outside world (or
larger internal cavity) to prevent excessive heating of the air within the enclosure.
The unit is rated to provide full power in both vertical and horizontal orientations
with enclosure air temperatures up to 50 C.
Note: The enclosure air temperature can easily exceed 50 C if adequate
ventilation is not provided.
The unit has over-temperature protection, meaning it will shut down if its internal
temperature rises above a safe level. The unit will automatically restart once it has
cooled to an acceptable level.
WARNING: Do not install unit in same compartment where flammable
material such as petrol is stored.
Mounting
The Genius-II should be securely mounted to a suitably strong surface, using the
two pre-drilled mounting brackets. Dimensional details are provided in Figure
below.
Mains Cab e
WARNING: If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
This is pre-cabled and fitted with AS/NZ mains plug ready for connection to an
internal 240 V GPO. Ensure that the connection to the mains supply is in
accordance with the national wiring rules, and that the earth connection is
installed.

Load, Battery and Externa DC Input Connections
All DC connections should be wired according to Figure 3 on page .
A block diagram of the basic internal wiring of the Genius-II can be found in
Figure 4 on page 4.
Wire Size
DC cables must be sized to carry the maximum full load current and to not exceed
the system volt drop requirements. The following cable sizes are recommended.
When running wires, if they pass through panels or wall, ensure the wires are
protected form damage by sharp edges. One option is to use cable glands.
Current Minimum Wire Size
0 – 0 A .0 mm² or 8 AWG
0 – 20 A 3.0 mm² or 4 AWG
20 – 30 A 5.5 mm² or 0 AWG

Load Connections
Up to 0 independently-fused loads may be
connected. Loads are attached using the two 0-way
terminal blocks.
Refer to Table for wire size recommendations.
Where the wires connect to the terminal blocks, they
should preferably be fitted with a spade terminal. In
order to fit into the terminal block, spade terminals
need to conform to the dimensions provided in
Figure 2.
Caravan Battery Connection
Connect the caravan battery to the terminals shown in Figure 3 on page .
Refer to Table for wire size recommendations.
The positive connection has an on-board fuse so no additional fusing is required.
External DC Input Connection
CAUTION: Suitable fuse protection must be provided for the “DC In +VE”
input. A fuse rating not exceeding 30 Amps must be used.
The power supply terminal “DC In +VE” provides an alternative option for
powering of the load and charging of the batteries when mains voltages are not
present. This input is to be powered from a suitable + 2 V system. (e.g. your
Car). The voltage of this external DC power source should not exceed 4.8 volts.
This input is diode isolated, so it is strictly an input; the Genius-II will never supply
current to anything connected to this terminal.
This is the preferred input for a car battery connection.
Note: The Genius-II does not provide battery charging management when
operating in this configuration (no mains, DC power provided through the external
input). In this configuration current and voltage control for the battery must be
provided from the external source.
Solar Panel Connection
CAUTION: Solar panels should not be directly connected; a solar panel
voltage regulator must be fitted between solar panels and the battery.
Solar power should (through a series voltage regulator) be connected directly into
the caravan battery circuit. See Figure 3 on page .
The solar power may the wired directly to the caravan battery, or it may be wired

to the caravan battery connections on the Genius-II. Use whichever connection
point is most convenient from a wiring perspective.
Note: A solar panel voltage regulator with maximum output voltage not exceeding
4.8 volts must be used at all times. Failure to use a voltage regulator may result
in power supply damage.
Remote Load-iso ator Switch Connection
The Genius-II allows for remote control of the load connections. A pair of contacts
are provided for connection to the external switch. When this switch is closed, all
loads are disconnected from all power.
Battery charging is not effected by this switch.
The switch current when closed is less than mA, so any convenient switch and
wire size may be used.
