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.
Accessories Accessories provided with this product are: 1. Owner's Manual About the Genius-II Power Supply 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 13.65 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.

Installing The Genius-II Power Supply Personnel Installation is to be carried out only by suitably qualified personnel. Ventilation, Orientation, and Thermal 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.
180 mm 138 mm Four 5mm mounting holes 328 mm 316 mm Figure 1: Mounting holes Load, Battery and External DC Input Connections All DC connections should be wired according to Figure 3 on page 11. A block diagram of the basic internal wiring of the Genius-II can be found in Figure 4 on page 14. 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.
Load Connections Up to 10 independently-fused loads may be connected. Loads are attached using the two 10-way terminal blocks. 3.6mm min 8.2mm max Refer to Table 1 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.
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 14.8 volts must be used at all times. Failure to use a voltage regulator may result in power supply damage. Remote Load-isolator 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.

Battery Connection/Disconnection Procedure WARNING: Sparks have the potential to cause an explosion should combustible gases be present. The following procedures are designed to minimise the risk of spark generation while connecting or disconnecting the battery. Battery Connection Procedure The caravan battery should be connected as per the following steps. 1. Remove mains power to the Genius-II Turn off the power switch on the Genius-II 2.
This product is suitable for charging 12 V Sealed Lead-Acid (SLA) batteries including Valve-Regulated Lead-Acid (VRLA) batteries, both Absorbed Glass Mat (AGM) and Gel batteries. Storage If the caravan is to be stored for a long period of time, first fully charge the battery and ensure all loads are disconnected. Recharge the battery at least once every 6 months. Regular recharging will prevent the battery from becoming deeply discharged—a condition which can significantly shorten battery life.

following: The power supply is a three stage battery charger with Boost, Float, and Store charging modes to ensure long battery life. Charging current is limited to a maximum of 15 A. This provides optimum life for the batteries. Details of the charging process can be found in the Battery Charging Management section below. The power supply is able to deliver 35 A maximum to the battery and loads. The 15 A battery charging rate is only possible if the load current is 20 A or less.
