INSTALLING THE GENIUS-II POWER SUPPLY

PERSONNEL

Installation is to be carried out only by suitable 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.

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 1.

Figure 1: Mounting holes

MAINS CABLE

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 EXTERNAL DC INPUT CONNECTIONS

All DC connections should be wired according to Figure 3.
A block diagram of the basic internal wiring of the Genius-II can be found in Figure 5.

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 from damage by sharp edges. One option is to use cable glands.

CURRENT

| MINIMUM WIRE SIZE
---|---
0 — 10A|

1.0mm² or 18 AWG

10 — 20 A

| 3.0mm² or 14 AWG
20 — 30 A|

5.5mm² or 10 AWG

Load Connections

Up to 10 independently-fused loads may be connected. Loads are attached using the two 10-way terminal blocks.

Refer to Table 2 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.
Refer to Table 2 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 +12 V system (e.g. your Car). The voltage of this external DC power source should not exceed 14.8 V.

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. The solar power may be wired directly to the caravan battery, or 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 V must be used at all times. In some situations the led can blink randomly, this is because the solar charger voltage is greater than the charger voltage. This occurs only when the mains and the solar charger are both present.

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. 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 1 mA, so any convenient switch and wire size may be used.

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. Disconnect all loads Turn off all 12V equipment connected to the Genius-II
3. Connect the positive battery terminal
4. Connect the negative battery terminal

If the battery negative is connected to chassis, ensure a connection exists from chassis to the “Bat—VE” terminal of the Genius-II.

Battery Disconnection Procedure

The caravan battery should be disconnected as per the following steps.

1. Disconnect all loads Turn off all 12V equipment connected to the Genius-II or disconnect the loads using the remove load-disconnect switch
2. Remove mains power to the Genius-II Turn off the power switch on the Genius-II
3. Disonnect the negative battery
4. Disconnect the positive battery terminal

BATTERIES

Note: This battery charger is rated to charge lead acid batteries of up to 300 Ah capacity. Charging current is limited to 15 A or 30 A depending on the type of the model. Refer to About the Genius-II Power Supply.

When using batteries with this product always consult with the battery manufacturer for a detailed description of the installation, use and maintenance of the battery.

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.

CHARGE CURRENT

| BATTERY CAPACITY|

CHARGING TIMES

---|---|---
15 A| 100 Ah| 8 hours
200 Ah| 16 hours
30 A| 100 Ah| 4 hours
200 Ah| 8 hours
300 Ah| 12 hours

Table 3: These charge times are based on continuous charging with an initial battery voltage greater than 10.5V

PARALLELING BATTERIES

When paralleling batteries together, all the batteries MUST be:

• of the same type, e.g. deep cycle battery
• of the same capacity, e.g. 100 Ah
• of the same manufacturer
• fully charged before connecting them together

WARNING

Do not install battery in the same compartment where flammable material such as petrol is stored.

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.

DEEPLY DISCHARGED BATTERIES

This battery charger is not designed to charge deeply discharged batteries. Its effectiveness in charging such a battery is a function of the depth of discharge and the battery size. Bigger (higher capacity) batteries will be more troublesome in this respect.

In normal use a battery connected to the Genius-II should never become deeply discharged, so recharging it should never be a problem.

If a battery has become deeply discharged and the Genius-II will not charge it, remove the battery (see Battery Connection/Disconnection Procedure on
page 10) and charge it with a stand-alone charger. Once the battery voltage has recovered to normal levels and the charge current is less than 15 A, it may be reinstalled.

FUNCTIONAL DESCRIPTION

FUNCTIONAL DIAGRAM

AC/DC POWER SUPPLY

This provides an isolated 13.65 V DC output for powering of the load and charging of the battery. Battery current is sensed and monitored by the power supply to limit the charging current to 15 A or 30 A maximum depending on the model. Refer to About the Genius-II Power Supply.

FAULT PROTECTION

The power supply provides automatic protection for overload including short circuit, over-voltage, over-temperature and reverse connected battery. In overload, short circuit, and over voltage condition the power supply will shut down. It will then automatically attempt to restart every 5 seconds until such case that the fault is removed.

FUSING

Each load circuit and the caravan battery connection have been fused to provide fault protection and discrimination. Refer to the servicing section for fuse ratings.

BATTERY CHARGING FEATURES

The power supply (Genius-II) provides full battery management as per the 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 or 30 A maximum depending on the model. 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 on all models. For GENIUS-II, GENIUS-IIA and GENIUS-IIN, the 15 A battery charging rate is only possible if the load current is 20A or less. If the load current exceeds 20 A, the maximum battery charging current will be reduced accordingly. The same logic goes for GENIUS-IIH, GENIUS-IIHA and GENIUS-IIHN models, but have maximum battery charge current of 30 A.

Note that for the Genius-II to operate in the manner described above, all loads must be connected to load terminals, not directly to the caravan battery.

Low Voltage Disconnection of the batteries is provided to prevent deep discharge of the battery. Automatic reconnection occurs when battery voltage recovers. Battery Current Drain is less than 3 mA.

BATTERY CHARGING MANAGEMENT

To maintain the battery in a good state of health, an intelligently controlled charging algorithm is used. The purpose is to ensure that the correct voltages are applied to the battery terminals at the appropriate times throughout its usage cycle. The basics of the charging algorithm are detailed in Figure 6.

Float Mode

During Float mode the battery is charged at 15 A until the float voltage is reached. Then it changes to constant voltage charging.

If the float voltage has been reached and the mains is interrupted for more than an hour, then upon recovery of the mains the unit switches to Boost mode for 15 minutes and then returns back to Float mode.

Store Mode Periodic Boost Mode

Store mode is activated when the battery has been in Float mode for 24 hours (long enough for the battery to be fully charged).

During Store mode the unit switches to Boost mode for 15 minutes every 24 hours (called Periodic Boost mode).

During Periodic Boost mode if the mains is lost for more than 2 minutes, then upon recovery of the mains the unit switches to Float mode.

Battery Charging Store Mode

During Float charging (typically at 13.65 V) there is continuous charging current into the battery, sufficient in a long term charging situation to cause corrosion the battery positive plate. To prevent this corrosion the charger utilises what is called a Storage mode, where the charging voltage is reduced to 13.25 V. In this mode the charging current is very small, usually less than the battery’s selfdischarge current.

If left continuously in Store mode, the battery would slowly discharge, so to prevent this the charger switches to Boost mode for 15 minutes once a day. This is sufficient to keep the battery fully charged.

The net result is a battery which can be left on charge indefinitely without the usual battery degradation problems from continuous charging.

LED INDICATOR

A multi-colour LED indicator is provided to indicate the following operating Conditions.
