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 on page 11.
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 on page 11.
The solar power may be wired directly to the caravan battery, or to the caravan
