Pre-installation
Upon delivery the Solar Charger Unit is installed as follows:
-
Gas control active (see functions)
The above functions can be turned off at any time.
Gas control de-activate
1.
Unscrew the 4 screws (see diagram) on the Solar Charger Unit and carefully remove the sassing/lid.
2.
Disconnect the jumper J6. The gas control is now de-activated.
Installation – Warning: Take care that the Terminals/Poles correspond!!!
The Solar Charger Unit should be placed in close proximity to the battery and be sufficiently protected against the weather. Take care to place
the battery in a well ventilated place. To enable the unit to function properly, the electrical connections should face downwards. To guarantee
that the unit functions properly it must be connected to the solar generator, the lead-battery and the load.
Each part of the system-solar generator, lead battery, load and Solar Charger Unit should have the corresponding power supply. Please check
each component before installation, when in doubt contact a specialist! Take careful attention on the following installation instructions:
1.
Connect the battery to the corresponding terminals on the Solar Charger Unit. To prevent the wiring from overheating and power supply
reduction the use of cable/wire 2.5 mm² flexible is recommended. Use always fuse to connect to the battery +terminal/pole. Both
components must be installed close together in the same room.
2.
Connect the solar panel to the corresponding terminals on the Solar Charger Unit.
3.
Connect the load to the Solar Charger Unit. The connection-terminals pictured on the Solar Charger Unit or see diagram.
Temperature sensor
Battery – complete loading The LEDs indicate the level of recharging. The present charging level of the solar panel and possible
Protection against over discharge (LED red)
By over discharge the load is automatically switched off and the LED is red. When the rechargeable battery is recharged, the LED does not
illuminate. The rechargeable battery is ready to be used.
The Solar System fails to Function – possible reasons
Battery terminals/poles are wrongly connected: Avoid at all costs!!!
Load terminal/poles are wrongly connected: The apparatus can be seriously damaged before the fuse blows. Batteries contain considerable
amounts of electrical energy. A short-circuit can result in a large build-up of heat leading to FIRE!!
Two LEDs indicate the operating conditions under different circumstances and possible mal-functions in the Solar Charger Unit.
