IMPORTANT:
• The cross-sectional area is only for guidance. If there is a considerable distance between the
solar panels and the charge controller, or between the charge controller and the battery,
it is better to choose a larger cross-sectional area to get a lower voltage drop and better
performance.
• The recommended battery cable area applies on the assumption that no extra inverter is
connected to battery.
INSTALLATION
WARNING!
• Risk of explosion. The charge controller must not be installed together with wet cell batteries
in an enclosed and unventilated area or other area where gas can accumulate.
• Electrical safety. When connecting the cables to solar panels the solar panels can generate a
high open circuit voltage. Always switch o the power switch before connecting the cables
and exercise due caution.
• Make sure that there is at least 150 mm of free space over the charge controller to ensure a
sucient air ow.
• Separate ventilation should be arranged for installation in enclosed areas.
INSTALLATION
Choice of installation area with sucient cooling
The charge controller should be installed so that there is a sucient air ow through its cooling ns.
At least 150 mm of free space is required over and under and on each side the charge controller to
ensure sucient inherent convection.
Free installation space, 150 mm on all sides – see diagram.

IMPORTANT:
If the charge controller is going to be installed in a cabinet or other enclosed area there must be
reliable ventilation from the cabinet.
Connection of main components
Connect in the following order: battery - consumer/load - solar panel. Disconnect in the reverse order.
1. Battery
2. Consumer/load
3. Solar panel
