First connect the L+ load cable to the correct pole of the right pair of ter-
minals on the solar charge controller (with the lamp symbol), then connect
the L– cable.
Replace the load fuse or switch on the load.
4th step: final work
Fasten all cables with strain relief in the direct vicinity of the solar charge
controller (clearance of approx. 10 cm).
4.2.3 Grounding
The components in stand-alone systems do not have to be grounded – this is
not standard practice or may be prohibited by national regulations (e.g.: DIN
57100 Part 410: Prohibition of grounding protective low voltage circuits). Con-
sult the technical manual for more information.
4.2.4 Lightning protection
In systems subjected to an increased risk of overvoltage damage, we recom-
mend installing additional lightning protection / overvoltage protection to
reduce dropouts. Consult the technical manual for more detailed information.
5. Operation
The solar charge controller immediately begins operation once the battery is
connected or the external fuse is inserted.
The display of the solar charge controller shows the current operating mode.
User intervention or user settings are not required.
Protection functions
The following integrated protection functions of the solar charge controller
ensure that the battery is handled as gently as possible.
The following protection functions are part of the basic function of the controller:
overcharge protection
deep discharge protection
battery undervoltage protection
solar module reverse current protection
The following installation faults do not destroy the controller. After cor-
recting the fault, the device will continue to operate correctly:
protection from solar module short circuits / incorrect solar module polar

ity
protection from short circuits at the load output or excessive load
