6. 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). If grounding is carried out, ground ONLY the Negative Battery
Terminal.
7. LIGHTNING PROTECTION
In systems subjected to an increased risk of overvoltage damage, we recom-
mend installing additional lightning protection / overvoltage protection to
reduce dropouts. Ask your dealer for technical assistance.

8. MAINTENANCE

The solar charge controller is maintenance-free. All components of the PV
system must be checked at least annually, according to the specifications of
the respective manufacturers. Ensure adequate ventilation of the cooling
element. Check the cable strain relief. Check that all cable connections are
secure. Tighten screws if necessary. Check corrosion on terminals.
9. FAULTS AND REMEDIES
- NO DISPLAY: Check battery polarity and external fuse, OR battery
voltage is too low or battery defective.
- BATTERY IS NOT CHARGED: Check if solar module is connected with cor-
rect polarity or if short circuit at the solar input.
If solar module voltage is lower than battery voltage, or if solar module
is defective, the battery cannot be charged.
- BATTERY DISPLAYS JUMP QUICKLY: Battery voltage changes quickly.
Large pulse currents cause voltage fluctuation. Battery is too small or
defective. Ask your dealer for technical assistance.
The following faults do not destroy the controller if they occur singly. After
correcting the fault, the device will continue to operate correctly:
Solar module short circuits
Short circuits at load output
Reversed battery polarity*
Device over temperature
