4.2.3 Grounding
Grounding of the controller and connected components in stand-alone systems
is not necessary, not standard practice or may be prohibited by national regula-
tions (e.g.: DIN 57100 Part 410: Prohibition of grounding protective low voltage
circuits). The following grounding possibilities are available if required:
• Positive grounding: One or more of the negative controller terminals can be
grounded.
• Positive grounding: Only one of the positive controller terminals may be
grounded.
CAUTION
X Simultaneous grounding of multiple positive controller terminals will result in
malfunctions or damage to the charge controller.
Consult the technical manual for more information.
