Grounding

Grounding
The C-Series controller is designed to work with both
negative ground and ungrounded electrical systems. The
metal chassis of this charge/load controller must be grounded
for either system by connecting it with a copper wire to a
grounding electrode such as a ground rod driven into the
earth.
If a negative ground system is desired, connect the negative
current carrying conductor to the grounding system at one
point in the system. Consult local and national electrical
codes for more information and any additional requirements.
Telecom applications often require a positive ground system.
The C-Series controller switches the PV+/L
OAD+ terminal
with the BATTERY POSITIVE (+) terminal. These terminals
must be kept separate. You can ONLY ground the battery
positive lead in this case, if your local jurisdiction allows it.
