Wiring
DC Terminal Connector Locations
Terminal connectors for DC wiring are located on the lower
edge of the circuit board. See
Figure 2-21 .
The common negatives can be reversed or wired with an
appropriately sized single conductor to a more convenient
location such as a DC load center negative bus, if necessary.
The shunt used to measure the current flow in the C-Series
controller is located in the positive conductor of the circuit
allowing greater flexibility in system grounding. The
negative terminals are all common to one another.
Important: Installations should meet all local codes and
standards. Installations of this equipment should only be

WARNING: Shock Hazard
Disconnect battery and PV sources before wiring.
CAUTION: Damage to Batteries
Ensure the voltage selection jumper is set properly before
energizing the system. Incorrect settings may result in damage to
the system as charging regulation will not occur.
Important: Regardless of the configuration, only the positive
conductor from a PV array OR a DC load may be connected to
the terminal marked “PV+/LOAD+”.
