2. Connect the solar module
Ensure that the solar module is protected from incident light .
Ensure that the solar module does not exceed the maximum
permissible input current . Connect the solar module connection
cable to the correct polarity of the left pair of terminals on the
solar charge controller (marked with the solar module icon)
3. Finishing steps
Tighten all cables and remove all obstructions to leave a free
space of approx . 15cm around the controller .
Grounding
Be aware that the negative terminals of the controller are
connected together and therefore have the same electrical
potential . If any grounding is required, always do this on the
negative wires .
For common-negative systems, such as a motor home, it is
recommended to use a common-negative controller . But if in a
common-negative system, some common-positive equipment
is used, and the positive electrode is grounded, the controller
may be damaged .
External Temperature Controller
An external temperature sensor may be connected to the solar
charge controller . This sensor measures the temperature at
