Installation Instructions
3.1 General Installation Notes
•
Read through the entire installation section first before beginning
installation.
•
Be very careful when working with batteries. Wear eye protection. Have
fresh water
available to wash and clean any contact with battery acid.
•
Uses insulated tools and avoid placing metal objects near the batteries.
•
Explosive battery gasses may be present during charging. Be certain
there is
sufficient ventilation to release the gasses.
•
Avoid direct sunlight and do not install in locations where water can enter
the
controller.
•
Loose power connections and/or corroded wires may result in resistive
connections
that melt wire insulation, burn surrounding materials, or even
cause fire. Ensure tight connections and use cable clamps to secure
cables and prevent them from swaying in mobile applications.
•
Use with Gel, Sealed or Flooded batteries only.
•
Battery connection may be wired to one battery or a bank of batteries. The
following
instructions refer to a single battery, but it is implied that the
battery connection
can be made to either one battery or a group of
batteries.
•
Select the system cables according to 3A/mm
2
current density.
3.2 Mounting
NOTE: When mounting the MPPT40CC, ensure free airflow through
the controller heat sink fins. There should be at least 150mm of clearance
above and below the controller to allow for cooling. If mounted in an
enclosure, ventilation is highly recommended.
WARNING: Risk of explosion! Never install the MPPT40CC in a sealed
enclose with flooded batteries! Do not install in a confined area where
battery gas can accumulate.
