3 Installation Instructions

3.1 Mounting

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 singular battery, but it is implied that the battery connection can
be made to either one battery or a group of batteries in a battery bank.
 Select the system cables according to 3A/mm
NOTE: When mounting the controller, ensure free air through the
controller heat sink fins. There should be at least 6 inches (150 mm)
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 controller in a
sealed enclose with flooded batteries! Do not install in a confined
area where battery gassed can accumulate.
