Desulphation The Desulphation stage is designed to break down sulphation that occurs in batteries that have been left discharged for extended periods of time, this process assists in revitalizing the battery. Sulphation occurs when lead-sulphate hardens and clogs up the battery cells. Soft Start A preliminary charge process that reduces the initial current into the battery.

NEGATIVE EARTHED CONNECTION (Most Vehicles) Connect the RED Output Lead (Battery Clip) from the charger to the Positive (+) Battery Terminal and ensure a good connection is made. Connect the BLACK Output Lead (Battery Clip) from the charger to a clean conductor point on the vehicle's chassis away from any fuel lines or moving parts.
Page 14
CHASSIS EARTHING (Not Essential) The chassis earthing terminal should be connected to an earting point which will be depending on where the battery charger is installed. In a vehicle, connect the chassis ground terminal to the chassis of the vehicle. In a boat, connect to the boat's grounding systems.

MOUNTING INSTRUCTIONS This 8-stage charger is designed for indoor use only and not outdoor conditions (rain and moisture). Ensure that both the charger and battery are in a well- ventilated area during charging. If permanently fixed, the charger should be mounted to a suitable vertical or horizontal panel, with at least 10cm clearance from the end plates to provide adequate ventilation for the cooling fan.
Page 16
PERMANENT WIRING TO BATTERY If required, It is possible to hard wire the DC charging Output Leads to the battery for permanent installations. You will need an Adaptor Lead with Ring Terminals, Fuse, Fuse Holder and a suitable Plug to attach to the current Charger Plug. Alternatively, if you would like to install this yourself please follow the steps below: 1.
