INSTALLATION

Step 4. FINAL CONNECTION

Once Steps 1,2 & 3 are completed a final connection should be made from the negative terminal of the
vehicle battery to the Battery Isolator terminal marked BATTERY NEGATIVE. This connection should be made
with cable of 100-200Amp capacity and by keeping as short as possible will offer maximum weight saving of
the complete installation.

Once this final step is complete please check all connections before switching on.

When fitting or removing the Isolator always connect the battery last and disconnect first.

Here is an example of a completed installation:
