insulated terminals, use heat shrink tube to cover the non-insulated portion of the
terminal. Choose a terminal ring with the following characteristics:
»
Recommended Wire Strip length: 8mm (0.32in)
»
Width of the terminal block opening: 10.2mm (0.41in)
»
Mouth Size: 6.5mm (0.26in)
3. Remove the front cover by removing the 4 screws at each corner of the charging station.
4. Loosen the plastic cable gland beneath the charger.
5. Loosen strain relief clamp on inside of charger. Use a screwdriver or other tool to break
