Other Electrical Considerations

Precautions must be taken to prevent electrostatic discharge when servicing the Controller and related components. A potential difference less than that required to create a small spark between a finger and a doorknob can cause severe damage to solid state components.

Always disconnect the negative battery terminal (-) first when removing a battery. Connect the positive terminal (+) first when installing a battery. This is important because the frame is grounded to the negative battery terminal. If the negative terminal is still connected, a complete circuit exists from the positive terminal of the battery to the frame. Metal objects contacting the positive side and the frame simultaneously will cause sparks or arcing. If there are sufficient hydrogen gases emitted from the battery, an explosion might occur, causing equipment damage, serious injury, even death.

Always cover battery terminals to prevent them from making contact with metal components.

Always switch off the high voltage energy supply and disconnect the electric cable before working on the unit.
