Precautions when handling the new inverter 70
The control circuitry has an uninsulated construction 70
A high voltage equivalent to the supply voltage is also energized to ground through the sensors pmv and other low voltage circuits the sensor leads and other wires are covered with insulated tubes for protection nevertheless care must be taken to ensure that these wires are not pinched 71
At times such as when the circuit board is to be replaced place the circuit board assembly in a vertical position 71
