Precautions and Electrostatic Discharge Prevention:
Service Instructions: 64-1000
.
Warning:
Hazardous voltages are present within
the inverter when power is applied. Do not remove
the inverter’s top cover without
fi
rst turning off
and disconnecting all AC and DC power to the
inverter. Always replace the top cover before
reconnecting power.
Warning:
The capacitors inside the inverter
store electric energy even after all AC and DC
power is removed. After disconnecting all AC
and DC power to the inverter, wait 5 minutes for
the energy in the capacitors to dissipate before
working on the unit.
Caution:
Observe all ESD safety precautions
when working with the control and FET boards,
and within the inverter. Failure to follow ESD
safety precautions could result in damage to
internal components and the inverter.
2.2 Included
Materials
Before dismantling the inverter, inspect the new control
board to ensure there is no obvious physical damage. Look
at the Model ID label on the new control board (see Figure
