5. Verify that the Power LED is off.
6. Disconnect the input power connector(s) on the rear of the unit, or open all circuit
breakers associated with the unit.

Regardless of the position of the ON/STBY switch, where an AC power cord
remains connected to the system, hazardous voltages are always present within the
