Electrical safety precautions for Power Supply replacement
• Make sure that the appliance has a direct physical connection to earth ground during normal
use. When installing or repairing an appliance, always connect the ground circuit first and dis-
connect it last.
• Always unplug any appliance before performing repairs or upgrades.
• Never touch a power supply when the power cord is plugged in. As long as the power cord is
plugged in, line voltages are present in the power supply even if the power switch is turned o.
Replacing an AC Power Supply
Replace an AC power supply with another AC power supply. All power supplies must be of the same
type (AC or DC).
Note: You can replace one power supply without shutting down the appliance, provided the
other power supply is working.
