■read the section “Using an AT-PWR03 Power Supply (PSU)” on page 9

Warning Disconnect the power cord before removing the PSU.

1.Disconnect the power to the PSU.

For AC models, turn off the main power supply to the PSU and disconnect the power cord.

For DC models, push the run/standby button on the back of the PSU, so that the PSU is in the standby position. When the button is not depressed, it is in standby. Disconnect the supply cable from the PSU and the DC power supply. To remove the DC plug from the back of the PSU, squeeze the two locking tabs while pulling out.
