8To replace the supply, reverse the installation procedure. Ensure that the AC power connector is aligned with the cutout in the rear panel, that the supply chassis rests on the two tabs in the instrument chassis, and that the ground wire is routed through the notch at the rear of the power supply chassis.

Cable W2, which is the middle connector in front, connects to the pins toward the top of the supply.

To ensure electrical safety, you must reconnect the ground wire to the chassis.
