Removing and Replacing the Power Supply
Step 1
Verify that power is off to the DC circuit that is connected to the power supply you are installing. Place
appropriate safety flag and lockout devices at power switch handle to avoid any circuit inputs from
becoming energized.
Caution
Use both hands to install and remove power supplies. Each PWR-6000-DC weighs 35 pounds (16 kg).
Step 2
Grasp the power supply handle with one hand, and place your other hand underneath the power supply.
Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the
bay (
