The plug-socket combination must be accessible at all times, because it serves
as the main disconnecting device. Statement 1019
Follow these steps to install a power supply:
Make sure that the power supply you are installing is not connected to a power
source and that a power cord is not connected to the power supply.
Loosen the two Phillips-head screws from the power supply filler plate (if a filler
plate is present).
Remove the power supply filler plate (if one is present) and set it aside.
Use both hands to grasp a power supply.
Grasp a power supply handle with one hand. Place your other hand underneath to
support the bottom of the power supply.
Slide the power supply almost all the way into the power supply bay. Press with
both thumbs evenly to correctly seat the power supply into the connections inside.
Using a screwdriver, tighten the two captive installation screws on the front panel
of the power supply.
Make sure the power supply power switch is in the off position (O).
Before you connect the power supply to a power source, ensure that all site power
and grounding requirements have been met.
Plug the power cord or cords into the power supply.
Connect the other end of the power cord to a power input source.
In a system with multiple power supplies, connect each power supply to a separate
power source. In the event of a power source failure, if the second source is still
available, it can maintain maximum overcurrent protection for each power
connection.
