block covers.
Step 15 After you confirm that all installation steps are completed correctly, remove any safety flags, lockout
devices, or adhesive tape from the source DC circuit breakers, and energize the input circuits to the
power supplies.
Step 16 Turn the power switch to the On (|) position on the power supply. Turning on the power switch also
engages a pawl that locks the power supply in the chassis.
Verify the power supply operation by ensuring that the power supply front panel LEDs are in the

You should allow a minimum of 2.5 to 3 inches (63.5 mm to 76.2 mm) of space between the side of the
Note
power supply and any obstructions (such as the side of an enclosed equipment rack). This space is needed
to install and secure the DC-input power cables correctly. Incorrectly routing the DC-input power cables
can cause airflow blockage into the power supply and inadequate strain relief in the cables. The exact
amount of space required depends upon the gauge and flexibility of the DC-input power cables that you
are using.
Follow these steps to install a 4000 W DC-input power supply that is going to be wired for 2700 W
operation in the right power bay (POWER 2):
Ensure that the system (earth) ground connection has been made. For ground connection installation

Verify that power is off to the DC circuit that is connected to the power supply that you are installing.
Step 2
As an added precaution, place the appropriate safety flag and lockout devices at the source power circuit
breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power
restoration while you are working on the circuit.
Prepare the source DC-input power cables by attaching the appropriately sized lugs.
