3. Place the star washers between the DC grounding cable and the two bolts that you
are using to secure one end of the grounding cable to the two lug nuts.
4. Tighten the two bolts to secure the grounding cable to the two lug nuts.
5. Secure the other end of the grounding cable to the earth ground in the building.
If you are installing the StorEdge S1 storage enclosure in a rack, you can secure the
grounding cable to a proper grounding point on the rack, as long as the rack is
properly grounded to the earth ground in the building.
6. Verify that the DC power source is off through the circuit breakers.
Caution –
Do not proceed with these instructions until you have verified that the
power is off to the DC power source through the circuit breakers.
7. Assemble the DC input power cables, if necessary.
Refer to “Assembling the DC Input Power Cable” on page 20 if you have not already
assembled the DC input cables.
8. Connect the DC input power cables to the DC power source through the circuit
breakers.
Connect the first DC input power cable to DC power source A, and the second DC
input power cable to DC power source B.
9. Connect one DC input power cable to a DC connector at the rear of the StorEdge
S1 storage enclosure.
