4. When connecting the PDU to the wall outlet, be sure to secure the main power cable with the clamp,
as shown in the figure below.
5. Connect power cables from devices to the PDU, then connect PDU to the wall outlet or UPS.
6. Turn on power to devices.
Installing PDUs Horizontally
The PDUs can be installed horizontally, with the each end of the PDU secured to each of the rear rack
columns. However, you must use the EIA holes (the row of holes on the inner edge of the rack column)
for this configuration.
1. Determine where you will place the PDU on the rear rack columns (usually across the top or across
the bottom). Consider if you need access to any of the rack equipment, then locate the PDU so the
power cables do not hinder access to the equipment.
Note: If the PDU will be used to connect to the wall outlet, be sure to place the PDU toward the
bottom of the rack. This allows the cable to extend easily out the bottom of the rack, under the
rear door (if a rear door is installed).
2. Attach the PDU to the EIA holes in the rack column with the Torx screws and hex nuts.
