9.6 Connecting Power Cables (Rack Frame PDU)
• Make sure that there is no scratch or flaw on a power cable. It can cause an electric shock or
even a re.
• When inserting the power cable in the connector of PDU, have it inserted completely, and then
x it with a cable clamp, etc. If it is loosened, the connection is damaged, and it causes an
electric shock or re.
NOTE : Make sure that conductors shall be provided with 30 A over current protection in
accordance with Article 240 of the National Electrical Code, ANSI/NFPA 70, and the
Canadian Electrical Code, Part 1, CSA C22.1, Section 14.
1. Open the rear door. (Refer to “How to Open/Close the Door of the RKU Rack Frame”

3. Put out the power cables of PDUs through the Cable passing opening at the bottom of the Rack.
4. Remove the cable holders from the rack frame by removing the hexagon socket head bolts.
5. Fasten the power cables to the rack frame by attaching the cable holders with the Allen bolts.
