CAUTION: Before packet transport router installation begins, a licensed
electrician must attach a cable lug to the power cables that you supply. A
cable with an incorrectly attached lug can damage the packet transport
router.
CAUTION: You must ensure that power connections maintain the proper
polarity. The power source cables might be labeled
their polarity. There is no standard color coding for DC power cables. The
color coding used by the external DC power source at your site determines
the color coding for the leads on the power cables that attach to the terminal
studs on each PDU.
The accessory box shipped with the packet transport router includes 0-AWG and 4-AWG
cable lugs . The cable lugs are dual hole, and sized to fit 1/4-20 UNC terminal studs at

You attach these cable lugs to the DC terminal studs of each input power tray of the
60-A and 120-A PDUs and to the terminal studs (16 for eight PSMs) in the front of the
High Capacity DC PDU. The 0-AWG cable lug is also used for grounding the packet
