# Required Tools, Wires, and Cables

Cabling your system takes only a few minutes. You need the following items and those listed in Table 6 for proper installation:

- 1/8-inch flathead screwdriver
- 3/8-inch wrench or 3/8-inch nut-driver
- No. 2 Phillips screwdriver
- Ground wires—We recommend a minimum of 6-AWG ground wire.
- Two #10 kep nuts (supplied) to connect the ground (earth) wire to the ground terminal.
- PDU wiring—We recommend a minimum of 4-AWG wire for the router with a dual stud terminal lug with 5/8-inch spacing.

Consider the distance from the connection point and the configuration of the system when determining the size of wire used.

See System Specifications for more information on router specifications.
