Cabling the E-Series Router for Power E-Series Routers

6-11

Task 2: Connect the Grounding Cables

All E-series routers have two grounding studs located in the rear of the chassis, near the power inputs. Each stud provides grounding for a single power unit.

To ground each power unit:

1Locate the grounding studs on the E-series router (see Figure 6-4and Figure 6-5).

2Remove the nuts and locking washers from the grounding studs.

Note: We recommend a minimum of 10-AWG ground wire with a ring style terminal.

3Place the grounding cable lead on one of the grounding studs and tighten the nuts to secure the connection.

4Connect the other end of the ground cable to the appropriate ground termination lead.

5Repeat steps 3–4 for the remaining grounding stud.

Note: When grounding an E-series router, leave a service loop in the grounding cable to ensure that the grounding cable is the last cable to disconnect from the shelf if strain is placed on the electrical cables.

Task 3: Connect the Power Cables

To connect power cables to an E-series router, follow these steps. Refer to

Figure 6-4,Figure 6-5, and Figure 6-6 as needed.

Warning: Be sure the power source is turned off, the E-series router is turned off, and proper grounding wires are attached before continuing with this procedure.
