Task 2: Connect the Grounding Cables

Task 3: Connect the Power 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:
1
Locate the grounding studs on the E-series router (see
Figure 6-5).
2
Remove the nuts and locking washers from the grounding studs.
Note: We recommend a minimum of 10-AWG ground wire with a ring style
terminal.
3
Place the grounding cable lead on one of the grounding studs and
tighten the nuts to secure the connection.
4
Connect the other end of the ground cable to the appropriate
ground termination lead.
5
Repeat 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.
To connect power cables to an E-series router, follow these steps. Refer to
Figure 6-4, Figure 6-5, and
ERX-7xx models, ERX-14xx models,
ERX-310 router (DC model)
Caution: Before you begin this procedure, ensure that all power switches are in
the OFF position.
1
Be sure you have completed Task 1 and Task 2 in the previous
sections.
2
If applicable, loosen the screws from the clear power input module
cover and remove it.
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.
