ACX5448 Universal Metro Router Quick Start Guide
Step 3: Connect the Grounding Cable
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the router must be adequately
grounded before power is connected.
A protective earthing terminal bracket is required for connecting the chassis to earth ground. This two-holed bracket attaches
on the side of the chassis through the mounting rail and provides a protective earthing terminal for the router. The grounding
points are in the form of studs sized for #10–32 pan head screws. The #10–32 pan head screws with integrated washers are not
provided in the accessory kit. The grounding points are spaced at 0.63-in. (16-mm) centers.
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis grounding points by
using two #10–32 pan head screws. You must provide the grounding cables.
NOTE:
The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided). The grounding lug
accommodates 12 AWG (2.5 mm²) stranded wire. The grounding cable that you provide for the chassis must be the
same size or heavier than the input wire of each power supply. Minimum recommendations are 12 AWG (2.5 mm²)
stranded wire, 60° C wire, or as permitted by local code.
To ground the ACX5448 router:
Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the other end of the strap to an
2.
approved site ESD grounding point. See the instructions for your site.
Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections are made.
3.
Connect the grounding cable to a proper earth ground.
4.
Detach the ESD grounding strap from the site ESD grounding point.
5.
Connect the grounding strap to one of the ESD points on the chassis.
