Grounding points
You need a protective earthing terminal bracket 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. (You need to provide these screws with
integrated washers as we do not ship them 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 PSM. We recommend the following minimum standards:
•
12 AWG (2.5 mm²), 60° C temperature-rated stranded wire for the ACX5448 router.
•
12 AWG (2.5 mm²), 90° C temperature-rated stranded wire for the ACX5448-D and ACX5448-M routers
To ground the ACX5400 router:
1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.
2. 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. For ACX5448-M routers, remove the dummy screws from the grounding point (see
).
5. Place the grounding cable lug over the grounding points on the side of the chassis (see
for ACX5448 and
ACX5448-D routers and
for the ACX5448-M router).
