Connecting Earth Ground to an ACX5000 Router
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the ACX5000 router to earth ground before you
connect it to power.
For installations that require a separate grounding conductor to the chassis, you must
attach a protective earthing terminal bracket on the ACX5000 router left front mounting
bracket to connect to the earth ground (see Figure 35 on page 113).
Before you connectearth ground to theprotective earthing terminal of a ACX5000router,
ensure that a licensed electrician has attached an appropriate grounding lug to the
grounding cable.
CAUTION: Using a grounding cable with an incorrectly attached lug can
damage the router.
NOTE: Mount yourrouter inthe rack or cabinet beforeattaching the grounding
lug to the router. See “Mounting an ACX5000 Router in a Rack or Cabinet”
on page 104.
Ensure that you have the following parts and tools available:
•
Protective earthing terminal bracket—This bracket attaches to the router chassis
through the left front mounting bracket, providing a protective earthing terminal for
the router.
•
Grounding cable for your router—The grounding cable must be 14 AWG (2 mm²),
minimum 90° C wire, or as permitted by the local code.
•
Grounding lug for your grounding cable—The grounding lug required is a Panduit
LCD10-10A-L or equivalent.
•
Two M4 hex nuts with integrated washers—Two nuts and washers are used to secure
the grounding lug to the grounding lug bracket protective earthing terminal. Four nuts
are provided in the accessory kit.
•
7-mm wrench or socket with driver to attach the two nuts.
An AC-powered ACX5000 router chassis gains additional grounding when you plug the
power supply in the router into a grounded AC power outlet by using an AC power cord
appropriate for your geographical location. See “AC Power Cord Specifications for an
ACX5000 Router” on page 54.
