Ground the Chassis


Warning


Statement 1024—Ground Conductor

This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.



Warning


Statement 1046—Installing or Replacing the Unit

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

If your unit has modules, secure them with the provided screws.



Caution


Grounding the chassis is required, even if the rack is already grounded. A grounding pad with two threaded holes is provided on the chassis for attaching either a grounding lug or grounding cover plate. The ground lug must be NRTL-listed. In addition, a copper conductor (wires) must be used and the copper conductor must comply with NEC code for ampacity.

Caution


When terminating the frame ground, do not use soldering lug connectors, screwless (push-in) connectors, quick connect connectors, or other friction-fit connectors.

Procedure


Step 1

Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the #6 AWG grounding cable.

Step 2

Insert the stripped end of the grounding cable into the open end of the grounding lug.

Step 3

Use the crimping tool to secure the grounding cable in the grounding lug.

In NCS-57D2-18DD-SYS routers, vertical crimping is required to secure the grounding cable.

Step 4

Attach the ground cable:

  1. Remove the adhesive label from the grounding pad on the chassis.

  2. Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the provided screws with washers through the holes in the grounding lug and into the grounding pad.

Connect AC Power to the Chassis


Caution


The chassis relies on the protective devices in the building installation to protect against short circuit, overcurrent, and ground faults. Ensure that the protective devices comply with local and national electrical codes.

Caution


In low-line applications (90-140V AC), redundancy is not guaranteed. Therefore, we recommend to use both AC power supplies.

Note


To obtain full output power of the PSU, the nominal voltage rating value varies, depending on the standards in various countries.



Note


A dual pole breaker is needed for the installation. The rating of the dual pole breaker for 110 V is 20 A and for 220 V is 16 A. The minimum cable size is 14 AWG for 110 V and 16 AWG for 220 V.

Procedure


Step 1

Verify that the AC cable is installed in the correct AC source panel.

Step 2

Attach the AC power cable to the cable connector in the AC power module.

Step 3

Place the cable through the opening in the cable clamp.

Step 4

Slide the cable clamp toward the plug.
