Grounding the SLX 9140 switch
The rear panel of the SLX 9140 switch includes a dual-screw grounding terminal for NEBS-compliant grounding. The surface area
around this terminal is not painted to provide a good electrical connection. Before connecting power to the device, the grounding terminal
must be connected to ground to meet NEBS compliance.

Connecting the grounding terminal
NOTE
The lug must be sized according to NEC/CEC requirements. A typical installation would require:
•
Lug, copper, suitable wire size, #10 2-hole, 5/8” centers. For #10 ga. wire, some example lugs are:
-
Panduit LCD10-10AF-L
-
Pencom EL1244
-
Hardware Specialties 912302
•
Screw, 10-32, ½", qty 2
•
Washer, #10, external locking, qty 2”
Perform the following steps to connect to the grounding terminal.
1.
Ensure that the rack in which the SLX 9140 switch is mounted is properly grounded and in compliance with local regulations.
2.
Ensure that there is a good electrical connection to the grounding point on the rack (no paint or isolating surface treatment).
3.
Crimp the included grounding lug to a grounding wire of at least 6 American Wire Gauge (AWG). The 6 AWG wire and grounding
lug should be crimped together using a proper tool.
4.
Attach the 6 AWG stranded copper wire to the grounding terminal on the SLX 9140 switch using the screws, flat washers, and
lock washers included in the grounding kit.
5.
Attach the grounding wire to a grounding point.

CAUTION
For the NEBS-compliant installation of an Extreme device with AC or DC systems, use a ground wire of at least 6 AWG. The
ground wire should have an agency-approved crimped connector (provided with the device) attached to one end, with the
other end attached to building ground. The connector must be crimped with the proper tool, allowing it to be connected to
both ground screws on the enclosure. Before crimping the ground wire into the provided ground lug, ensure that the bare
copper wire has been cleaned and antioxidant is applied to the bare wire. In addition, anti-rotation devices or lock washers
must be used with all screw connections for the grounding wire.
