3.2.3 Grounding (NSW200-28P)

Grounding is a safety measure to have unused electricity return to the ground. It prevents damage to
the NSW and protects you from electrocution.
Remove the M4 ground screw from the NSW's rear panel.
1
Secure a green/yellow ground cable (16AWG or smaller) to the NSW's rear panel using the M4 ground
2
screw.
Attach the other end of the cable to the ground, either to the same ground electrode as the rack you

installed the device on or to the main grounding electrode of the building.
Follow your country's regulations and safety instructions to electrically ground the device properly.
If you are uncertain that suitable grounding is available, contact the appropriate electrical inspection
authority or an electrician.
Note: Qualified service personnel must confirm that the building's protective earthing
terminal is a valid terminal.
Warning! Connect the ground cable before you connect any other
cable or wiring.
