3.2.1 G ro unding
Grounding is a safety measure to have unused electricity return to the ground. It prevents damage to
the Switch, and protects you from electrocution.
Any device that is located outdoors and connected to this product must be properly grounded and
surge protected. To the extent permissible by applicable law, failure to follow these guidelines could
result in damage to your ZyXEL Device which may not be covered by it’s warranty.
1
Remove the M4 ground screw from the Switch’s rear panel.
2
Secure a green/yellow ground cable (16 AWG or smaller) to the Switch's rear panel using the M4 ground
screw.
3
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.
