3.4 GX Connections
IMPORTANT – CABLE DRIP LOOPS!
It is highly recommended that every horizontal cable entry to the equipment forms a 'U' before its entry to the equipment.
Water on the cable will drip down at the bottom of the loop and will not accumulate at the equipment connectors.
The connections are performed from the underside of the GX unit after it has been mounted.

WARNING!
This unit must always be grounded. Consult an appropriate electrical inspection authority or an electrician if you are uncertain

Note: An internationally acceptable color code of the ground connection wire is green/yellow.
To ground the GX unit:
1. Connect the supplied copper wire (AWG #6) GND cable to the GND connector and the equipment rack or building earth.
2. Ground the GX unit by connecting the provided “earth wire” of the power cord to the ground terminal of the AC supply.
