2.7 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.
2.7.1 Grounding Connections
WARNING!!
This unit must be grounded regardless of the power source type (AC/DC) being used.
Consult an appropriate electrical inspection authority or an electrician if you are
uncertain that suitable grounding is available.
Do not connect power before grounding!
Connect the supplied copper wire (CSA 16mm2) GND cable to the GND connector and the
equipment rack or building EARTH.
NOTE: An internationally acceptable color code of the ground connection wire is green/yellow.
To ensure safe operation of the product:
• For a single phase AC power source – ground the unit by connecting the “earth wire” of the
power cord to the ground terminal of the AC supply.
• For a DC power system (such as rectifiers) – do not connect to power systems that switch
open the return lead (the return lead could function as the ground (earth) connection for the
equipment).
