Grounding the 300-24
If the power cable used in your installation does not have adequate grounding, or if the
grounding does not meet your installation requirements, you will need to ground the unit
using the ground screw located on the back of the unit. This might occur if you you are
installing the unit on a rack, where solid chassis grounds are mandated by the installation
specialists. The ground wire should be 18 gauge or better and the other end of the wire
should be connected to the rack in the case of a rack mounted installation, or to the
customer’s facility grounding system. Following is an enlarged view of the ground screw
identified in The Back Panel on page 7:
When you ground the unit, you need to insert the ground wire into the hole for the ground
wire and then tighten the ground screw to secure the wire.
With a separate ground installed, the 300-24 may have a better earth ground than the local
AC power outlets; an isolation transformer or laptop PC may be required if ground loop
noise becomes troublesome. Proper electrostatic precautions must be followed.
