Ground-Lift Switch
This switch separates the enclosure electrically from the ground potential which helps in preventing “noi-
se-loops”. Noise-loops result from several devices being connected to the ground via mains plugs, when
installed in a rack-system via direct metal contact, and through the screen of connected LF-signal lines.
Grounding Screw
The grounding screw is located next to the ground-lift switch. When the PM2600 is included within a rack-
shelf system, this screw is meant for the connection of an “earth bar”. Whenever several devices are in-
stalled in a rack-system, they should be connected to a common ground, since their lacquered front panels
prevent a perfect galvanic inter-connection between enclosures.
