Connecting the Mainframe to Earth Ground

VXI Technology, Inc.

CONNECTING THE MAINFRAME TO EARTH GROUND

The CT-400 is configured at the factory for 115 V ac, 60 Hz. The supplied power cord grounding conductor provides adequate grounding for this voltage and frequency level. However, if the CT-400 is to run at anything higher than 63 Hz, the mainframe MUST be connected to earth ground at the mainframe as follows:

1)Connect a 16 AWG (or larger) wire to the ground terminal located on the rear panel (this connection is marked by a symbol). Use a grounding lug with a star washer or a toothed lug, to make this connection. See Figure 2-1.

2)Attach the other end of the wire to a permanent earth ground also using a star washer or a toothed lug.

To avoid electrical shock, the mainframe ground terminal MUST be connected to earth ground for frequencies higher than 63 Hz.

AIR FLOW REQUIREMENTS

The CT-400 must be positioned to provide adequate airflow through the unit. Whether used as a bench-top or rack mount unit, provide at least a one inch clearance, at the back and sides, to allow for adequate airflow. Two air filters are installed in the mainframe at the factory, one for the power supply fan (right side from rear view) and a larger one for the mainframe fans (in the rear at the bottom). These filters may be removed if additional airflow is required, but only if the air is filtered at another source within the rack or if it is installed in a clean environment.
