AC Power and Grounding Requirements
The CTX100 requires a solid earth ground for proper operation. The five ft. AC power cord
contains a conductor for the "third-wire ground" provided by the commercial power outlet. The
third-wire ground should be the only ground necessary for each CTX100 cabinet; this ground must
originate at the building's main power distribution panel and have a solid connection to earth
ground. (See

Distribution Box)
Figure 2-2
CAUTION!
An inter-cabinet ground wire connecting the Base and Expansion cabinets is not necessary.

Power Considerations

The power supply in each Strata CTX100 Base and Expansion Cabinet furnishes power to all of
the PCBs and stations and some of the interface peripherals. The primary AC power for each
cabinet is 120VAC (see
