AC Power and Grounding Requirements

AC Power and Grounding Requirements
The CTX28 requires a solid earth ground for proper operation. The AC power cord connects to a
standard AC power outlet. The ground for the CTX28 must originate at the building’s main power
distribution panel and have a solid connection to earth ground. (See Figure 1-2.)
Figure 1-2 Ground to AC Power Cord
CAUTION! Lack of proper ground may cause improper operation and, in extreme cases,
system failure.
WARNING! Failure to provide a proper ground may be a safety hazard to service
personnel or lead to confusing trouble symptoms, such as noise on the talk
path including GVMU greetings and messages. In extreme cases, system
failure may result because the system is not properly protected from
lightning or power transients.
