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.)

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.
