AC Power and Grounding Requirements
The CIX40 requires an earth ground connection for proper operation. The two-wire AC power cord
connects to a standard AC power outlet, and does not provide a ground connection. The ground
for the CIX40 must originate at the building’s main power distribution panel and have a solid
connection to earth ground. Use a an insulated copper wire to connect the TB3 terminal on the
GMAU2 to earth ground. This wire should be 10 AWG or larger. The total resistance from TB3 to
the ground point must not exceed one ohm. Connect the ground wire to the common ground point
or ground rod, usually located at the utility entrance of the building. (See Figure 1-7.) Check local
codes.
Figure 1-7 Ground and AC Power Cord
Important! Do not wrap the power cord around the AC adaptor. Excess cord should be
gathered and secured with the supplied strap as shown in Figure 1-7. Wrapping the
cord around the adaptor, or bundling the output cord with the AC cord can cause
noise on voice mail messages or other noise.
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 GVPH1 greetings and messages. In extreme cases, system
failure may result because the system is not properly protected from
lightning or power transients.
