G430 and EM200 Grounding Requirements
Note:
Note: Grounding requirements differ widely from country to country. In addition to the grounding
instructions presented in this section, you must follow the local electrical installation codes for
your location.
You must use two safety grounds to ensure safe operation of each G430 Media Gateway and EM200:
Both safety grounds must be connected to an approved ground (see Chapter 2 of Installing and Upgrading
the Avaya G430 Media Gateway, 03-603233, for the definition of an approved ground). If a power cord
accompanies the G430 or EM200, use that cord whenever possible.

WARNING:
WARNING: Connection of both grounds (the AC power cord and the supplementary ground conductor) is
required for safe operation of the G430 Media Gateway and EM200.
