Conductor
Both safety grounds must be connected to an approved ground. If a power cord accompanies
the G700, use that cord whenever possible.
For DC Input: - The +48Vdc lead provided for DC power input to the G700 Media Gateway
must be grounded at the source to an approved ground. The -48Vdc is the active lead. Both
leads must be floating at the input to the G700. In addition, the Supplementary Ground
Conductor must be installed on the G700 and connected to an approved ground.
The customer must select a location for the G700 Media Gateway installation that is no more
than 25 feet (7.6 m) from an approved ground. If this location requirement is not met, the
customer must contact a licensed electrician to install a Supplementary Ground Conductor per
Article 250 of the National Electrical Code (NEC).
