Ground Block; Restricted Access Location; Approved Grounds - Avaya G350 Installing And Upgrading

Installing the Avaya G350 Media Gateway

Ground block

A ground block is available for use when multiple G350 Media Gateways are being installed.
The ground block, intended for rack mounting, has ten terminals available for terminating
Supplementary Ground Conductors. Up to ten G350 Media Gateways can be grounded at the
block installed close to the equipment (on a rack) and then a single ground conductor can be
routed from the same block to an approved ground. If the ground block is to be used, it must be
ordered separately.
!
DANGER:
Failure to install both grounds will void the Product Safety certifications (UL and
DANGER:
the CE Mark) on the product, as well as allow a hazard to be present that could
result in death or severe personal injury.

Restricted Access Location

In Finland and Norway, the G350 Media Gateway must be installed in a Restricted Access
Location, due to unreliable earthing concerns. A Restricted Access Location is defined as
access that can be gained by only Service Personnel or Customers who have been instructed
about the reasons for the restricted access and any safety precautions that must be taken. In
these cases, access to the G350 is gained by the use of a tool (such as a lock and key) or other
means of security.
!
WARNING:
For installations in Finland and Norway, the Avaya G350 Media Gateway relies on
WARNING:
two ground connections (mains plug with an earth contact and a Supplementary
Ground Conductor).

Approved grounds

An approved ground is the closest acceptable medium for grounding the building entrance
protector, entrance cable shield, or a single-point ground of electronic telephony equipment. If
more than one type of approved ground is available on the premises, the grounds must be
bonded together as required in Section 250-81 of the NEC for the US or per the local electrical
code regulations in the country of installation.
