Ground conductor
A Supplementary Ground Conductor is provided with the equipment, and is constructed of 10 AWG
(4.0 mm
2
) wire, with an insulated ring terminal crimped to one end that is suitable for the #8 (M4)
stud/screw on the rear of the Branch Gateway or EM200 chassis.
The customer will need to provide a means of connecting this Supplementary Ground Conductor to
an approved ground according to Article 250 of the National Electrical Code (NEC).

Ground block
A ground block, supplied by the customer and installed by an electrician, is available for use when
you are installing multiple Branch Gateways or EM200s . The ground block, intended for rack
mounting, has ten terminals available for terminating Supplementary Ground Conductors. Up to ten
Branch Gateways or EM200s 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.
Danger:
Failure to install both grounds will void the Product Safety certifications (UL and 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, Norway, and Sweden, the Branch Gateway and EM200s 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 Branch Gateway or EM200s is gained by the use of a tool
(such as a lock and key) or other means of security.
Warning:
For installations in Finland, Norway, and Sweden, the Branch Gateway and EM200 rely on two
ground connections (mains plug with an earth contact, and a Supplementary Ground
Conductor).
