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).
