General grounding requirements
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.
Two safety grounds are required to ensure safe operation of each Branch Gateway and each
EM200: the ground conductor that is part of the AC power cord, and the field-installed green/
yellow conductor referred to as the Supplementary Ground Conductor. Both safety grounds must
be connected to an approved ground. If a power cord accompanies the Branch Gateway or
EM200, use that cord whenever possible.
Installation location
Select a location for the Branch Gateway or EM200 installation that is close enough for use with
the supplied secondary grounding conductor. If this location requirement is not met, contact a
licensed electrician to install a Supplementary Ground Conductor per Article 250 of the National
Electrical Code (NEC).
