Ground terminal — If the power outlets do not provide connections to
the protective ground of the building, connect ground straps between this
terminal lug on all BMEs and a hard building ground. Secure the ground
straps with the nut and washer included with each BME.
The building installation shall provide a means for connection to protective
earth; and
The equipment is to be connected to that means; and
A SERVICE PERSON shall check whether or not the socket-outlet from
which the equipment is to be powered provides a connection to the building
protective earth (ground). If not, the SERVICE PERSON shall arrange for the
installation of a PROTECTIVE EARTHING CONDUCTOR from the separate
protective earthing terminal to the protective earth wire in the building.
Primary and Redundant AC Power Input connectors — Connect a standard
IEC power cord between the rear panel Primary AC Power Input connector
