Grounding checks
The product must only be connected to a power source that has a safety electrical earth connection.
Warning: If more than one 2U enclosure goes in a rack, the importance of the earth
connection to the rack increases, because the rack will have a larger “EARTH LEAKAGE CURRENT”
(“TOUCH CURRENT”).
Examine the earth connection to the rack before the switch on: an electrical engineer who is qualified to the appropriate local and national standards must do the examination.
