Grounding checks

Edit online

The product must be connected to a power source that has a safety electrical ground connection.

CAUTION:
If one or more 5U enclosures go into a rack, the importance of the ground connection to the rack increases because the rack has a larger "EARTH LEAKAGE CURRENT" ("TOUCH CURRENT").

Examine the ground connection to the rack before turning it on. An electrical engineer who is qualified for the appropriate local and national standards must do the examination.
