2.6 Grounding Checks
The product must only be connected to a power source that has a safety electrical earth connection.
Warning
If more than one product is fitted in a rack, the earth connection to the rack is even more

The earth connection to the rack must be checked before switching on, by an electrical engineer who is
qualified to the appropriate local and National standards to perform the check.
