If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the E-727 in the case of malfunction or failure of the system. If touch voltages exist,
touching the E-727 can result in serious injury or death from electric shock.
Connect the E-727 to a protective earth conductor before start-up (p. 48).
Do not remove the protective earth conductor during operation.
If the protective earth conductor has to be removed temporarily (e. g. in the case of
modifications), reconnect the E-727 to the protective earth conductor before starting it up
again.
