DANGER
Risk of electric shock due to high voltage
An electric shock leads to serious injuries or even death.
➢ Observe the permissible protection class and earthing.
The NEA/NEG may only be operated with the correct
connection of the protective conductor.
➢ Perform all work only with insulated tools suitable for the
application.
➢ All work on the system may only be carried out in a volt-
free state.
➢ Never open the terminal box cover when voltage is ap-
plied.
➢ Never loosen or remove paint-sealed screws.
➢ Never touch or remove safety covers.
➢ Protect the NEA/NEG against falling parts during all
work. Metal parts can cause a short circuit within the
NEA/NEG.
WARNING
Spark formation
Opening the terminal box cover of the NEA/NEG in Ex-
zones can cause spark formation and thus lead to an explo-
sion due to ignition of an explosive atmosphere.
➢ Never open terminal box covers in a potentially explosive
atmosphere or when voltage is applied.
➢ If terminal box covers or unbalance covers are open,
check the condition and correct positioning of the seals.
➢ Damaged seals must be replaced immediately.
➢ The mechanical protection of the housing (IP6X) must be
assured after assembly of the covers.
