front of ground or installation lines with
increased potential, which is required to
prevent unintentional contact of service
staff with live parts.

• Bundled disconnection of all auxiliary
control circuits from potential earth.
Mounting rails, end brackets, further marking material see “Accessories”
• A test voltage can be applied using the
screening connection of the control
cable, which is normally routed on the
enclosure, with the help of an appropria-
te separation. This permits to check
whether the screening line is correctly
functioning. For this test, an insulated
feed-through plate is required.
