Incoming as well as outgoing wires and
wires for extra low voltages (ELV) must be
separated from dangerous electrical cables
(SELV circuits) by using a double resp.
increased isolation.
All selected wires and isolations must be
conform to the provided voltage- and
temperature-ranges. Further all country- and
application-specific standards, which are
relevant for structure, form and quality of the
wires, must be ensured. Indications about
the permissible wire cross-sections for
wiring are described in the Technical
Specifications.
Before first start-up it must be ensured that
all connections and wires are firmly seated
and secured in the screw terminals. All
(inclusively unused) terminals must be
fastened by turning the relevant screws
clockwise up to the stop.
Overvoltages at the connections must be
limited to values in accordance to the
overvoltage category II.
For placement, wiring, environmental
conditions as well as shielding and
earthing/grounding of the supply lines
the general standards of industrial
automation industry and the specific
shielding instructions of the
manufacturer are valid.
