Safety Instructions and Responsibility

1.3. Installation

The device is only allowed to be installed and operated within the permissible
temperature range. Please ensure an adequate ventilation and avoid all direct
contact between the device and hot or aggressive gases and liquids.
Before installation or maintenance, the unit must be disconnected from all
voltage-sources. Further it must be ensured that no danger can arise by
touching the disconnected voltage-sources.
Devices which are supplied by AC-voltages, must be connected exclusively by
switches, respectively circuit-breakers with the low voltage network. The
switch or circuit-breaker must be placed as near as possible to the device and
further indicated as separator.
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" chapter.
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. Please find all respective hints and rules www.kuebler.com/emc.
