1.3 Installation
The device is only allowed to be installed and operated within the permissible
temperature range. Please ensure 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 double resp.
increased isolation.
All selected wires and isolations must be conforming 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.
Overvoltage 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 on www.kuebler.com/download.html --> [General EMC Rules
for Wiring, Screening and Earthing].
1.4 Cleaning, Maintenance and Service Notes
To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For
the rear no cleaning is necessary. For an unscheduled, individual cleaning of the rear the
maintenance staff or assembler is self-responsible.
During normal operation no maintenance is necessary. In case of unexpected problems,
failures or malfunctions the device must be shipped for back to the manufacturer for
checking, adjustment or reparation. Unauthorized opening and repairing can have
negative effects or failures to the protection-measures of the unit.
The service interval of the SMCX device is 1 year, in case of continuous operation the
SMCX unit must be switched on and off for at least 1 times a year.
