NOTE
Pre-assembled cables can be found online at:
•
NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
•
Connect the connecting cables in a de-energized state. Do not switch on the
voltage supply until installation is complete and all connection work on the device
and controller has been finished.
•
Isolate the wires of unused digital outputs at the control cabinet.
•
Use proper connecting cables and male connectors for the application or environ‐
mental conditions,
.
•
The specified device enclosure rating is valid only with suitable mating connectors
or with the protective caps installed.
•
Electrical protection class III and ES1 supply voltage.
•
The supply voltage must be as specified in the technical data,
•
Configure the circuits connected to the device as ES1 circuits or as SELV circuits
(SELV = Safety Extra Low Voltage). The voltage source must meet the requirements
of ES1 (EN 62368-1) or SELV (EN 60950-1).
•
The voltage supply via a power supply unit must be capable of buffering a brief
power failure of up to 20 ms.
•
Prevent product damage caused by short-circuit: The device supply voltage input is
equipped with reverse polarity protection. The internal functional earth is directly
connected to the metal housing of the device. The internal functional earth also
corresponds to the negative pole of the supply voltage.
