EMC Guidelines
All motrona devices are designed to provide high protection against electromagnetic interference.
Nevertheless you must minimize the influence of electromagnetic noise to the device and all
connected cables.
Therefore the following measures are mandatory for a successful installation and operation:
•
Use shielded cables for all signal and control input and output lines.
•
Cables for digital controls (digital I/O, relay outputs) must not exceed a length of 30 m and
are allowed for in building operation only
•
Use shield connection clamps to connect the cable shields properly to earth
•
The wiring of the common ground lines must be star-shaped and common ground must be
connected to earth at only one single point
•
The device should be mounted in a metal enclosure with sufficient distance to sources of
electromagnetic noise.
•
Run signal and control cables apart from power lines and other cables emitting
electromagnetic noise.
Please also refer to motrona manual “General Rules for Cabling, Grounding, Cabinet Assembly”.

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 and reparation (if necessary). Unauthorized opening and repairing can have
negative effects or failures to the protection-measures of the unit.
