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”. You can download
that manual by the link

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.
