Electrical installation
6.1 General wiring guidelines
Power supply wiring
Heavy machinery and instrumentation should not share the same power supply wiring. If this cannot be
avoided, noise filters and surge protectors should be used. Most UPS devices have those features already
integrated.
General guidelines for signal cables
The following guidelines are derived from European Standard EN 50170 for the transmission of signals by
copper wires. When planning an installation, the rules provided by EN 50170 should be followed under
consideration of local circumstances to determine the position of machines and equipment.
All ROTRONIC products are tested for Electromagnetic Compatibility according to EMC Directive
2004/106/EG and following European standards:
-
EN 61000-6-1: 2001, EN 61000-6-2: 2005
-
EN 61000-6-3: 2005, EN 61000-6-4: 2001 + A11
Whenever the level of electromagnetic interference is expected to be high, both the instruments and signal
cables should be placed as far away as possible from the source of interference.
In general, signal cables should be installed in bundles or channels / conduits, separate from other cables as
indicated in the table below:
