5 Electrical Installation
This section describes the general safety precautions for electric wiring.
5.1.1 Cable Grip and Cable Specifications
The PF4 comes with a M16 cable grip with screw cable gland. The M16 cable grip offers effective sealing if
cables with external diameters of 6 to 7 mm (0.236 to 0.275 inch) with connection wires per 18 AWG are used.
5.1.2 General Connection Information
Heavy machinery and measuring instruments should not share the same electric cables for power supply. If this
cannot be avoided, noise filters and surge protectors should be used, as integrated in most UPS devices.
5.1.3 Signal Cable Information
The following guidelines are derived from the European standard EN 50170 for the transmission of signals by
copper wires. Note on installation planning: when determining the position of machinery and equipment, the
rules given in EN 50170 should be followed with due regard to local circumstances.
All ROTRONIC products are tested for electromagnetic compatibility according to EMC Directive 2004/108/EC
and the following European standards:
- EN 61000-6-1: 2007, EN 61000-6-2: 2005
- EN 61000-6-3: 2007, EN 61000-6-4: 2007
Whenever the level of electromagnetic interference is expected to be high, both the devices 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:
