6 Electrical Installation
This sections contains general information on electrical wiring.
6.1.1 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.
The ground wires of the power supply and analog outputs should be routed separately to avoid measurement
errors.
6.1.2 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.
