Power devices which are a powerful source of interference must be installed in a separate location
away from the input and output circuits for signal processing. The cable routing for safety circuits
should be as far away as possible from the cables of the power circuits.
Ì
To avoid EMC interference, the physical environmental and operating conditions at the in-
stallation site of the device must comply with the requirements according to the standard
EN 60204-1:2006, section 4.4.2 (EMC).
