to a low-resistance voltage source, otherwise the
positioner may be destroyed.
• Always use a high-impedance power source.
• Observe the static destruction limit specified in the "Technical specifications (Page 43)".
Note
Improvement of interference immunity
• Lay signal cables separate from cables with voltages > 60 V.
• Use cables with twisted wires.
• Keep the device and the cables at a distance from strong electromagnetic fields.
