For LOW a real ground connection is required. If an input is left open it is detected as HIGH. Input signals >5V may destroy the SAMOTRONIC101.

With fixed functions it is only necessary to connect the SAMOTRONIC101 to the supplying voltage and to change the direction if necessary. Mounting: The unit must be installed in a case so that the user is not able to access it while working. Otherwise and for maintenance purpose the unit must be used in an antistatic environment and the user must be discharged with standard ESD-protection equipment. Take care to leave minimum distance to holes and gapes in the case to prevent electrostatic discharges. A typical value for 8kV (EN50082-1/2) is 8mm (DIN-VDE0110-1), depending on environment, humidity and temperature conditions. Cables: Max. cable length for all control inputs (screw terminal port 2-6) is 3m. At the clock input (screw terminal port 5) shielded wires must be used. SAMOtronic101 R7 E.doc 2/5
