Notes for units with EEx-i approval
• Take suitable measures to avoid an electrostatic discharge from the plastic
parts of the housing (see EN 100 015 - 1).
• No component should be connected to the inputs and outputs of the circuit
board whose electrical data is outside the limits determined for intrinsically safe
operation quoted in the data sheet of the positioner.
• Work out on the device with the housing open should not be carried in very
damp or aggressive atmospheres. Take precautions to exclude unintentional
mechanical damage to the circuit boards or their components. Limit the period
during which the unit is opened to that which is absolutely necessary.

Please comply with the following:
• In the case of installation and operation in areas that have a risk of explosion, the respective national
regulations. In Germany, this is VDE 0165.
• When making electrical connections to the inherently safe circuit, the information given in the
corresponding conformity certificates.
• Always follow the information contained in the ATEX approval.
