The maximum permissible voltages and the associated
maximum permissible short-circuit currents for the
corresponding gas group may be taken from Table A1 in the
standard DIN EN 50020, 1994 Edition.
In order that the maximum permissible temperature at the
solenoid coil of the valve installed is not exceeded, the following
limits to the applied power for use in the corresponding
temperature class must be observed:
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.

• 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.
