Explosion protection Zone 2
It is recommended to use the positioner with explosion prot-
tection "intrinsically safe" acc. to EN 50020 an EN 50014
(consider temperature class). In the EU these positioner
may be operated in Zone 2 with non-intrinsically safe
circuits if the operating values do not exceed the maximum
reference values. The non intrinsic safe circuits has
additionally fulfill the requirements of EN61010-1 (IEC 1010-1),
protection grade III, overvoltage category I (transient voltage
lower than 40 %).
1) With appropriate order only
2) National requirements must be observed
