Permitted operating height
The values stated in the technical details apply to the use of the device in operating heights
up to max. 2000 m above sea level. When used in greater heights, constraints have to be
taken into account:
} Permitted maximum operating height 5000 m
} Only device versions with UB 24 V DC are permitted (order no. 750104, 751104, 751184)
} Reduction of rated insulation voltage and rated impulse withstand voltage for applications
with safe separation:
