All parameters are specified at 24V, 5A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
16. Safety and Protection Features
Isolation resistance
>500MOhm
At delivered condition between input and output,
measured with 500Vdc
Output over-voltage protection
typ. 16.5Vdc
max. 17Vdc
In case of an internal defect, a redundant circuit limits the maximum output
voltage to 17V. The output shuts down. To attempt a restart, turn the input
power off for at least 90s.
Class of protection
II
According to IEC 61140
Degree of protection
IP20
According to EN/IEC 60529
Over-temperature protection
Not Included
Input transient protection
MOV (Metal Oxide Varistor) For protection values see chapter 14 (EMC).

17. Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate
test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all phase-terminals together
as well as all output poles before conducting the test. When testing, set the cut-off current settings to the value in the
table below.
It is recommended that either the (+) pole or the (–) pole shall be connected to the protective earth system. This helps to
avoid situations in which a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.
