• Transient over voltages (<50µs) must not exceed
1000 V (peak value) between the phases and 2000 V
against ground.
Note: Ungrounded mains always need additional surge protection in
the mains input.
High voltage mains If the mains voltage exceeds the maximum allowed input voltage of
the power supply module, a transformer has to be used to bring it
into the specified range.
