● Terminal voltage, V
– max. 2000 V for 200 V converters
– max. 2500 V for 400 V converters
● Overvoltage category III
● Pollution degree 2
● Suitable for SPD applications, type 1 or type 2
Alternatively, use a surge protection device, article number 5SD7 424-1 from Siemens AG.
Additional requirements relating to CSA conformance, frame sizes FSD ... FSG
Overvoltage category OVC III must be ensured for all connections of the power circuit. This
can mean that a surge suppressor must connected upstream on the line side. The rated
voltage of the surge suppressor must not exceed the line voltage, and must guarantee the
limit values (VPR) specified here.
