Important information
WARNING
Ine
ffectiveness of the protective device due to undetected short-circuits between the
test pulse generators
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Rule out short-circuits between the odd-numbered test outputs X1, X3, X5 and X7
through suitable wiring (e.g. separate routing, protected cables).
►
Rule out short-circuits between the even-numbered test outputs X2, X4, X6 and X8
through suitable wiring (e.g. separate routing, protected cables).
►
Configure the test outputs of the Flexi Soft expansion modules with test pulse
widths ≤4ms and a test pulse interval ≥200ms.
