1) PM-D F3 power module only approved up to Category 3

2) F kit required for standard motor starter only; already integrated in high feature motor starter

The SIGUARD safety system is based on special terminal and power modules that can be combined with the ET 200S motor starters and a failsafe kit to achieve the highest safety category

4(according to EN 954-1). It enables the evaluation of emer- gency stop circuits, the monitoring of protective doors or the im- plementation of time-delayed shut-downs. The costs involved in the configuration and wiring of conventional safety systems are no longer incurred. All standard safety applications can be cov- ered with SIGUARD (see the ET 200S manual for examples of applications).
