The following requirements must be met when using the device:
4.1.1 Product-independent requirements
It must be ensured that the safety requirements of the respective application
correspond to the requirements stated in these instructions.
The specified technical data indicated in these instructions must be complied with.
The principle of normally closed operation must be applied to all external safety
circuits connected to the system.
The following points have to be ensured in the application by taking administrative
measures:

(intermittent operation).
The self-test starts when the supply voltage is applied.
(→7.2Supplyvoltage)
• The safety-relevant relay contacts have to be protected by respective fuses of
3.6 A as short-circuit/overload protection.
(→7.6Switchingoutputs14-23and24-24)
