1)
The power supply unit must be able to jumper a brief power failure of 20 ms as specified in IEC 60204-1.
Suitable power supply units are available as accessories from SICK.
Battery-powered systems must be able to jumper brief power failures of 5 ms.
2)
A fuse with a maximum rated current of 2 A (slow blow) must be installed in the isolated 24 V DC power
supply circuit to the device in order to limit the available current.
3)
The voltage level must not fall below the specified minimum voltage.
4)
Applies to the voltage range between -30 V and +30 V.
5)
The OSSDs must operate loads that require at least 2 mA each to switch to the ON state.
6)
All control inputs must be powered from the same voltage supply as the safe multibeam scanner.
