1)
Only in combination with a suitable test device.
2)
Between two requirements on a safety-related response of the device, at least 100 external tests must
be carried out.
3)
The external voltage supply of the device must be capable of buffering brief power failures of 20 ms as
specified in EN 60204. Suitable power supply units can be obtained as accessories from SICK (Siemens
Series 6 EP 1).
4)
A fuse rated maximum 4 A shall be installed in the isolated 24 V DC power supply circuit to the device in
order to limit the available current.
5)
Only in combination with a suitable test device, the response time of which must be taken into considera‐
tion.
