4.2 NOTES ON CONNECTIONS
For the correct operation of the safety light curtains, the following precautions regarding the electrical connections
have to be respected:

Do not place connection cables in contact with or near high-voltage cables and/or cable undergoing high
current variations (e.g. motor power supplies, inverters, etc.).

The device is already equipped with internal overvoltage and overcurrent suppression devices.

The use of other external components is not recommended.
Example: connection to the safety relay SE-SR2
Fig 21 - Connection to SE-SR2 Safety Relais
The figures show the connection between the safety light curtains and the safety relay of the SE-SR2 series
functioning in the Automatic Restart mode (left side) and Manual Restart with monitoring (right side).

Do not use varistors, RC circuits or LEDs in parallel at relay inputs or in series at OSSD outputs.

The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel, but can be used
separately, conforming to the plant’s safety requirements.

If one of these configurations is erroneously used, the device enters into the output failure condition (see
cfr.
USER INTERFACE AND DIAGNOSTICS page 30 ).
