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.).

Do not connect in the same multi-pole cable the OSSD wires of different light curtains.

The TEST wire must be connected through a N.O. button to the supply voltage of the ESPE.

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 31 - 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
separatel
y, 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 54 ).
The TEST button must be located in such a way that the operator can check the
protected area during any test.
The RESET/RESTART/ALIGN button must be located in such a way that the operator
can check the protected area during any reset operation.
