5 Electrical installation
Switch the entire machine/system off line!
The machine/system could unintentionally start up while you are connecting the devices.
⋅ Ensure that the entire machine/system is disconnected during the electrical
installation.
Connect OSSD1 and OSSD2 separately!
You are not allowed to connect OSSD1 and OSSD2 together, otherwise signal safety will
not be ensured.
⋅ Ensure that the machine controller processes the two signals separately.
⋅ Contactors connected in series must be positively guided and monitored (see
section 5.3 in “External device monitoring (EDM)” on page 34).
Only connect the OSSDs to a single subsequent switching element!
⋅ Each output signal switching device (OSSD) is only allowed to be connected to one
switching element (e.g. relay or contactor). If several switching elements are required,
then you must choose a suitable form of contact duplication.
Prevent the occurrence of a potential difference between the loads and the protective
device!
⋅ If you connect loads to the OSSDs that are not reverse polarity protected, then you must
connect the 0 V connections for these loads and the related protective device
separately, one after the other, to the same 0 V terminal strip. Only then is it ensured
that in the case of a fault, it is not possible for a potential difference to form between
the 0 V connections for the loads and the related protective device.
• The two outputs are protected against short-circuits to 24 V DC and 0 V. When the light
path is clear, the signal level on the outputs is HIGH DC (at potential), when the light
path is interrupted or there is a device fault the outputs are LOW DC.
• The V200/V300 safety camera system meets the interference suppression
requirements (EMC) for industrial use (interference suppression class A). When used in
residential areas it can cause radio interferences.
• To ensure full electromagnetic compatibility (EMC), functional earth (FE) must be
connected.
