Electrical installation
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
beams are interrupted or there is a device fault the outputs are LOW DC.
The safety light curtain C4000 meets the interference suppression requirements (EMC)
for industrial use (interference suppression class A). When used in residential areas it
can cause interference.
To ensure full electromagnetic compatibility (EMC), functional earthing (FE) must be
connected.
The external voltage supply of the devices must be capable of buffering brief mains
voltage failures of 20 ms as specified in EN 60204C1. The power supply unit must
provide safe isolation (SELV/PELV). Suitable power supplies are available as
accessories from SICK (see section 12.7 “Accessories” on page 111).
System connections and extension connections in a cascaded system must be connect-
ed only if the system is off line. The configuration connection however, may be
connected/disconnected with the system on line.
