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 M4000 multiple light beam safety device 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 earth (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 60204E1. Suitable power supplies are
available as accessories from SICK (Siemens type series 6 EP 1).
The plug alignment (direction of turn) in the housing may vary from device to device. You
can identify the correct pin assignment by the position of the pins in relation to each
other as shown in the drawings.
