ELECTRICAL CONNECTIONS AND CONNECTORS
Before making the electrical connections, always check that the voltage available matches that
indicated in the technical data.
The Emitter and Receiver must be powered at 24VDC ±20%.
The external power supply must comply with EN 60204.
The electrical connections must be made according to the diagrams provided in this manual.
In particular, never connect other devices to the connectors of the Emitter and Receiver.
To assure dependable functioning, using a diode bridge power supply unit, its output capacity
must be at least 2000
µ
F for each ampere absorbed.
