®Instruction ManualOCM Pro CFPage 24 OCM Pro CF - Rev. 07 as of 04.12.20126 Installation6.1 GeneralFor electric installation the local regulations in the respective countries (e.g. VDE0100 in Germany) must be referred to.The OCM Pro CF power supply must be separately protected by a 6 A slow-blow fuse and has to be isolated from other facility parts (separate turn-off,e.g. by using an automatic cut-out with >B< characteristics).Before feeding the rated voltage the transmitter and sensor installation must becorrectly completed. The installation should be carried out by qualified personnelonly. Further statutory standards, regulations and technical rulings have to betaken into account.All outer circuits, wires and lines connected to the device must have a minimumisolation resistance of 250 V. If the voltage exceeds 42 V DC an isolation re-sistance with 500 kOhm min. will be required.The cross-sectional dimension of the power supply wires must be 0.75 mm 2(0.03 in2) and must be in accordance to IEC 227 or IEC 245. The maximum al-lowed switching voltage on the relay contacts must not exceed 250 V and notundershoot 10 mA.According to Ex protection it must be checked if the devices power suppliesmust be integrated into the facility’s emergency shutdown conception.
