7 Installation
7.1 General
For electric installation the local regulations in the respective countries
(e.g. VDE 0100 in Germany) must be referred to.
The OCM F 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 be
correctly completed. The installation should be carried out by qualified personnel
only. Further statutory standards, regulations and technical rulings have to be
taken into account.
All outer circuits, wires and lines connected to the device must have a minimum
isolation 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 in
2
) and must be in accordance to IEC 227 or IEC 245. The device protec-
tion rating is IP 65.
The maximum allowed switching voltage on the relay contacts must not exceed
250 V. According to Ex protection it must be checked if the devices power sup-
plies must be integrated into the facility’s emergency shutdown conception.
