13 General Installation Instructions
For electric installation the local regulations in the respective countries (in Germany e. g.
VDE 0100) must be referred to.
WARNING Separate protection
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 re-
sistance of 250 kOhm. If the voltage exceeds 42 V DC an isolation resistance 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 protection rating is IP65. The max-
imum allowed switching voltage on the relay contacts must not exceed 250 V. According to
Ex protection it must be checked if the devices power supplies must be integrated into the fa-
cility’s emergency shutdown conception.
14 Transmitter Installation and Connection
Important hints on installation

Ensure proper installation.

Follow applicable legal or operational guidelines.

Improper handling may lead to personal injuries and/or equipment damage.
14.1 General
The transmitters mounting place has to be selected according to certain criteria.
Please strictly avoid:
•
Direct sunlight (use weatherproof cover if necessary)
•
Heat emitting objects (max. ambient temperature see chapter “10 Specifications”)
•
Objects with strong electromagnetic fields (e. g. frequency converters or similar)
•
Corrosive chemicals or gas
•
Mechanical shocks
•
Installation close to footpaths or travel ways
•
Vibrations
•
Radioactive radiation
During installation works keep in mind that electronic components may be irreversibly dam-
aged due to electrostatic discharge. Therefore avoid intolerably high electrostatic charge dur-
ing installation by implementing appropriate grounding measures.
