6 Installation
6.1 General
Regarding electric installation the local regulations in the respective countries
(e.g. VDE 0100 in Germany) must be referred to.
The NivuSonic CO 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 resis-
tance with 500 kOhm min. is necessary.
The section 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 unit protection rating is
IP 65.
The maximum switching voltage on the relay contacts must not exceed 250V.
According to Ex-protection it must be checked if the devices power supplies
must be integrated into the facility’s emergency shutdown conception.
6.2
Transmitter installation and connection
6.2.1 General
The transmitter mounting place has to be selected according to certain criteria.
Please strictly avoid:
-
direct sunlight (use weatherproof cover if necessary, e.g. NIVUS weather-
proof cover Art. No. ZMS0 180000)
-
heat emitting objects (max. ambient temperature: +50 °C)
-
objects with strong electromagnetic fields (e.g. frequency converters, con-
tactors / relays, electric motors with high rated input or similar)
-
corrosive chemicals or gas
-
mechanical shocks
-
direct installation close to footpaths or travel ways
-
vibration
-
radioactive radiation
For fastening the wall mount enclosure, depending on place of mounting, use 4
machine screws size M5 in suitable length as well as the necessary nuts and
shims. Or use 4 wood screws with min. diameter 4.5 mm. These screws must
reach min. 40 mm into the wall or min. 50 mm into appropriate dowels (to be
set).
